The storm remained a Category 2 hurricane with maximum sustained winds of 100 miles per hour. As the system progresses westward into the eastern Caribbean Sea, more organised convection trailing Isaac is expected to affect Barbados, bringing moderate to heavy showers and occasional gusty winds from early Thursday morning and into Friday.
The hurricane will weaken as it moves over cooler water, and is expected to be downgraded from hurricane to tropical storm status before making the transition to post-tropical storm on Sunday.

Tropical Storm Issac was one of four weather systems rolling across the Atlantic Thursday, including the unsafe category 2 Hurricane Florence, which was packing winds of nearly 100mph as it headed towards the Carolinas on the east coast of the United States. "On the forecast track, the center of Florence will approach the coasts of North and SC later tonight, then move near or over the coast of southern North Carolina and northeastern SC in the hurricane warning area on Friday", the briefing said.
