Isaac is on the move and expected to grow stronger over the next 24-hours.


The latest on Isaac from ABC 7 Weather and Baron Services Curtis Brideau.

"Tropical Storm Isaac is currently located about 50 miles SSE of Key West, Florida and moving WNW at 18 mph. Isaac presently has maximum sustained winds of 60 mph, with a central pressure of 994 MB. Satellite imagery and radar show a more organized storm with a partial eye wall becoming apparent on radar. While Isaac has become more structured, its intensity has not changed much today. Gradual strengthening is expected as it enters the Gulf of Mexico.

Isaac should continue on a west-northwestward to northwestward motion during the next 48 hours.

The BAMS model has Isaac passing over the Florida Keys this afternoon and in to the Gulf of Mexico later tonight. The National Hurricane Center is forecasting Tropical Storm Isaac to strengthen to a Category 1 hurricane by tonight then to a Category 2 hurricane by Wednesday morning. The ECMWF and NAM have Isaac turning to the North before landfall and moving on-shore between Mobile, AL and Pensacola, FL. However, most of the models including the BAMS now have Isaac continuing its west-northwestward track all the way until landfall and are clustered between New Orleans, LA and Houma, LA.

The current NHC forecast track has Isaac making landfall Wednesday morning around Gulfport, Mississippi while the latest BAMS model run goes to the west has Isaac making landfall around 10 am EDT Tuesday near Venice, Louisiana."
