Thursday Afternoon Update: 3:44 PM “Latest on Gustav”

As if Gustav wasn’t enough, Tropical Storm Hanna now poses a threat to the southeastern U.S. Hanna formed earlier today, northeast of the U.S. Virgin Islands. Hanna is forecasted to track northwest and then turn more westward by Monday. At that time Hanna could be a hurricane. The possibilities are wide open beyond Monday as Hanna could impact portions of Florida, Georgia, or the Carolinas.

The system that poses more of a threat to our area, at-least in the near future, is Gustav. This system is near hurricane strength yet again. Gustav is impacting Jamaica and the land interaction should prevent rapid organization tonight. Today’s official forecast cone from the National Hurricane Center has shifted slightly westward and this places communities like Morgan City, Louisiana in the center of the cone. We’re fairly confident Gustav will be making it into the southern Gulf of Mexico, but from that point the forecast varies greatly. Be aware that a landfall could potentially occur anywhere within the cone and not only the center of the cone. One model in particular the GHM, which is advanced form of the GFDL, has a landfall taking place near Mobile. Our forecast now highlights the possibility of heavy rain and wind by Tuesday. As for more direct wind related impacts, there is still a lot to be determined.

If you have a Labor Day weekend trip planned for locations near or along the Gulf Coast, specifically locations between New Orleans and Destin, be aware that weather conditions could go downhill quickly starting on Sunday. Louisiana has already declared a state of emergency and preparations are already being made for possible evacuations. As for the Alabama Gulf Coast and the Florida Panhandle, state officials are making early preparations in case evacuations are warranted. If we hear of possible evacuations over the coming days we will certainly bring you that information. I know many Alabama fans will be making the trek to Atlanta for the Clemson game and the weather looks fine for your travels east.

Our weekend forecast looks fine, with partly cloudy skies and only isolated afternoon thunderstorms. By Monday and Tuesday clouds will thicken, with rain becoming likely. Once again the future track of Gustav will tell the story. Be prepared for the possibility of power outages and windy conditions by Tuesday or Wednesday. We will have much more on our news at 4,5,6, & 10.

“Hanna Forms, Gustav Gaining Strength” 11:13 a.m.

Tropical Storm Hanna formed today and this system is expected to develop into a hurricane. A westward shift in track is expected to take place, which would mean another threat to the southeastern U.S. By the way, pressure continues to fall in Gustav’s center and the system is expected to strike Jamaica today. Stay tuned!
