Tropical Storm Gustav has formed from one of the waves we've been watching as Fay wandered off and is moving towards the Caribbean; it's early yet; the spaghetti models are pointing in several directions, and the cone of uncertainty is big. It's about a week away from us.

(Thanks for the link, Lloyd)
Update: Gustav is now a category 1 hurricane; it is weakening over Haiti, but it may make it up to a category 3; it should be way west of Florida in the Gulf of Mexico.
Update (8-27-08): It's still over Haiti and the cone of uncertainty is brushing Florida's west coast.
Update (8-28-08): Gustav will probably only become a category 2, and the cone of uncertainty has moved west away from Florida.
Update: Gustav has moved farther away from Florida and is predicted to be a category 3 after all. Intensification should begin tomorrow about midday, and it should hit the north coast of the Gulf Monday night or Tuesday.
