A Hurricane Warning has been issued for portions of the northern Gulf coast from east of Morgan City, Louisiana to Destin, Florida.
This includes New Orleans, Lake Pontchartrain and Lake Maurepas. Preparations to protect life and property should be rushed to completion in the warning area. Additional Tropical Storm Warnings are now in effect for portions of the Gulf coast.
Isaac is entering the southeast Gulf of Mexico this evening, centered about 40 miles southwest of Key West. Maximum sustained wind are 60 mph. Some strengthening is forecast during the next 48 hours, and Isaac is expected to become a hurricane.
The forecast track has the center of the storm moving away from the Florida Keys tonight and over the eastern Gulf of Mexico on Monday, then approach the northern Gulf coast on Tuesday.
It is important not to focus on the exact track of Isaac due to the uncertainties in the forecast, and the fact that this storm has a large area of tropical storm-force winds, extending outward up to 205 miles from the center.
