The centre of Isaac passed between Martinique and Dominica with maximum sustained winds of about 45 miles per hour.

Tropical storm warnings were in effect for Martinique, Dominica and Guadeloupe, while watches were in effect for Montserrat, St. Kitts and Nevis, Antigua, and Saba and St. Eustatius.

As of 11 a.m., Florence was located at 33.4 N, 75.5 W, about 145 miles (230 km) ESE of Wilmington, North Carolina, and about 195 miles (315 km) east of Myrtle Beach, South Carolina. Storm winds could intensify through the day and tonight, but weaken slightly Thursday as it nears the coast.
