Absolutely. I'm less inclined to think that Erika will survive marginal conditions all the way to the Florida coastline, but muster enough deepening to manage a borderline hurricane, as I am to either see:
1) complete dissipation, if conditions become that much more unfavorable OR
2) slow overall intensification and organization over time with even greater intensification beginning north of Hispanola or E. Cuba where SST's get a good deal warmer and present 200mb charts would indicate an upper anticyclone to be over the region, thus resulting in a Cat. 2 Western Bahamas or S. Florida landfall. If pressed to guess, i'd say landfall between Ft. Lauderdale and Ft. Pierce

Just as important may be exactly how strong the ridge will be, thus causing hurricane impact to a much larger area of Florida. It appeared to me that the ridge only continued to build in further with time, thus the slower Erika were to move the even greater likelihood of not feeling any hint of residual weakness off the coast of Florida. Short of another collapse of convection tomm., this event is about to start getting a lot more real.

Towards Florida. Not necessarily into the Gulf, but that ridging is looking stout enough to where it's not crazy (it's actually fairly plausible) that the storm gets pushed out into the Gulf.

I'm sorry for my lack of knowledge, but what are stockers?

After hitting SE Florida where does both the Euro and the HWRF have
Erika going? Across the state or up the east coast?

Euro runs up the state and stalls over N-Central Florida. Eventually it gets pushed southwest into the Gulf (way out at 10 days). The HWRF ends with the center just making landfall, but the storm would likely continue into the Gulf at least a little ways on that path; the direction shifts from WNW to almost due west in the last few frames.

GFS not caving to the Euro or HWRF...stil with a weak reflection at 96 hours just north of Cuba.

Stayed up for GFS run--it seems to be having some serious initialization trouble, it's starting out a tad south of the actual position and as a depression, while recon indicates it may be as high as 50mph. Makes me wonder if the previous missions were even input into the model to start with.

I just want to point out how silly it was for those writing this storm off as a fish storm a few days ago. Now remember, this is still ~5 days away from a potential U.S. landfall and tracks can change further. Also we have to be concerned about our friends in the Antilles and Bahamas. Erika definitely deserves close attention, and the recent trend in the model guidance is concerning. Those in the path of the storm should have already had their hurricane supplies ready just in case. There is no need to freak out, but be prepared!!!

Pretty good model consensus for 5 days out. Look for trends now - IMO if there are changes they're likely to be slight shifts west as the ridging might be slightly stronger than advertised now. I wouldn't discount a GOM track now as I think it has equal validity with some of the more eastern paths. Oh and someone mentioned not liking the up the spine path? Actually would probably be the best situation for Floridians if it stays as forecast as a CAT 1 as it would quickly drop to TS storm strength and winds won't be that great of a factor. Heavy rain on the other hand, while welcome in S FL, would cause major problems for us in the Tampa Bay area as we're brim full with several of our rivers at or near flood stage already (i.e. Hillsborough, Peace, Withlacoochee, Alafia).

That Euro run can bite it, that loopback off St. Augustine to Tampa means it could also stall over the state. Pretty much all of Florida (non-Panhandle) gets affected.

I didn't see anybody asking this. It appears that the Euro has this riding up the spine of Florida exiting around Jacksonville and then riding back thru Florida and exiting around Tampa. Is that a realistic scenario? That would inundate basically all of Florida with rain for over 5 days.... :double:

Did anyone notice the end of the Euro run,Erika gets trapped by a building high and gets pushed SSW back into the GOM.
