One of my favorite stats, and from my locale, is that there has never been a major hurricane strike in Texas (Cat 3 or larger) after 30 September. 

Still October and November can still get kind of dicey for our FL Briefer friends.

I keep hearing about an Atlantic Nina that has waters cooling earlieir than normal. 
Plus the Gulf waters up my way are cooling.  The water is only "Bath" temps now!   lol
You don’t become cooler with age but you do care progressively less about being cool, which is the only true way to actually be cool.

This has been a rough hurricane season for FL and NC. 

I found the article below very interesting and yes Milton was predicted with some accuracy, but people truly need to realize that most of the time you don't know where the hurricane is actually headed until it is pretty much on top of you and too late to do anything at the last minute.  AI assisted hurricane predicting is fine, but at the end of the day God decides where Mother Nature is going to strike and hurricanes ARE unpredictable and can turn at the very last minute. 

Interesting that they rely heavily on past historical data.  That indicates to me, that hurricanes and their patterns are cyclical not based on climate change!

Hurricane Milton's Path Predicted With 'Unbelievable Accuracy'—Here's Why

A weather model driven by artificial intelligence has stunned meteorologists by predicting Hurricane Milton's landfall within 7 miles on average—outperforming traditional models by almost 100 miles.

Artificial Intelligence/Integrated Forecasting System (AIFS) forecast Milton's landfall location within 7 miles of the actual point, five days before it hit Florida near Siesta Key. Other leading models' maximum errors were up to 100 miles from landfall, while AIFS' maximum error didn't exceed 13 miles.

"While it is difficult to draw conclusions from one case, it seems like AIFS provided somewhat better track forecast for Milton one to two days before landfall. From October 2 on, the AIFS consistently predicted that Milton would make landfall in Florida," a spokesperson for the AIFS team told Newsweek.

Writing on X (formerly Twitter), Bryan Bennett, a meteorologist who closely monitored the storm, described the model's "unbelievable accuracy." He emphasized the model's early and precise predictions: "It predicted a landfall near Siesta Key more than five days in advance. The model knew that it wouldn't make landfall in Pinellas County or anywhere else in Florida."

Bennett noted that the advanced weather model has consistently delivered precise forecasts for other storms this season, including Hurricane Helene in September. "This is the future," he wrote. "Modelers are likely taking notice and will attempt to hop on board the AI weather modeling in the coming years."

AIFS stands for Artificial Intelligence/Integrated Forecasting System, a nod to ECMWF's well-known Integrated Forecasting System (IFS).

In 2017, the IFS model accurately predicted the path of Hurricane Irma about a week in advance, the 2019 heatwave in Europe, and the conditions that contributed to the bushfires in Australia in 2019 and 2020.

Unlike traditional numerical weather prediction models that rely heavily on physics-based equations, AIFS uses machine-learning techniques.

The model is trained on decades of weather data, allowing it to recognize complex patterns and relationships in atmospheric conditions. This enables it to generate forecasts rapidly and with significantly less computational power compared to conventional models.

The AIFS team spokesperson told Newsweek that they are currently training the model on historical reanalysis but that "the magnitude of extremes (i.e., tropical cyclone intensity) is limited by what can be captured by the reanalysis."................

Excellent....  I have said a few times that i have been very impressed with the GFS all season long.  OTOH, SHIPS, among others have been less than stellar in strength predicition.  In some ways I feel that the NHC got flat-footed on Milton and Helene.  And in the case of Milton, a wobble or a slight northward jaunt at the end would have had some serious consequences for Tampa. 

Telling an effected coastal community whether they are going to see a Cat 2 vs. a Cat 4/5 is a massive diffeence.

New Tropical Storm, Rafael headed into the GOM.  Will brush the keys and is not expected to be a strong storm when it makes landfall in LA.

Been distracted, but the GOM has chillled very well after 3 or 4 strong cold fronts.  I am guessing this is going to be a bigger rain maker, than a wind generator or surge problem.

Fledgling Sara storm could rapidly intensify into a major hurricane, threaten Florida

Hurricane Sara could form as early as this week, according to a new report from AccuWeather, and could threaten Florida.

Recent data from the National Hurricane Center place the chances of Tropical Storm Sara developing up to 60% over the next 48 hours and 90% over the next seven days.

