Tropical storm conditions will spread northward within the Tropical Storm Warning area from Florida to North Carolina through Monday night. Tropical storm conditions are possible in the Tropical Storm Watch area beginning on Tuesday.
The combination of a dangerous storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline. The water could reach the following heights above ground somewhere in the indicated areas if the peak surge occurs at the time of high tide…
– Edisto Beach SC to Cape Fear NC…2-4 ft
– Sebastian Inlet FL to Edisto Beach SC…1-3 ft

At 8 p.m. EDT, the center of Tropical Storm Isaias was located about 55 miles (90 km) east-southeast of Cape Canaveral Fla. It’s moving toward the north-northwest near 9 mph (15 km/h), and this general motion is expected to continue through tonight. A turn toward the north and north-northeast along with an increase in forward speed is anticipated on Monday and Tuesday. On the forecast track, the center of Isaias will pass just to the east of the Florida east coast through tonight. The center of Isaias will then move offshore of the coast of Georgia and southern South Carolina on Monday, move inland over eastern South Carolina or southern North Carolina Monday night and move along the coast of the mid-Atlantic states on Tuesday.
Maximum sustained winds are near 70 mph (110 km/h) with higher gusts. Tropical-storm-force winds extend outward up to 115 miles (185 km) from the center. Some fluctuations in strength will be possible during the next 36 hours, but Isaias is expected to be a strong tropical storm when it reaches the coast of eastern South Carolina or southern North Carolina Monday night. Slow weakening is forecast after Isaias makes landfall in the Carolinas and moves across the U.S. mid-Atlantic region late Monday and Tuesday. NOAA buoy 41009, located just off the coast of Cape Canaveral, recently reported a sustained wind of 45 mph (72 km/h) and a gust of 54 mph (87 km/h). A Florida Institute of Technology observing station at Sebastien Inlet measured a sustained wind of 39 mph (63 km/h) and a gust of 48 mph (78 km/h) during the past couple of hours.
Heavy rainfall from Isaias will continue to result in potentially life-threatening flash flooding in the Northwestern Bahamas through tonight. Flash and urban flooding, some of which may be significant in the eastern Carolinas and the Mid-Atlantic, is expected through midweek along and near the path of Isaias across the East Coast of the United States. Widespread minor to isolated moderate river flooding is possible across portions of the Carolinas and the Mid-Atlantic.
