Crankin' up the heat! Three storms now...

Okay. First things first. TD3 became a tropical storm yesterday afternoon and is now beefing up quite nicely. Satellite presentation is looking good. The shear vanished a lot sooner than expected and this has resulted in a significant boost in forecast intensity. As a result, it should reach hurricane status later today. This storm is called Bill, and it looks like the GFS was right yet again. It could reach cat 4 status by Thursday. Also, the GFS is still bringing it up the coast. The consistency is starting to get a bit worrying. The prospect of getting nailed with what amounts to a 1938 repeat is scary as hell at best. Current stats:

Location: 12.1N 38.4W
Moving: WNW @ 16mph
Winds: 60mph gusting to 70mph
Pressure: 997mb
Wind field radius-
TS winds: up to 140 miles

Next up is Ana. This one still looks very very sickly, and will likely get destroyed by Bill's outflow once it really gets cranking. There is a recon scheduled to investigate it later. I rather doubt they'll find anything worthwhile. Anyway, it's stats are:

Location: 14.8N 55.8W
Moving: W @ 24mph
Winds: 40mph gusting to 50mph
Pressure: 1005mb
Wind field radius: up to 55 miles

And lastly is TD 4, which formed off Florida last night. This one isn't expected to have much time to beef up before coming ashore since it's so close to begin with. However, it is still forecast to pick up some strength. To the tune of 60mph winds since the Gulf if is untouched and very very warm. TD 4's stats:

Location: 28.7N 84.6W
Moving: NW @ 14mph
Winds: 35mph gusting to 45mph
Pressure: 1011mb

TS Ana & TD 3

Well, as of 11am, TD 2 has been upgraded to a tropical storm. It is forecast to intensify until just below hurricane status, as per the GFS guidance. Basically, it looks like the GFS nailed these two storms dead on. The stats on Ana:

Location: 14.3N 48.3W
Moving: W @ 16mph
Winds: 40mph gusting to 50mph
Pressure: 1005mb
Wind field radius: up to 70 miles

Now, these stats are a bit generous imo, as the satellite presentation is very weak at best in the convection department. But we shall see if it can flare up as nice as it did last night & keep that going long enough to stabilize.

Moving on to TD 3. This sucker is looking nice. Very nice as a matter of fact. Deep convection is everywhere, as is one large feeder band. However, the northwest quardent is heavily damaged by strong upper level winds atm. This should go away over the next day or two, giving this system plenty of room to bulk up. And it is expected to do that and then some. Rapid intensification is expected once the shear lessens, possibly reaching major hurricane status by day 5. TD 3's stats:

Location: 11.5N 34.0W
Moving: W @ 17mph
Winds: 35mph gusting to 45mph
Pressure: 1006mb
