For Your Viewing Pleasure – Part 1
(Courtesy Of ABC 33/40)

Recently ABC 33/40 presented its one day weather seminar – Storm Alert XTREME. These presentations are one of the best outreach tools for reaching the general public with severe weather information and training, since as everyone knows that “Spann’s The Man”, and that’s
a powerful incentive to attend.

In case you, as I did, happened to miss the event, we are in luck as ABC 33/40 has posted videos of the event on YouTube.

The following are the videos of both the 2016 & 2017 events. They are divided into segments and I included the runtime of each, so you know how manage your viewing time, as the presentations are around four hours long.

Another set of videos I am including are ABC 33/40’s coverage of the April 27, 2011 tornado outbreak, which hit in two major waves.

The first video is wall to wall coverage as the morning wave of storms moved through.

These videos are important both from a historical perspective and in the case of the Jefferson County coverage, as a reminder that portions of Jefferson County suffered extreme damage also.

Last year a major network carried a documentary covering the April 27th tornado outbreak. It covered Hackleberg, Phil Campbell and extensively covered the devastation and recovery in Tuscaloosa. I waited anxiously to see their coverage of the damage cause by the same tornado in Jefferson County, but, instead of mentioning anything at all, credits rolled and a sitcom came on instead.

This is not unusual. In most coverage of the April 27th outbreak, Jefferson County is usually only briefly mentioned, if it is mentioned at all.

While I don’t want to sound like I’m in any way downplaying Tuscaloosa’s tragedy, which I most assuredly am not, for they suffered horrific loses both in people and property, it must be remembered that 21 souls were taken in Jefferson County by the same tornado, now evolved from a strangely photogenic storm into a grotesquely unphotogenic 1.5 mile wide mass of destruction, as Concord, parts of Pleasant Grove, McDonald’s Chapel, Pratt City and Smithfield were flattened or swept away. These should not be forgotten.

The NWS in its final storm summary http://www.weather.gov/bmx/event_04272011tuscbirm describes the scenario as follows:

“The tornado crossed CR 99 and moved into western Jefferson County, 4 miles north of Abernant.

In the Concord area, the tornado became violent once again with total destruction noted to a few small retail shops along County Road 46. Only piles of debris were left on the foundation. In addition, several cinder block homes were completely destroyed with debris swept away (EF-4). Numerous other homes in the area were destroyed with only a few interior walls left standing.

The tornado continued northeastward out of the Concord area and into the Pleasant Grove community. EF-4 damage was prevalent here, with slabs wiped clean, though the debris from each home had not been removed by the winds. The majority of it remained within a couple of yards of the home. It was here in Pleasant Grove where evidence of vehicles being moved by the winds become obvious, though most were only tossed 10 to 15 yards if they were picked up at all. Additionally, wind rowing of debris was evident throughout the Pleasant Grove community which is characteristic of a storm of this magnitude.

The tornado quickly moved out of the Pleasant Grove area and into the McDonald Chapel community. It was here in McDonald Chapel where evidence of a slight weakening of the tornado became clear. No vehicles were tossed, only pushed slightly from their original position. Many homes in this area were constructed by the method of pier and beam foundation, which led to some of the major destruction, as this construction will not withstand winds of this magnitude. A four-sided brick home in the same area only lost a roof and no exterior walls, which is indicative of EF-2 damage. At least one death occurred here.

After the tornado moved through the McDonald Chapel area, it moved into the area of Smithfield Estates, with significant home damage along Cherry Avenue between Daniel Payne Drive and Veterans Memorial Drive. Numerous homes sustained damage in this area, and a 2-story apartment complex had a large portion of its roof lifted and removed. The Bethel Baptist Church also sustained significant damage to its roof, though the main structure of the building was still intact. The damage sustained in this area is consistent with EF-2 wind damage. Although not a main damage indicator, there was also evidence of vehicles being moved, but only a couple of feet.

By the time the tornado reached Interstate 65, it was evident that the storm was losing its energy. The damage in the Fultondale area included folded highway light poles along the interstate, and roof damage to the Days Inn on U.S. Highway 31. To the east of US-31, the damage quickly diminished from EF-2 intensity to EF-1 and EF-0. The tornado lifted just to the west of Alabama Highway 79, about 2 miles north of the city of Tarrant, though the storm was not done. The storm did regenerate itself and eventually put down the EF-4 tornado in the Ohatchee area.”

Of the 64 people killed by this one massive storm, the 21 from Jefferson County, caused Jefferson County to be ranked fifth in the number people killed that stormy day. Tuscaloosa County was first having lost 43, then Dekalb County 35, Franklin County 26 and Marion County 25.

