12z HWRF Animation

Looks ok on intensity (TS) ,not the monster that GFDL has.Tracks thru the Yucatan Channel.

It would surprise me more if this disturbance were to develop into a tropical storm or hurricane then if it were not to.
Most of the models (except the CMC) are backing off from anything significant developing so that just adds more wood to the fire. But as I always say in the tropics anything is possible. IMO

ECM still develops a system and moves it into the Gulf after hitting the Yucatan...

Actually stormcenter, its the other way round, most models are slightly more bullish today then they were yesterday, the GFS/CMC/GFDL/HWRF/ECM/NOGAPS all develop at least a TD/weak TS though very few go beyond that sort of strength, but most do develop something weak in the W.Caribbean/Gulf.

12z rundown of models is certainly stronger today

It seems though the euro develops the panama low, not really 93l

ECM only weakly strengthens the system in the Caribbean, most of the strengthening occurs in the Gulf, system heads north, then has the door closed on it so to speak before the upper high shifts eastwards over the states and the system comes northwards again towards landfall at 240hrs.

Ivanhater, trace back to 24hrs time, weak system just south of Jamaica which heads westwards...

No 18z run of the BAMS yet. I guess they are trying to pinpoint a circulation to then start the run or they may wait until the 00z time.

You go to love the ECM for the "entertainment" factor sometimes especially when you consider that far out (240 hrs).
I'll never forget the two major hurricanes it had hitting N.O. one after another from the east a couple of seasons back. Anyway there are some factors (possible shear) this may have to deal with if it were to make into the GOM that the models always have a hard time picking up on. IMO

I'm sure it has already been said, but I will say it again. Until the models have a good LLC to latch on to they are going to continue to be all over the place with widely varying intensities as well. We've seen this over and over.

Looks like the models are becoming increasingly confident of a Yucatan landfall. I'd think thats looking quite likely now given most of the models are too far north and east right now.

Also raises the chances of a 2nd landfall possibly in Mexico rather then Texas...though the track to the NW is a logical one as well...
