"Some strengthening is possible during the next 12 to 24 hours, but gradual weakening should begin thereafter", the hurricane center said. It is expected to continue moving to the west toward the Caribbean by the end of the work week. 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.

Olivia's maximum sustained winds are about 65 miles per hour, after the storm weakened from Category 1 strength, forecasters said. A tropical storm warning means tropical storm conditions are expected somewhere in the area within 36 hours, and a watch within 48 hours. If Isaac survives, some forecast models want to turn it to the northwest towards the Gulf next week, so we'll keep watching this one closely.

It's a detail that almost got lost among all the wind, rain and storm surge data sent out by the National Hurricane Center on Wednesday.

- Isaac is now a strong tropical storm over the Central Tropical Atlantic. As of Tuesday, several islands in the area including Dominica, Martinique and Saint Lucia were all under a hurricane watch, the islands to the north like Antigua and St.John's were under a tropical storm watch.

"Isaac is expected to produce additional rainfall of 2 to 3 inches with isolated maximum totals of up to 5 inches across southeast Puerto Rico", the center said.

A NOAA Hurricane Hunter plane that investigated the oncoming Tropical Storm Isaac Wednesday evening and found that the system has weakened a bit, according to the National Weather Service.

The Meteorological Service has issued a Severe Weather Alert for all parishes effective Sunday until Monday.

Residents especially those in flood and landslide prone areas are to be vigilant; and small craft operators and sea bathers are advised to exercise caution due to locally rough seas. These swells are likely to cause life-threatening surf and rip current conditions.
