Serious doubts about intensity forecast...

#1 Postby Windfall » Sat Sep 04, 2004 7:53 am

I really do not see how the National Weather Center expects this storm to remain a borderline category 2/3 hurricane. Isn't the sheer decreasing and also the SW quadrant growing a bit more organized as a thunderstorm complex fills in? Even more, this storm is moving so slowly that it is projected to make landfall maybe tomorrow morning. Think about it! Less westerly shear, 12+ hours over the gulf stream, and nearly stationary movement. This translates to a category 4 hurricane. Charley was supposed to be a category 2 when it hit land. Then it got upgraded to category 3 by later forecast predictions. When it actually hit land it became a STRONG category 4 even though it was moving almost 20 mph north.

Windfall's assesment seems a *little* doomsdayish to me, but I do see it getting stronger and more organized every frame. With some much time left and only hotter waters ahead, lets just hope she only LOOKS stronger.

While some intensification is possible, Frances will have trouble wrapping up to a CAT 4. A CAT 3 is very possible. Gusts will run up to CAT 4 I'm sure. Everyone in the path better hunker down because the prep time is just about over. Good Luck all!

I totally agree with you. On the last radar imagery, I saw, there is a lot of convection going on. Be interesting to see what the 11 am report has to say.

Well, the thing is, the storm is very large and it will be hard for it to rapidly strengthen. I think Moderate Cat 3(120 mph) is the strongest this can get. Smaller systems(like Charley and Andrew) are more prone to wild changes in strength.
