Hi everyone and welcome to the October ALERT Newsletter.
Fall has arrived and with it we can look forward to the changing of the fall leaves, the occasional nip in the air, and perhaps Hobgoblins visiting us at the end of the month.
October is a fun time of the year, usually being not too hot and not too cold – the “Goldilocks” of seasons.
It is a time to enjoy fall football, the baseball playoffs, of which my Cubbies have a 4% chance of reaching, and the last outdoor adventures of the year.
Here is hoping that you safely enjoy the days that this season and the pretty weather October brings.

Birmingham NWS Fall 2023 Spotter Courses
The Birmingham NWS will be offering several online and in person Basic and Advanced Spotter Courses this fall. These classes are FREE and allow individuals to complete these courses in the comfort of their own home or office as well as in a traditional format.
By attending any course, which runs about 2 hours, an individual or a group of individuals will become SKYWARN Spotters.
Unless you want to or are in need of a refresher, you do not need to attend more than one Basic SKYWARN Course, as the material covered is the same; however, it is required that you attend at least one Basic SKYWARN Course before taking the Advanced SKYWARN Course. These courses are two-way, meaning you will be able to interact with the meteorologist leading the training. You will be muted while training is in-progress, but you may use the built-in chat feature to ask questions.
To attend the Online Spotter Class:
1. Via the schedule below, register by clicking the link
corresponding to the class you’d like to attend.
2. Select the ‘join webinar’ button on the registration page or
in your confirmation email and follow the prompts.
3. Enjoy the class and ask questions.
To avoid being hurried, give yourself at least 15 minutes prior to the start of the class to complete the above process.
The current schedule is as follows:

These classes will help you provide the NWS the vital “ground truth” information they need to verify radar indications, target their attention and help you relay reports in a clear manner to the NWS, either directly via 205-664-3010 and pressing 2, online at https://www.weather.gov/bmx/submitstormreport
or via chat or amateur radio. This knowledge helps Skywarn Net Control stations filter reports, by giving them knowledge of what reporting stations are trying to describe. This way they can tell if the report is a valid report, an invalid report by an overly excited operator or a valid, but poorly described report, which without this knowledge would be mistakenly dismissed.

