Yeah I mentioned last night how that ULL was making a run SSW hard last night and expected it to be S of Cuba by midday but it turned around ??


If anything I think the ULLs to its SW and the one to the north retrograding westward with it is helping pushing the northerly shear that is over the central GOM towards the west out of the way of Gordon as clearly seen below compared to 24 hrs ago. Its fast westerly motion is what's preventing currently from strengthening any further in the short term, is having a hard time getting a nice inflow, IMO.


The one to the SW I would bet is causing the W movement some I think? it was Claudette that made a L/hook in the GOM into TX over and around the ULL.This has been a year with alot of ULL about.


To some degree the ULL might be causing a more westerly heading the last few hours but the real corporate is the strong east to west low to mid level jet across the northern GOM, check out tonight's Tallahassee sounding, east winds from the surface all the way up to h40!

HRRR @ 00z makes it to Jackson Co. landfall around 10pm. Nudges Baldwin and Mobile Counties so you’d think if you were on Dauphin Island, you’d encounter close to TS conditions.

With it falling apart right now, the possibility of it going further West is greater, if I'm not mistaken.

:uarrow: Yep definitely exposed now. Makes you wonder if the GFS and EURO are correct regarding intensity.

These small systems have fluctuation with their intensity. It's going to be a rollercoaster ride.

Wouldn’t be surprised to see the COC relocate farther to the east

Yep. I’ve seen many storms look like they’re about to die and then hit the right environment and blow up

Per the recon's latest pass it looks like the COC is near 26.8N & 84.1W

55 knot flight level winds on the northern quadrant.

Holding steady really. Until it can wrap deep convection doubt it does little strengthening.