I watched this storm from Red Mountain knowing I was watching people die.

Let us never forget them.

I know I never will.

Mark’s Almanac

May is the fifth month & third month of the Roman calendar. May is named for the Greek goddess Maia, who was identified with, Bona Dea, the Goddess of Fertility, who was celebrated in May.

Since ancient times the first day of the month, “May Day” has been a time of celebration. In Rome it honored Flora, the goddess of flowers.

On May the fifth Mexican’s celebrate Cinco De Mayo, the celebration Mexico’s 1862 victory over Napoleon III’s forces at Puebla. This is not, as many assume, Mexico’s Independence Day, which is actually on September 16.

Rainfall decreases in May as the Azores-Bermuda High strengthens, expands Westward over the Southeastern US & begins rerouting storm systems northward.

The door opens to the Gulf of Mexico & Gulf moisture spreads northward over the continent.

The center of maximum tornadic activity also shifts northward over the Nation’s Heartland. May is the peak tornado month, with a 42% increase over April’s amount.

Eastern Pacific hurricane season begins May 15, and although the North Atlantic hurricane season has not arrived, occasionally a tropical system will form in the Gulf of Mexico. In 110 years there have been 14 named storms.

Looking towards the sky, Mercury, at the beginning of the month is lost in the glare of the Sun, but, as the month progresses he reemerges in the morning sky and by May 17 will reach his highest point in the sky or “Greatest Western Elongation” of 25.8 degrees from the Sun. This is the best time to view Mercury since it will be at its highest point above the horizon in the morning sky. Look for the planet low in the eastern sky just before sunrise.

Brilliant Venus, magnitude -4.7 shines low in the east as dawn brightens. In a telescope it’s a crescent, thickening a little every morning. She is climbing in altitude and will read her highest point in the morning sky or “Greatest Western Elongation” on June 3, when she will be 45.9 degrees from the Sun. This is the best time to view Venus since it will be at its highest point above the horizon in the morning sky. Look for the bright planet in the eastern sky before sunrise.

Mars, magnitude +1.6 in Taurus glows in the west in late twilight.

Jupiter, shining very brightly at magnitude -2.4 in Virgo, is in the southeast at nightfall. It’s highest in the south by 11 or midnight daylight saving time. The star Spica, just a trace bluer, hangs 9° lower left of it, and 250 light years more distant.

Saturn, magnitude +0.3 in Sagittarius rises around 11 PM or midnight and glows highest in the south before dawn, upper right of the Sagittarius Teapot. 470 light years beyond, super red giant Antares (magnitude +1.0) twinkles 18° to Saturn’s right in the early-morning hours.

This region of the sky has always been one of my favorite places to explore with binoculars, as you are looking into Sagittarius Arm of the Milky Way and toward the center of the galaxy. Give me a dark sky away from the city lights, a pair of binoculars, and I will easily become lost for hours draped on a car hood drifting among the star clouds and nebulae of Sagittarius. It’s almost like really being “up there”.

Uranus is hidden in the glare of the Sun.

Neptune is hidden the glow of dawn.

The Eta Aquarids Meteor Shower, an above average shower, peaks May 6 & 7. It is capable of producing up to 60 meteors per hour at its peak, but, most of the activity is seen in the Southern Hemisphere. In the Northern Hemisphere, the rate can reach about 30 meteors per hour, which is still a decent shower. It is produced by dust particles left behind by comet Halley, due to return in a mere 44 years in the summer of 2061. The shower runs annually from April 19 to May 28. The waxing gibbous moon will block out many of the fainter meteors this year. But if you are patient, you should be able to catch quite a few of the brighter ones. Best viewing will be from a dark location after midnight. Meteors will radiate from the constellation Aquarius, but can appear anywhere in the sky.

Full Moon will occur May 10th at 7:42 AM CDT. The Moon will be located on the opposite side of the Earth as the Sun and its face will be will be fully illuminated. May’s Moon is “Flower Moon” in Native American folklore, because of the abundance of spring flowers. It has also been called “Corn Planting Moon” & “Milk Moon”.

New Moon will occur May 25 at 2:45 PM CDT. The Moon will located on the same side of the Earth as the Sun and will not be visible in the night sky This is the best time of the month to observe faint deep sky objects such as galaxies and star clusters, as there will be no moonlight to wash out the evening sky.

3475 planets beyond our solar system have now been confirmed as of April 13, per NASA’s Exoplanet Archive http://exoplanetarchive.ipac.caltech.edu/

Last but, not least, World Naked Gardening Day will occur May 7.