Mark’s Almanac
The tenth Month, October is so named because it is the eighth month on the Roman calendar. To the Slavs of Eastern Europe it is called “yellow month,” from the fading of the leaves, while to the Anglo-Saxons it was known as Winterfylleth, because at this full moon (fylleth) winter was supposed to begin.
By whichever name you call it, October is a mild and dry month, the driest of the year, in fact. And it is a sunny month with the amount of possible sunshine reaching the ground in the 60% or greater range.
Weather shifts from autumn pattern to revisiting the summer pattern and back again. The Azores-Bermuda High shifts eastward into the Atlantic, but leaves weakened high pressure centers over the Virginias, which still try to block out approaching fronts.
October is usually a quite month for tornadoes, with a 40% decrease in activity. Nationwide an average of 28 tornadoes occur in October and those tornadoes are usually weak.
Our Hurricane threat continues, with hurricane activity increasing during the first half of the month, concentrating in the Caribbean, both from formation in the Caribbean and from the long track Cape Verde hurricanes, which enter the Caribbean. And, we still have the little “gifts” that the Gulf of Mexico occasionally will provide.
Florida, due to its low latitude, becomes especially vulnerable to hurricanes. Since 1851, Florida has endured 31 October hurricane landfalls, nearly triple the next highest state — Louisiana, which has had eight. Also, about 60 percent of all U.S. hurricanes that made landfall after September 26 have done so in Florida. One factor being the cold fronts of Fall penetrating the Gulf and then deflecting storms towards the West coast of Florida.
Luckily after the second half of the month the activity will begin a steady decrease.
28% of the year’s hurricanes occur in October.
From 1851 – 2022 there have been 365 Tropical Storms and 218 hurricanes, 60 of which made landfall in the United States.
Some notable October hurricanes are:
The Great Hurricane of 1780, also known as Huracán San Calixto, the Great Hurricane of the Antilles, and the 1780 Disaster, the deadliest Atlantic hurricane, which killed between 20,000 to 22, 000 people in the Lesser Antilles as it passed through from October 10 – 16, 1780. It is possible that it had winds in excess of 200 MPH when it reached Barbados.
Hurricane Hazel struck the Carolinas in 1954. Weather satellite did not yet exist, and the Hurricane Hunters were unable to observe the core of the storm until it neared land on October 15. Hazel made landfall just west of the North Carolina/South Carolina border slightly northeast of Myrtle Beach, South Carolina with a Category 4 intensity of 130 mph.
Hurricane Wilma still holds the record as the most intense tropical cyclone ever recorded in the Atlantic Basin. In 24 hours, Wilma went from a Category 1 storm on October 18 to a Category 5 storm with 185 MPH Maximum Sustained Winds. She weakened to Category 4 and struck the Yucatan, then restrengthened and struck Cape Romano Florida as a Category 3 storm on October 24, 2005.
Hurricane Mitch became a Category 1 hurricane on October 24, 1998, and within 48 hours grew to Category 5 intensity, and though he weakened to Category 1 before making landfall, he became the second deadliest hurricane on record killing over 11,000, with nearly that number missing in Central America due to intense rainfall and mudslides. He would eventually reach the United States making landfall near Naples Florida on November 5.
Hurricane Michael formed near the Yucatan Peninsula on October 7, 2018, and in 72 hours grew from a Tropical Depression to a Category 5 hurricane striking struck Mexico Beach Florida.
Beware of October hurricanes, for as Wilma, Mitch and Michael have demonstrated, they can experience explosive growth.
October Tropical Cyclone Breeding Grounds
This is the month for Alabama’s version of “Indian Summer’s” arrival.
Technically speaking Indian Summer doesn’t occur until “Squaw Winter” or the first frost arrives, but exact date when Indian Summer arrives varies with latitude.
We live in Alabama, and while the earliest frosts have been known to occur by October 17, they usually wait until November. So, we, in our milder climate call the first warm up after the first cool down “Indian Summer”.
The Yellow Giant Sulphur Butterflies are very noticeable as they continue to drift South-Southeast on their migration towards Florida. They prefer red things & if you have red flowers, they will zero in on them.
The Monarchs also will be seen gliding by in their migration towards Central America.
Fall colors will become prominent & by late October & early November the leaves will be reaching their peak fall colors.
Days rapidly grow shorter as the Sun’s angle above the noonday horizon steadily decreases from 53.2 degrees at the beginning of the month to 42.3 degrees at the month’s end. Daylight decreases from 11 hours 50 minutes on October 1 to 10 hours 51 minutes on October 31.