“We’ll likely be dealing with a hurricane as we head into this weekend. There is increasing confidence that a tropical storm will develop in the central to western Caribbean later this week,” explained AccuWeather Lead Hurricane Expert Alex DaSilva.

“We could be dealing with a storm that rapidly intensifies into a major hurricane in these very conducive conditions. The atmosphere is primed for development.”
Central and western Caribbean tropical wave has the potential of developing into Tropical Storm Sara.............

The trusty GFS which has worked like a charm has it as powerful as a 941Mb as it reaches the Yucatan Channel on or about the 18th.  (Low End Cat 4).  The GFS then turns the storm northward and eventually northeastward towards the FL Big Bend area.  The good news is that is the GOM has seen a lot of fronts, and has cooled significantly.

If the GFS can be believed, and I really don't see a major cane holding together in these water temps....   It ends up being about a 960Mb hitting FL on or about the 20th, as a low end Cat 3...   Yes as a major hurricane.  So from my experience I tend to believe that this run is over aggressive in strength.....  unless this future storm compacts, stays tight, and can fight off the cold water and sheer that is typical for this time of the year.

Or...  as Accuweather states....  Takes a western track, which would be indicative if the storm stays at lower latitudes, and avoids the CONUS troughs and fronts all together.

GFS has gone mad.  Today's run has even a stronger hurricane that hits the Yucatan Penn on about the 14th as a CAt 4.  Ventures up in the central GOM for about a day, and then takes a sharp right turn toward the FL Keys.  Reaching the keys about the 20th as a Cat 2.

But, take a lot of this with a grain of salt at this point, as evidence in the 700 mile path variation since yesterday.  FL residents just need to keep one ear on the weather radio the next few weeks.

Latest local weather shows it hitting the Yucatan peninsula with it then heading into the GOM and the consensus spaghetti model shows it right now eventually heading smack dab into the Naples/Ft.Myers area.   Local weather expert is certain that this is going to strengthen into a hurricane.

I had forgotten about Sara - local weather predicted we'd get some rain, but notta drop.

Big Cold front moving on in right now. I think we can put a lid on the 2024 'Cane season.

A change of air masses could mean more coastal storms for Northeast.

2024 has been the dryest Fall (Sept. 1 - Dec. 1) on record.  We are experiencing drought conditions and wildfires in Greater Boston.  This is normal in Spring but uncommon in Fall.

Most of the major storms have been shunted west, south, and north of Southern New England.  We've only been getting cold fronts that dry up by the time they reach eastern Mass.

The annual average doesn't look that bad because we got drenched in late Winter and in Spring.

The end of November signifies the end of the official tropical hurricane season.  If conditions are right, New England could get subtropical or extra-tropical hurricanes.  Some major blizzards have been informally classified as white hurricanes.

Yes, the mighty GFS ends the season with a whimper. 

But...  October and November hurricanes are the extremely hard to predict due to the fronts and troughs that dig south that time of the year.  Plus, the interaction with some of these accompanying lows with fronts can interact with the triopical systems   A 995Mb  frontal low versus a 998 can not only impact strength, but the cascading isobars, can add another degree of deflection of storm direction.

What crybabies.

Many a storm has "bombed out" around New England.  Yeah, there's wind, rain, coastal flooding, damage, blakouts, etc, but thems is the breaks for living alongside the Northwest Atlantic Ocean.

- Prepare to lose electricity, water, and heat.
- Fill the bathtub in case you lose water.
- Have batteries and a generator for blackouts.
- Stock up on non-perishable foods, medications, pet supplies, and health and beauty supplies.
- If the outside temperature drops below freezing, keep room doors and cabinet doors open to resist freezing pipes.
- Have books, playing cards, and board games handy to fight off boredom.
- Fill up your cars and gas tanks with gasoline / fully charge your EV's.
- Have a go-bag with important documents ready in case you have to evacuate.

Don't fret, my West Coast hippy friends.  Think of it as involuntary camping trip.

@DefiantMassRINO   A lot of good advice there, anywhere in the USA.  People, fill your pantries no matter where you are.  In my Castle, we have overflow space.

I don't know what all that means.  What I do know is when the gulf cools and we get a nice cold front with cool winds blowing from the north I feel safe in the knowledge that a Nov Cane will be snuffed out.