Make sure to wear sunscreen, as some places are best not sunburned.

………………………………………………………………………………………………………………………………………


This month’s meeting will be on May 9 at 7PM at the National Weather Service Forecast office at the Shelby County Airport.

If for some reason you cannot attend the meeting in person, you can still participate via telephone. The teleconference number is 1-877-951-0997 & and the participant code is 741083.

Hope to see you there!

Hi Everyone,

I hope this finds you doing well.

As April arrives, I would urge each of you to check and recheck your storm preparations. This cannot be over emphasized. For, while we hope that we will have a quiet spring and be spared repeats of the disasters of the past, this cannot be counted on, and as surely as the sun rises in the morning, some April will bring tragedy upon us once again.

Human beings are reactive creatures. Once a disaster has occurred we are very diligent about preparing – for a while, anyway. Then as weeks turn into months, and months into years our memories fade, our attention moves on to other things and activities and our preparations along with our batteries literally corrode away in to dust. Then when we need them, our resources, once so carefully gathered, are not there for us.

So again, I urge you to revisit your preparations and supplies.

As they say “it is better to have it and not need it, than to need it and not have it.”

Just a brief reminder, that at our upcoming April 11 meeting the Nominating Committee will issue its recommendations for the upcoming ALERT elections in May. Nominations from the floor will be allowed the night of the elections in May.

I hope to see you there!

INSTRUCTIONS FOR OBSERVING TORNADOES – from the late 1800’s


Just for fun, the following is taken from “The Tornado” written by H. A. Hazen, published by the United States Weather Bureau in 1890. http://docs.lib.noaa.gov/rescue/rarebooks_1600-1800/QC955H391890.pdf

(Bear in mind several of these observation methods are outdated today. Some, like #9 in particular, are dangerous…)

“IF any one thing has been emphasized in these pages, it has been the extreme need of more light on this whole question. The earlier investigators of the phenomenon were untrammelled, to a large extent, by preconceived opinions, and it must strike every one that few substantial facts unknown to them have been brought out since their time. It is to be hoped that the number of those willing to aid in establishing the facts and ferreting out the mysteries will be largely increased, and it is for such these instructions are given.

1. It is very essential that one divests himself of every preconceived notion about the whirling, sucking, or any other action of a tornado. There is the utmost danger of seeing the tornado do what we think it ought to do. It would be far safer, if one has an inclination to such views, to deny that such a view is correct, and only to accept it after most incontestable proof.

2. Note the time of day carefully, and specify whether the time used is Eastern, Central, Mountain, or some city time.

3. The side of the track on which the observer stood should be given,

4. Note the appearance of the clouds in the distance,— whether they roll upward, come together from the north and south,— or any other phenomenon connected with them.

5. Special note should be made of a cloud of dust and its general appearance.

6. See whether the funnel-cloud is visible at a distance, or suddenly breaks into view on the approach of the tornado. If possible, locate the first appearance of the funnel by a tree, house, or object close by, and, after the tornado has passed, measure the distance from the observer’s position to that of the tornado when first seen.

7. If the observer is a thousand feet or more away from the funnel, or cannot see distinctly trees or objects in it or near it, he should not try to make detailed observations of the whirl, or any thing else at the tornado. Fix the attention on the motion of detached clouds. Make every effort, by comparison with trees and houses between the tornado and the observer, to get its height, width, and speed: these can be much better found out at a little distance than close to the cloud.

8. Make careful observations of all electric displays, the appearance of balls of fire, the sound of thunder, the roar of the tornado, etc.

9. If the observer is within a hundred feet of the tornado on the north side, he need have no fear, and may carefully examine all objects flying just above the ground. He should note carefully the foot, the middle, and the top of the funnel, to see whether any tree or object is carried to his right as he faces the funnel.

10. Note also whether any object is carried up straight in the funnel, or whether it is borne along in the swift wind. If there is an uprush in the tornado, it ought to be easily told; and the appearance will be very different from that if the object or house is borne along by the wind, and afterward inclined upward. If there is a sort of explosive effect, the upward motion will be more or less jerky, and not steady as in a stream. On the whole, the evidence seems to show something like an uprush, though it seems conclusive that this is not due to a vacuum in the tornado, as many think. It is very plain that nothing can be sucked into the tornado, because of a partial vacuum there; but if it rushes in or up, it must be borne or propelled by a stream of electricity, so to speak, or by a rush of air. One of the best illustrations of this has just come to hand from the storm at Bradshaw, Neb. This tornado passed over a tank ten feet long, three feet wide, and twenty inches deep, full of water. This tank was air-tight, and had an opening in the top one foot square. The observer reports that the tornado sucked all the water out of this tank. A moment’s reflection will show that this could have been done only by the insertion of the funnel into the opening one foot square. Of course this is absurd, and we must resort to some other explanation of the phenomenon.

