943mb landfall. Maybe low end cat4

That GFS run is a bit too close to Tampa

The GFS like the Icon would likely be quite damaging well inland and probably all the way to my area and beyond. But as long as lexx gets the damaging storm she wants it is all good I suppose.

0Z UKMET: significantly stronger at landfall (likely sub 992 vs 1000 on 12Z run) and 150 miles east of 12Z with a landfall late afternoon Friday in the FL Big Bend moving NNE; thankfully not nearly as strong as Icon/GFS but UK is notorious for being conservatively weak this far out, especially with winds but also with SLP, and the stronger trend is worrying:

Even though the Icon and GFS have similar landfall locations/strengths, the GFS landfall is a whopping 60 hours earlier (Thu evening) vs Icon (Sun morning).

Yeah there are some crazy timing differences between models

0Z GEFS is still another pretty ominous run for Pensacola to Tampa and inland NE from there. Fortunately most members are much weaker than the operational but this is still not a good sign.

Euro is quicker and into Apalachicola on Thursday night

The 0Z Euro’s 989 at landfall is similar to the strength of UKMET/CMC and much weaker than the Icon/GFS MH with landfall Thu night (much closer to GFS’ Thu evening and UK’s Fri afternoon) than Icon’s Sun morning

GaWx · Sunday at 2:28 AM

0Z EPS: follows the faster and further E 0Z Euro but it is like the Euro still NW of the GFS suite with tracks centered on Apalachicola that then go N near the GA/AL line before curling back NNW. It is similar to the GEPS.
