ATL GUSTAV: Tropical Depression - Discussion

I'm going to bed. I posted pictures of what Wilma looked like before and after R.I. Go take a look at them and you will see what i mean.. apart from no pinhole eye, gustav's convection pattern is eerily akin to wilma's.

I think this recon pass may well find winds that could justify major hurricane, even the NHC discussion just noted the same thing.

One thing is for sure...If Gustav didn't have the Gulf Coast's full attention last night, he will this morning...Especially when everyone gets up and see's him flexing his muscle...

I'm surprised NHC went that high. SFMR does not yet justify a cat 2, though it should on this pass

Just to add a little bit more on hot towers:

Basically a hot tower is when a very tall, dense cumulonimbus cloud builds from the lowest layer of the troposphere and stretches upwards to the stratosphere. They can reach upwards of 11 miles in height. When such a vast amount of latent heat is produced due to the rising of moist air, which results in a cooling mechanism of the water vapor into liquid water, we can see hot towers form. When a hot tower forms, it generally acts like the pistons found in an engine, releasing energy in to the center of the storm resulting in lowering of surface pressure and consequently increasing wind speed.

Cooling cloud tops is an indication of convection building upwards. It does not always constitute a hot tower forming.

I assume its becuase they think there will be higher winds found in the NE quadrant as well Derek, they must be thinking the SFMR is giving low returns or something?

Pressure continued to drop even after the wind shift. What do you make of that Derek from an RI'ing storm?

EDIT: NM they did a loop. I'm an idiot.

Another special advisory/update coming soon? I think it's officially in RI now.

Hurricanewatcher2007 · #6477 Postby **Hurricanewatcher2007** » Sat Aug 30, 2008 4:38 am

the last VDM was at 7:41 and had a pressure of 965mb

It already has been noted by NHC. First line of Disco:
GUSTAV HAS BEEN RAPIDLY INTENSIFYING DURING THE OVERNIGHT HOURS.
