When Isaac reaches the west-central Caribbean Sea in a couple of days, the shear may relax somewhat and the global models suggest that there will be an increase in mid-level moisture.

As a result, two foreign governments and one local government have taken the decision to end their islands' storm warnings or storm watches.

All watches and warnings were discontinued yesterday.

"Isaac has become less organized and is now a weak Tropical Storm".

The hurricane is now moving north at around 20km/h, and was expected to slow down today, becoming a tropical storm.

The Portuguese weather service said that wind gusts of up to 74 mph are possible by the weekend in the Azores, an island chain about 850 miles west of Portugal. The storm is expected to slow down and possibly stall near or over the coast on Friday.

"Regardless of development, heavy rainfall and gusty winds are expected across portions of northeastern Mexico, Texas, and Louisiana on Friday and Saturday", the hurricane center said. Since we're now at the height of hurricane season it's important to stay focused and have plans ready, should any tropical activity threaten.

Tropical Storm Joyce formed late on Thursday and is never expected to affect land.

But according to the NHC, "Isaac is forecast to gradually weaken over the next few days, and could degenerate into a tropical wave at any time".

Steered westward by high pressure to its north, Isaac is forecast to move through the Lesser Antilles today and tomorrow.

Less rain is predicted for St. Thomas, St. John and Water Island.

Florence is the most worrisome of the bunch as it lumbers toward the East Coast carrying the threat of a deadly 13-foot ocean surge and flooding rains.

On the heels of Hurricane Lane in the Pacific, Tropical Storm Olivia, now with winds as high as 65 miles per hour, is expected to move through the main Hawaiian islands of Hawaii, Maui and Oahu Tuesday evening, according to the Central Pacific Hurricane Center.