11. After the tornado has passed, note the appearance of the houses for explosive effects.

12. Pay particular attention to the direction of the trees, making a separate observation on the south side, in the centre, and on the north side. See if any debris or objects have been carried in any case toward the west or south-west on the north side of the track, and measure the distance.

13. A note should be made of the width of the greatest destruction, not including houses unroofed on the borders; also the length of the path where it was most destructive, and the distance from the point at which it first struck the earth to the point at which it left the earth during the time of the greatest destruction.

14. Give the names of persons killed, if any.

15. Give an estimate of the loss to buildings, also specifying the number of buildings destroyed and their characters as to strength, etc.

16. A note should be made of the rainfall,— whether it was most abundant before, during, or after the tornado; also, if possible, the amount of rain at the centre of the track and at some point two thousand or three thousand feet on either side.

17. Careful note should be made of hail, size of stones, width of track, situation with respect to the main track, etc.

18. After the tornado the direction of the path should be most carefully determined.

19. All evidences of corks flying from bottles should be carefully looked for.

20. If one has a barograph, its record will be of the utmost value. If one has a barometer, an observation should be made by some one every minute till the tornado has passed. If the barometer is an aneroid, the face should be gently tapped before each observation. A steady watch of the needle may show any sudden fluctuation too rapid to be caught by reading the barometer. This instrument may be read in a dug-out or a cellar as well as in a house. Of course, every one will keep eyes and ears open for any and all phenomena to be noted in this remarkable outburst.”

Mark’s Almanac

The Romans called April “Aprilis”, probably from the word “aperire”, which means, “to open”. This time of year being when buds open. It was originally the second month of the Roman calendar, before Roman King Numa Pompilius added January & February in 700 BC.

Freezing weather comes to an end as Birmingham’s average last freeze is April 1, while Tuscaloosa’s is March 26. The record for the latest freeze date is April 21, 1953 for Tuscaloosa and April 23, 1986 for Birmingham.

April is less wet than March & rain becomes more localized and less widespread in nature. The sun heats the lower atmosphere near the ground and since the upper atmosphere is still cold, the warm air rises, reaches the dew point line, forms clouds & then it may rain. April is the first time in the spring season that favors local convective activity, which is why you have “April Showers”.

April is peak tornado month, with wide scale outbreaks possible. There are 2 ½ times the number of tornadoes as in March. 25% of the year’s tornadoes will have occurred by April 28.

From April 1950 to 2014, 8304 tornadoes were reported causing, as of 2013, 1770 deaths and 29,090 injuries.

As of 2011, Alabama is second only to Oklahoma in killer violent tornados, Oklahoma having had 40 and Alabama 39.

As of 2015, Alabama ranks fourth in the number of April tornadoes, following Texas, Oklahoma and Kansas. They along with Illinois belong to the “over 400 club” having had over 400 tornadoes since 1950.

As of 2015 Alabama leads the nation in F5 & EF5 tornadoes, having had 8, followed by Oklahoma with 7, and there is a three way tie for third between Iowa, Kansas and Texas with 6.

As of 2015 Alabama leads the nation in tornado deaths with 620, followed by Texas with 530 and Mississippi with 450.

The counties most likely to be struck by violent EF5 tornadoes are Lawrence, Limestone, Morgan, Madison and Marion, all of which have been struck three times.

Tuscaloosa has been stuck by four F4 & EF4 tornadoes including 1932, 1975, 2000 & 2011.

The suburbs of Birmingham, including Oak Grove, Pleasant Grove, McDonald Chapel and Smithfield have been struck by two F4 & EF4 tornadoes in 1956 & 2011 and by two F5 tornadoes in 1977 & 1998.

My Grandfather, who passed away in 1958, once said “someday a big tornado is going to go right up Jones Valley and tear everything up”.

Indeed there is no logical or climatological reason why and an EF4 or 5 tornado hasn’t struck or won’t strike the densely populated areas of Birmingham, including the high rises of downtown.

Whether it is due to “Divine Providence” or “random chance” otherwise known as “luck”, Birmingham has been spared.

When will that luck run out?

