Tropical Storm Isaac did not strengthen Wednesday, maintaining 45 mph winds because of wind shear and the storm having more than one center of circulation.

There’s still a lot of uncertainty about what happens with Isaac through the weekend and into Monday. Right now, the latest information that I have suggests a Category 1 hurricane somewhere near Southwest Florida by Monday afternoon.

The National Hurricane Center found the storm actually has multiple centers of circulation. These are expected to consolidate into one center Wednesday night and Thursday. At that point, it will be easier to more precisely forecast the storm’s path into the northern Caribbean.

Winds above the storm are keeping the system from growing vertically and getting stronger. This wind shear is forecast to weaken Wednesday night and Thursday as well. We are expecting about a 60 mph winds from Tropical Storm Isaac by Thursday afternoon.

The storm passed through the Leeward Islands Wednesday afternoon and is headed for the northern Caribbean Sea.

If you have family in Puerto Rico, the storm will pass to the south of the island this afternoon. Tropical storm warnings are in effect.

Haiti is under a hurricane warning, as Isaac is expected to be a Category 1 storm with 80 mph winds near the island on Friday afternoon. How long the storm interacts with Haiti and Cuba will determine what comes toward Florida on Monday.

This is a great time to visit and get tips on what you need to do to prepare yourself, family and property.
