As of 2 p.m., the slow-moving storm barely had Category 1 hurricane strength and was nearly at a standstill over southeastern North Carolina, according to the Associated Press.

That storm was moving through the eastern Caribbean Sea, bringing bands of rain over the Lesser Antilles, according to the National Hurricane Center (NHC).

Isaac is moving west at 21 miles per hour.

A tropical storm warning continues for Martinique, Dominica and Guadeloupe. The main tropical focus has been Florence which made landfall in North Carolina as a significant hurricane, late last week.

Maximum sustained winds have decreased to near 40 miles per hour (65 km/h) with higher gusts. Strong wind shear is also affecting Joyce, and it could dissipate as early as Monday.

"While it remains possible the system becomes a tropical storm, we see no reason right now to believe it becomes more than that, and we're not convinced it develops at all", said Space City Weather's Eric Berger in the blog.

The National Hurricane Center (N.H.C.) in its 5:00 p.m. advisory said all tropical storm watches and warnings for Isaac have been discontinued, news that will be welcomed by interests in the Caribbean.

In the Pacific, Tropical Depression Olivia continues to move west away from Hawaii. As it pushed past and south of Cuba it is forecasted to weaken further, into a Tropical Depression.

The estimated minimum central pressure is 949 mb (28.03 inches). Coastal Flooding: Outside the Storm Surge Watch area, minor coastal flooding could occur around the time of each high tide Thursday and Friday.

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.

SURF: Swells generated by Florence are affecting Bermuda, portions of the U.S. East Coast, and the northwestern and central Bahamas These swells are likely to cause life-threatening surf and rip current conditions.