Some notable Alabama tornados in past Aprils include:

April 18, 1953 F3 Lee & Russell County 6 dead 195 injured
April 18, 1953 F3 Shelby County 8 dead 495 injured
April 15, 1956 F4 Jefferson County 25 dead 200 injured “McDonald Chapel Tornado”
April 18, 1969 F4 Montgomery, Bullock, Butler & Crenshaw Counties 2 dead 15 injured

April 3 & 4, 1974 “Super Outbreak” or produced at least eight tornadoes in Alabama, including four extremely intense and long-lived storms that swept the state killing eighty-six persons and injuring 949. The Huntsville area had an F3, F4 & an F5 tornado. The F4 tornado struck a half mile from where they were still digging out from an F3 tornado that had struck earlier in that day. Guin was literally wiped off the map, as was Xenia Ohio. The entire Eastern US and Southern Canada was affected during “The Day Of 100 Tornadoes”.

April 3, 1974 F5 Lamar, Marion, Winston, Lawrence & Morgan Counties 30 dead 230 injured
April 3, 1974 F4 Pickens, Tuscaloosa, Fayette, Walker & Cullman Counties 3 dead 178 injured
April 3, 1974 F5 Limestone-Madison 28 dead 260 injured
April 4, 1977 F5 Jefferson County 22 dead 130 injured “Smithfield Tornado”
April 1, 1998 F3 Russell County 2 dead 23 injured
April 8, 1998 F5 Tuscaloosa & Jefferson County 32 dead 259 Injured “Oak Grove Tornado”

April 25 – 28, 2011 Super outbreak was the largest and deadliest tornado outbreak on record,
with 358 tornadoes in 21 states and southern Canada. April 27 alone had 211 tornadoes. Of 348
people killed, 324 were tornado related, the other 24 being non-tornado storm related deaths, such as straight line winds.

Alabama was hit by two distinct waves of tornadoes, the first hitting during the early morning hours resulting in 52 injuries and the second in the afternoon and evening resulting in 238 deaths and 1946 injuries in a total of 62 tornadoes.

April 27, 2011 F5 Marion County 18 dead 100 injured
April 27, 2011 F4 Pickens, Tuscaloosa, Fayette, Walker & Blount Counties 13 dead 54 injured
April 27, 2011 F3 Marion County 7 dead 100 injured
April 27, 2011 F4 Greene, Tuscaloosa & Jefferson counties 65 dead 1500 injured
April 27, 2011 F3 Greene, Hale & Bibb counties 7 dead 50 injured
April 27, 2011 F4 Jefferson, St. Clair, Calhoun, Etowah and Cherokee counties 22 dead 81 injured
April 27, 2011 F4 Elmore, Tallapoosa & Chambers counties 7 dead 30 injured
April 3, 2012 F2 Tallapoosa & Chambers counties 1 dead 2 injured
April 28, 2014 F3 Limestone County 1 dead 30 injured

Beware of the storms of April.

Looking towards the sky, Mercury, sparkling at about magnitude –0.7 and fading in the evening twilight will reach his highest point in the sky, or “Greatest Eastern Elongation” on April 1. At that time the planet will be 19 degrees from the Sun. This is the best time to view Mercury. Look for the planet low in the western sky just after sunset.

Brilliant Venus, magnitude -4.2 passed between the Sun and Earth or “Inferior Conjunction” March 25th, but it did so at its maximum possible separation of 8° north of the Sun.

What does this mean?

Our solar system is shaped like a huge disk with the planets orbiting on a plane aligned with the Sun’s equator. However due to the planets colliding with large objects and perhaps due to the gravitational fields of other objects, such as large rogue planets, or “free floating planets” which are planets not gravitationally bound to a star, but, drifting through space, or other stars passing near the solar system eons ago, some of our planets orbital paths are distorted horizontally and not perfectly round, and vertically misaligned, orbiting slightly above or below the plane of the other planets.

Because of this, Venus will be passing slightly north of the Sun. This creates a rare occurrence where the planet is visible both before sunset and before sunrise. Can you find Venus at both dusk and dawn on the same day, or across the same night? Your chance is ending!

Mars, magnitude +1.5 has moved into Aries and is orange “star” moderately low due west in late twilight. The orange stars Alpha Arietis and Alpha Ceti in the same general area are fainter.

Jupiter, shining creamy white at magnitude -2.4 in Virgo, is low in the East after nightfall and higher in the Southeast by midnight. The star Spica dangles 6° lower below it.

On April 7 Jupiter will make his closest approach to Earth, or “Opposition” and his face being fully illuminated by the Sun, will be brighter than any other time of the year and visible all night long.

