Re: Dean

Many thanks to Mike with the help on mirroring the images. I hope they are of some use to you guys, being more complete than the SFWMD images (and a bit better looking, I think). The full set of images can always be found at http://moe.met.fsu.edu/~acevans/models/ -- including GFS Ensemble model tracks and a "quick look" image showing what is being plotted.

With respect to the tropics...
The structure of Dean, as illustrated by QuikSCAT, is such that as it moves into a region of weaker easterly shear, better thermodynamics (away from all of that stable air near the Cape Verdes), and warmer SSTs, it has a chance to develop at a decent rate. Look for this to happen starting sometime tomorrow -- probably afternoon into evening.

Not a whole lot to change with respect to the forecast reasoning or intensity right now. The NHC track and intensity both look reasonable at this time. From there, it's still largely a crapshoot, but a major hurricane is likely to be somewhere in Hebert's box before the 5 day period is out.

And TD 5? For some reason, I'm getting Dean flashbacks in my mind...except from the 1995 version rather than the 2007 version. What that means is a weak to moderate storm making landfall on the Texas coastline a day or two after it developed with rainfall as its most significant effect. The NHC intensity and track look good, though there's an outside chance at more intensification than anticipated depending upon how much the shear relaxes. The warmest (and deepest) waters of the Gulf are further east, so don't expect a bonanza out of this one.
