With Hurricane Florence, numerous coastline will see water levels from the storm surge rise over 3 feet, with some families seeing over 9 feet of water near their homes.

Florence, now a tropical storm, swirled at a near-standstill over the Carolinas on Saturday, dumping non-stop rain over areas already flooded by seawater and swelling rivers and creeks across both states.

The tropical storm-force winds from Helene should begin impacting the Azores around 8 a.m. Monday.

Isaac is moving toward the west near 15 miles per hour, and this general motion with a decrease in forward speed is expected for the next few days.

At 11 a.m., the center of the system was about 190 miles east-southeast of Kingston, Jamaica. The system has now weakened into a Tropical Depression and convection associated with Isaac diminished considerably. Isaac also has the potential to bring 1-2 inches of rain to portions of St. Croix.

Florence, a potentially life-threatening Category 4 hurricane, is on track to make landfall in North Carolina or SC on Thursday (Sept. 13).

By the time it moves through the central Lesser Antilles, Isaac is expected to be near hurricane strength before weakening on Friday. Parts of North Carolina had seen storm surges - the bulge of seawater pushed ashore by the hurricane - as high as 10 feet (3 meters), he said. "This rainfall may cause life-threatening flash floods". Tropical storm-force winds extend outward from the eye of the storm up to 140 miles.

Preparing for the worst, about 9,700 National Guard troops and civilians were deployed with high-water vehicles, helicopters and boats.

A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, in this case within 36 to 48 hours.

The U.S. National Hurricane Center (NHC) provided the latest update on Hurricane Florence at 8 a.m. on September 12.