A medium-sized telescope should be able to show you some of the details of Jupiter’s cloud bands, while a good pair of binoculars should allow you to see Jupiter’s four largest moons – Io, Europa, Ganymede and Callisto as bright dots on either side of the planet.

Each night their positions will have changed as they continue the waltz they have danced with Jupiter for millennia uncounted.

Saturn, magnitude +0.4 in Sagittarius rises in the early morning hours and glows in the south by early dawn.

Uranus is hidden the glow of dusk.

Neptune is hidden the glow of dawn.

Comet 41P/Tuttle-Giacobini-Kresak (“T-G-K”) is becoming nicely visible in amateur telescopes high in the northern evening sky. It’s currently about magnitude 7 and may reach 6th magnitude through April. It’s large (passing relatively close to Earth) but rather diffuse.

Unfortunately it is just beyond naked eye visibility, but, if you have a telescope or even better yet, since they have more light gathering power, and let you use both eyes, grab the binoculars and give it a try! It is located roughly between the bowls of the Big & Little Dipper.

April’s Full Moon was known as “Full Pink Moon” in Native American folklore as it marked the reappearance of pink wild ground phlox. This will occur April 11 06:08 UTC or 1:08 AM CDT. This moon was also called by various tribes, the “Sprouting Grass Moon”, “Growing Moon”, “Egg Moon” and “Fish Moon”, as this is when shad swam upstream to spawn.

The Lyrid Meteor Shower which, runs annually from April16 – 25, peaks on the evening of April 22 and morning of April 23. This is a minor shower, with only 12 to 24 meteors per hour. These meteors sometimes produce bright dust trails that last for several seconds.

This shower is produced by dust particles left behind by comet C/1861 G1 Thatcher, which was discovered in 1861.These meteors can sometimes produce bright dust trails that last for several seconds.

The crescent moon should not be too much of a problem this year. Skies should still be dark enough for a good show. Best viewing will be from a dark location after midnight. Meteors will radiate from the constellation Lyra, but can appear anywhere in the sky.

April’s New Moon will occur April 26 at 12:17 UTC or 7:17 AM CDT. This is the best time of the month to observe faint objects such as galaxies and star clusters, as there will be no moonlight to wash out the evening sky.

Evenings in early April offer an excellent opportunity to view the zodiacal light. Zodiacal light is a faint, roughly triangular whitish glow seen in the night sky which appears to extend up from the vicinity of the sun along the ecliptical plane. It is caused by sunlight scattered by space dust in the orbital plane of the Earth.

From the Northern Hemisphere, early spring is the best time of year to observe this elusive glow after sunset. It appears slightly fainter than the Milky Way, so you’ll need a clear moonless sky and an observing site located far from the city. Look for the cone-shaped glow, which points nearly straight up from the western horizon, after the last vestiges of twilight have faded away.

This is the time of year when the dim Little Dipper – Ursa Minor – juts to the right from the North Star, Polaris, which is the end of the Little Dipper’s handle, during late evening. The much brighter Big Dipper curls over high above it, “dumping water” into it. They do the reverse in the fall.

Now that it’s spring, the signature fall-and-winter constellation Cassiopeia is retreating down after dark. But for mid-northern latitudes Cassiopeia is circumpolar, never going away completely. Look for it fairly low in the north-northwest these evenings. It’s standing nearly on end.

Cassiopeia, lying directly opposite of the Big Dipper, is a valuable navigation tool, in that if the Big Dipper is not available to locate the North Star, being obscured by clouds or terrain, you can use Cassiopeia, which is shaped like a rough “W”. Draw an imaginary line from the center of the “W” and the first bright star you run in to is Polaris.

Orion is also valuable as a rough navigation aid as the two left stars forming the elongated square forming Orion always lie on a general north / south line, and the bottom two stars of the square lie on a rough east / west line.

Also there is the “LURD Method”. An acronym for “Left, Up, Right and Down”.

If you pick a bright star fairly high in the sky, note its position and then look at it again some minutes later, if it has moved left, you are facing North. If up, you are facing East. If right, you are facing South. If down, you are facing the West.

The moon can give you clues too, as it will move West and with a crescent moon, the horns will align roughly North & South.

For years, ALERT has had a newsletter, and for ALERT Operational Members a callout text message/email list. This month, and into April, we will be making calls to phone numbers on the callout list, to make sure that we have up-to-date information on our members who respond when called to the National Weather Service.

