CHIEF METEOROLOGIST BILL WALSH says....

We've got our first real tropical weather system that will make note this season developing in the Eastern Atlantic. I expect this to be named DEAN sometime tonight or tomorrow as it moves towards the west.

It's moving rather fast, but typical given it's position at such a low latitude and given the easterly shear it's undergoing.

The convection has been somewhat displaced to the west of the low level circulation as noted in the NHC discussion, but I would expect it to slow a bit in the 48 to 72 hour period which would favor some strengthing.

Two things in the future will drive this storm and they're both troughs that will move off the east coast into the next 9 days. Trough number one might steer the system slightly northwest vs west/northwest. Once it moves away, we'll see the trend more west until another trough moves east. The strength, timing and placement of this second trough will be critical in where this storm will go and whether it will be a threat to the U.S. and our area of South Carolina.

So...we're watching and plotting and will keep you updated. We're not getting the cots out yet, but everyone should note that the real season has begun and it only takes one; so we'll be ready here in the storm center for whatever Mother Nature brings our way. Thanks for watching...see you in a bit on TV.

Bill