There are 1,312,822 known asteroids as of September 27, 2023, per NASA.
5523 planets beyond our solar system have now been confirmed as of September 20, per NASA’s Exoplanet Archive http://exoplanetarchive.ipac.caltech.edu/.
Last Quarter Moon, or when the moon has only the Eastern side illuminated, will occur October 6 at 8:47 AM CDT or 13-47 UTC.
During a Quarter Moon the Moon’s magnitude is -10.0.
The Draconid Meteor Shower will peak on October 8 & 9. This minor shower, which produces only 10 meteors per hour, is produced by dust grains left behind by Comet 21P Giacobini-Zinner, which was discovered in 1900. This shower, which runs from October 6 – 10, is unusual in that it is best observed in the early evening, instead of the early morning hours as with most other showers.
The last quarter moon will be visible in the early morning but shouldn’t interfere too much. Best viewing will be in the early evening from a dark location far away from city lights. Meteors will radiate from the constellation Draco, but can appear anywhere in the sky.
The Moon will be at Apogee or its farthest distance from Earth on October 9, when she will be 251,920 miles from Earth.
New Moon occurs October 25 at 12:56 PM CDT or 17:56 UTC, when the Moon will 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.
An Annular Solar Eclipse will occur on October 14. An annular solar eclipse occurs when the Moon is too far away from the Earth to completely cover the Sun. This results in a ring of light around the darkened Moon. The Sun’s corona is not visible during an annular eclipse.
The eclipse path will begin in the Pacific Ocean off the coast of southern Canada and move across the southwestern United States and Central America, Columbia, and Brazil. A partial eclipse will be visible throughout much of North and South America.
In Birmingham the eclipse times are:
Partial Eclipse begins 10:38 AM
Maximum Eclipse 12:08 PM
Partial Eclipse Ends 1:42 PM
The Sun is never completely blocked by the Moon during an annular solar eclipse. Therefore, during an annular eclipse, it is never safe to look directly at the Sun without specialized eye protection designed for solar viewing.
Viewing any part of the bright Sun through a camera lens, binoculars, or a telescope without a special-purpose solar filter secured over the front of the optics will instantly cause severe eye injury.
See 2023 Annular Eclipse safety sheet at:
https://smd-cms.nasa.gov/wp-content/uploads/2023/09/2023-safe-eclipse-viewing-flyer-digital-download.pdf
The Orionid Meteor Shower peaks on October 20 & 21. The Orionids is an average shower producing up to 20 meteors per hour at its peak This shower, which runs from October 2 to November 7, is produced by the broad debris trail of Halley’s Comet.
The first quarter moon may block some of the dim meteors in the evening, but it will set shortly after midnight. This will leave dark skies for what could be a good morning show. Best viewing will be from a dark location after midnight. Meteors will radiate from the constellation Orion, but can appear anywhere in the sky.
First Quarter Moon, or when the moon has only the Western side illuminated, will occur October 21 at 10:29 PM CDT or 03:29 UTC October 22.
During a Quarter Moon the Moon’s magnitude is -10.0.
The Moon will be at Perigee or her closest approach to Earth on October 25, when she will be 226,722 miles from Earth.
October’s Full Moon will occur October 28. The Moon will be directly opposite the Earth from the Sun and will be fully illuminated as seen from Earth. This phase occurs at 3:34 PM or 20:34 UTC. This full moon was known by early Native American tribes as the Full Hunters Moon because at this time of year the leaves are falling, and the game is fat and ready to hunt. This moon has also been known as the Travel Moon and the Blood Moon. This full moon is also known as the Harvest Moon. The Harvest Moon is the full moon that occurs closest to the September equinox each year.
If there is a solar or lunar eclipse, there will be a lunar or solar eclipse within two weeks. Accordingly, there will be a Partial Lunar Eclipse on October 28.
A partial lunar eclipse occurs when the Moon passes through the Earth’s partial shadow, or penumbra, and only a portion of it passes through the darkest shadow, or umbra. During this type of eclipse, a part of the Moon will darken as it moves through the Earth’s shadow.
The eclipse will be visible throughout all of Europe, Asia, and Africa, and western Australia.
Southern Taurids Meteor Shower occurs October 29 & 30. The Southern Taurids is a long-running minor meteor shower producing only about 5-10 meteors per hour. This shower is, however, famous for producing a higher than normal percentage of bright fireballs. The Southern Taurids is produced by debris left behind by Comet 2P Encke. The shower runs annually from September 10 to November 20. It peaks this year on the night of the 29th and morning of the 30th.
Unfortunately, the Full Moon will wash out all but the brightest meteors. Best viewing will be from a dark location after midnight. Meteors will radiate from the constellation Taurus but can appear anywhere in the sky.
This is the time of year when the rich star clouds of the Milky Way in Cygnus cross the zenith, looking like a ghostly band overhead in the hour after nightfall is complete. The Milky Way now rises straight up from the southwest horizon, passes overhead, and runs straight down to the northeast.
Later at midnight, Orion the Hunter and the stars of winter rise over the eastern horizon, reminding us to enjoy the mild weather while it is here, for this season, as all seasons, is but a fleeting moment in the never-ending waltz of time.

This month’s meeting will be on October 10 at 7 PM at the NWS Forecast Office in Calera.
