That could be, one of local forcasters here in Jacksonville said as that cut off low, moved west it would seal Dean on a southern route keeping Florida free of Dean.
I don’t see Dean hitting Florida (except for possibly some effects on the far west Panhandle, and even that seems doubtful). But the low, if it drifts into the Gulf and does not dissapate, could help “pull” Dean further north. It looks like the GFDL is believing that will be the case. I seriously, SERIOUSLY hope the GFDL is wrong. At this point, best case is a strike well to the south of Cozumel.
