Another look at the storm striking South Florida in 288hrs. on the 18z GFS. Hopefully this is just a Halloween trick by the GFS.

18z develops this at hr 180 and it as seen in the pic landfalls in Florida at 288 so a slow mover which would fit climatology

00z GFS is spitting out quite a few vortices (it's not as consolidated as the 18z run), but the components from the 18z run and time frame remain the same:

massive BS on the GFS. Cannot understand how this model was ever made operational.I'd take the Kain-Fritch convective scheme over this garbage

00z GFS at 288 hours:
It's the CMC, but it may have a more realistic scenario. System tries to develop along the frontal boundary that pushes through the SECONUS into the Caribbean, and essentially becomes stretched out and absorbed:

Folks,
The threat for a TC genesis during 10/24-29 in/near the NW Caribbean continues to increase. There are no fewer than 7 of 20 members of the 0Z GEFS with a H and most members with a TS+. One H hits S FL 10/30. Several TSs hit FL and several Hs lurk in the NW Caribbean at the end of the run. No, this isn't quite as active as the often most active 18Z GEFS but it is much more active than any non-18Z GEFS for late Oct.

Meanwhile the 00z Euro shows nothing through 10 days.

6z GFS still with a signal but jumping L pressure all over the place. Nothing organized.

00Z CMC very similar to 6z GFS and 00z EURO nada. So overnight and early morning models back off.

For typically having been the quietest GEFS run of the 4 in week 2 at least in recent weeks' runs, today's 6Z GEFS is relatively active with ~13 of its 20 members becoming a TS+ and 6 becoming a H. Most geneses are 10/27-9. One TS hits LA 10/31 while two Hs hit (1 W FL and 1 Keys/S FL) 11/1 with another hitting the Keys 11/2.

Not really. If you step back and take a look at the past few days plus factor in the ensembles (GEFS), models are actually showing an increased chance of development in the Western Caribbean. Plus the CMC and GFS show development but show interaction with a strong cold front preventing significant development. Whether that really happens is not clear or not yet, i.e. just how strong will this cold front be as we are still in the long-range?

Gatorcane, glad you mentioned the cold front issue - even though the models might indicate development, that late in the season the polar jet is forcing fronts south of 30N every 3-5 days, so whatever does form if it does, will be influenced by a front. Wilma as we know was influenced by a front, and actually became ST immediately after crossing Florida, so a lot more to consider than just a month earlier...

So indeed lets hope nothing develops considering it will more then likely be drawn towards FL. This season has had way to many unexpected surprises to say the least.
