Maybe not quite an M with the first advisory, but certainly a hurricane -- and Houston is currently the bullseye.


What is the strongest the NHC has ever forecast within 5 days on advisory #1?

My gut tells me that this may end up much further east than what is currently being shown. Based on visible satellite this thing is coming together really quick. I would think that if it develops sooner than expected it may go poleward earlier.

Maybe..... I don't see this getting any further east than the LA/MS border.

Since this won't most likely be classified until tomorrow, I won't be shocked to see them go with a Major at landfall since it will be a making landfall within 5 days. The NHC will put a M on their forecast if every single model continues showing that a Major will be making landfall.

Could be, but it would be unprecedented. Iota was only 72 hours away from landfall with big model support for at least a cat 4 and even then they didn't do it. Idk, I think they might go with 90 or 95 kt and wait for 1 or 2 runs after the system has consolidated. However, if there was ever a storm to go major on in advisory #1 this might be the one (if the models continue pumping out cat 3+).

Levi with the hot take. This would definitely play into the latest GFS run.

The tropics never cease to amaze me with how dynamic and quick changing things are. Two days ago this looked to be a slow moving Mexico system, now we are talking about it potentially being a faster central Gulf system.

Hopefully he's right because it would give it much less time over water thus making the storm more likely to be weaker than what previous model runs have been show.

Or the opposite could be said, earlier development stronger structure going into GOM, however I'M still not buying a M with the new runs kind of speek unless shear is nil the whole ride

Grand Cayman or Cuba would need a watch like now if anything did pop early.

I’m suspicious about how fast the 18z GFS run is when compared to everything else. As others have mentioned, that would rival Nate for the fastest GoM system ever recorded, and it’s such a deviation from the other models. I don’t know if any of the current steering factors could even produce such a high forward motion.

I am only a meteorology enthusiast who knows a decent amount about tropical cyclones. Look to the professional mets, the NHC, or your local weather office for the best information.

This should be PTC-9 sometime tomorrow morning if these trends continue. Watches and warnings could be required for parts of Cuba, Jamaica, and the Yucatán due to 99L passing near those locations within 48 hours of the 5am or 11am advisory times.

Not the GFS but look at 18Z HMON, Cat 1/2 by the time it reaches Cuba...
