Tropical Storm Hermine Threat Labor Day Weekend
Hurricane Watches Florida Coastal Bend
Threat to East Coast Increases
Based on the satellite loops the tropical depression has developed a well defined circulation and has been upgraded to a tropical storm. Tropical Storm Warnings are posted for a portion of the Florida Coastal bend and a hurricane watch remains in effect for much of that area as well.

A watch is typically issued 48 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous. A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area within 36 hours. A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 hours. Interests along the United States east coast from Georgia through the Carolinas should monitor the progress of this system. For storm information specific to your area, including possible inland watches and warnings, please monitor products issued by your local National Weather Service forecast office. DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 100 PM CDT (1800 UTC), the center of Tropical Storm Hermine was located near latitude 24.7 North, longitude 88.0 West. Hermine appears to be drifting northward near 2 mph (4 km/h). A north-northeastward motion is expected later today, and a turn toward the northeast with increasing forward speed is expected on Thursday. On the forecast track, the center of Hermine will approach the northwest Florida coast in the warning area on Thursday afternoon. Maximum sustained winds have increased to near 40 mph (65 km/h) with higher gusts. Additional strengthening is forecast during the next day or two, and Hermine could be near hurricane strength by the time landfall occurs. Tropical-storm-force winds extend outward up to 105 miles (165 km) mainly to the southeast of the center. The estimated minimum central pressure is 1000 mb (29.53 inches).
The question now for the east coast is becoming a little more clear as weather models seem to be converging on a more westerly track up the coast just inland. This means that the system could maintain a degree of tropical storm strength as it moves north northeastward. The shift west is because the tropical system has taken longer to move northward and thereby missing the trough that will be moving over the northeast. That trough would have pushed this out to the south. Instead the trough passes by and the bottom part of it cuts off from the main jet stream and lifts the tropical storm northward to our latitude. This is based on the latest GFS model and Nam model. Also other global models are on board.

If this is correct weather conditions will being to deteriorate Saturday afternoon and evening with rain moving in for Saturday night and Sunday. We will have more on this later today. Let me say this and make it clear. THIS IS NOT ANOTHER SANDY. It would appear that the main threat for this would be heavy rain and it might be a drought breaking rain for some areas which will be a good thing. Details will be fine tuned.