 In 2012, we lost some information in a server upgrade, and as recently as 2016, we realized that if a message ever bounced, the server was removing people from the list, without us knowing it. Today, Microsoft has donated us email server services, through Office365, which fixes those issues. 

If you were previously on our newsletter list, and found yourself removed, or you wish to subscribe, please send an email message to admin {aT} alert-alabama.org OR to our Facebook page (facebook.com/K4NWS), and include the following information.

  • Your Full Name (and/or callsign if a ham radio operator)
  • Your email address

If you are an Operational Member, and you wish to be on the callout list for email or phone, send an email message or Facebook message with:

  • Your Full Name (and/or callsign)
  • Your email address
  • For text messages, your phone number and cell phone carrier
  • You will also receive an invite to access the members-only area, in Office365 Sharepoint.

ALERT does not share your information outside of the NWS/ALERT, and will not sell your information to commercial interests.

Hi Everyone,

Water Purification Changes With New Version Clorox
Water contamination or shortages can occur for many reasons, and is not as uncommon as you may think. The causes for these shortages can range from natural & man-made disasters, industrial accidents to the more mundane occurrence of a guy having a bad day with a backhoe.
Many guides recommend using chlorine bleach for water purification, which is indeed one of the best methods available. However many of these guides were written before Clorox began offering the new Concentrated version of Clorox, and this new version requires a different mixture or amount needed for water purification.
The following, courtesy of Clorox®, details how to use both Clorox Regular-Bleach and New Concentrated Clorox Regular-Bleach for emergency disinfection of drinking water.
Prior to addition of the bleach, it’s important to remove all suspended material from collected water by letting it settle to the bottom or by filtration. This means that after you collect some water that hasn’t been treated, you need to let it sit long enough to let any debris settle to the bottom of the container.
Next, decant the clarified contaminated water into a clean container, then add the bleach. Use the table below to determine how much bleach to add—it depends on how much water you are treating.
Allow the treated water to stand for 30 minutes. Properly treated water should have a slight chlorine odor.
If there’s no chlorine odor, then you need to repeat the treatment. Just add the same amount of bleach, and wait for another 15 minutes. Check again for the chlorine odor before drinking the water.
Amount of Clear Water Amount of Clorox® Regular-Bleach Amount of New Concentrated Clorox® Regular-Bleach
1 quart 2 drops 2 drops
1 gallon 8 drops 6 drops
2 gallons 16 drops 12 drops, or 1/8 teaspoon
5 gallons 40 drops 30 drops
Here are some other important things to remember.
ONLY use Clorox® Regular-Bleach or new Concentrated® Clorox Regular-Bleach. DO NOT use the Scented bleaches, High Efficiency bleach Splash-Less bleach, Ultimate Care bleach, or the Bleach Pen.
Use bleach that was purchased in the last 4 months.
If the water you want to treat is cloudy and you can’t decant or filter it, add twice the amount of bleach recommended above.
Check with your water service provider to confirm that your tap water is safe to drink.
If you stocked up on bottled water, save the empty bottles!! You can use some of them to collect untreated water, and others to store the water you treat.
More information on water purification during emergencies may be seen on my article “The 5 Main Ways To Push Up Daisies In A Disaster Part 3” which was featured in the April 2013 Newsletter.

This was part of a multipart series, basically a mini survival guide which I ran from March to June 2013, of which, I’ve toyed with the idea of updating and rerunning. IF there is interest

Mark’s Almanac

Originally called Martius, March is the third month & first month of the Roman calendar. March is named for Mars, the god of war, and was the start of the military campaign season.

The beginning of “Meteorological Spring”, which is based on changes in temperature and precipitation, not the solar angle, is March 1

March is a wet month. Most floods occur in March and rainfall averages around 6 inches.
Tornadic activity sharply increases in March with there being an increase of 2.2 times the number of tornadoes over the February amount. The focal point for this tornadic activity is the Gulf States.

March is the hail maximum for the Deep South. This is due both to the number of thunderstorms & due to the freezing level still being near the surface. This allows hail to form at lower altitudes and reach the ground intact, as opposed to summer months, when the freezing level is higher and near surface level temperatures are higher melting the hail into liquid before impact.

Killing frosts are gone and the last average frost is on March 16.

March is a snow month for Alabama & there is a 45% chance of snow up to one inch, and an 8% chance of one inch or more.

The good news is that there is hope on the horizon as Spring will arrive at Vernal Equinox on March 20 at 10:29 UTC or 5:29 A.M. CDT.

The Sun will shine directly on the equator and there will be nearly equal amounts of day and night throughout the world. This is also the first day of fall, or Autumnal Equinox, in the Southern Hemisphere.

Remember to get the eggs out, as it is said that you can stand eggs on their ends at the hour of equinox.

Daylight Savings Time begins at 2 AM on March 12. So remember to “spring forward” one hour. This, of course means I will lose one hour of “beauty sleep”, which is something I desperately need.

Saint Patrick’s Day is March 17, and you better participate by wearing a Touch O’ The Green or you will be plagued by leprechauns and gnomes. Not a pleasant experience, I can assure you.

Looking towards the sky, Mercury, is hidden deep in the glare of sunrise. He will move behind the Sun and then reemerge into the western sky and by the end of the month he will reach his highest point in the sky, or “Greatest Eastern Elongation” on April 1. At that time the planet will be 19 degrees from the Sun. This is the best time to view Mercury. Look for the planet low in the western sky just after sunset.

Brilliant Venus, magnitude -4.8 in Capricorn, is near peak brightness, the southwest during and long after twilight.

In a telescope Venus is a crescent, thinning in shape, but, growing larger in the telescope week by week. It’s now about 25% sunlit. For the rest of the winter, as Venus swings toward us, it will continue to expand as its phase wanes down to a super-thin crescent.

Venus in a telescope is least glary when viewed in bright twilight. So get your scope on it as soon as you can see it naked-eye, even before sunset.

Mars, magnitude +1.2 in Aquarius, glowing in the south-southwest at dusk, is the faint reddish “star” upper left of brilliant Venus, but, only 0.4% as bright.

Jupiter, magnitude -2.3 in Virgo, rises around 9 or 10 PM and glares highest in the south in the hours before dawn. The star Spica dangles not quite 4° lower right of it after they rise, more directly below it in the early-morning hours, and lower left of it in early dawn as shown above.

Jupiter is creamy white, while, Spica is an icier shade of white with a trace of blue, once it’s fairly high in the sky.

Spica will be twinkling, while Jupiter will not.

Saturn, magnitude +0.5 on the Ophiucus-Sagittarius border rises in the early morning hours and glows in the southeast before and during dawn.

Uranus, shining at a borderline naked eye brightness of +5.9 in Pisces, is still in view in the southwest right after dark, in the background of Mars. The two planets will pass 0.6° from each other on the evening of February 26th.

Neptune is lost in the glow of sunset.

Full Moon will occur on March 12 at 14:54 UTC or 8:54 AM CST. This full moon was known by early Native American tribes “Worm Moon”. So called because the rains disturb the earthworms & they are seen wiggling around after the rains.

They are edible by the way, but I think I’ll let you have my share. Incidentally slugs are edible also. Just think of them as snails without the shell

New Moon will occur March 28 at 2:58 UTC or 8:58 March 27 PM CDT. The Moon will be located on the same side of the Earth as the Sun and will not be visible in the night sky. This is the best time of the month to observe faint objects such as galaxies and star clusters because there is no moonlight to interfere.

Celestial carnivores are emerging from hibernation. After dinnertime at this time of year, five carnivore constellations are rising upright in a ragged row from the northeast to south. They’re all seen in profile with their noses pointed up and their feet (if any) to the right. These are The Great Bear, Ursa Major in the northeast, with the Big Dipper as its brightest part, Leo the Lion in the east, Hydra the Sea Serpent in the southeast, The Lesser Dog, Canis Minor higher in the south-southeast, and The Greater Dog, bright Canis Major in the south.

Sirius, shining at magnitude −1.46, the brightest night time star, blazes high in the south on the meridian, in Canis Major by about 8 or 9 p.m. Using binoculars, you will find a fuzzy spot 4° south of Sirius, directly below it when directly South. Four degrees is somewhat less than the width of a typical binocular’s field of view.

That dim little patch of gray haze is open star cluster Messier 41, a small gravitationally bound group of 100 stars about 2,200 light-years away, and moving away from us at 869 miles per second. Sirius, by comparison, is only 8.6 light-years away.

Canopus, the second-brightest star after Sirius, lies 36° almost due south of Sirius. That’s far enough south that it never appears above the horizon if you are above latitude 37° N, such as southern Virginia, southern Missouri and central California. Luckily we lie south of that latitude, with our horizon lying, in the case of Central Alabama, around latitude 33°. So give Canopus, which crosses low above the horizon, due south just 21 minutes before Sirius does, a peak.

3449 planets beyond our solar system have now been confirmed as of February 9, per NASA’s Exoplanet Archive http://exoplanetarchive.ipac.caltech.edu/
