Promptly follow evacuation and other instructions from local officials. Little change in strength is expected over the next several hours.
"Outside the warning area, there will be blustery conditions with increasing amounts of cloud and rain". As of Tuesday morning, a trio of storms is churning across the Atlantic.
Winds of 40 mph extend outward up to 115 miles (185 km) from the center of the tropical cyclone.
With the expected track bringing a weakening Florence along the eastern and eventually northern outskirts of the CSRA, that means the rain/wind will be the most extreme in those areas.
Florence, however, continues to threaten the east coast as a fierce storm that could trigger flooding as far south as Georgia.
Tropical Storm Issac was one of four weather systems rolling across the Atlantic Thursday, including the unsafe category 2 Hurricane Florence, which was packing winds of nearly 100mph as it headed towards the Carolinas on the east coast of the United States. Maximum sustained winds Friday morning were near 35 miles per hour with higher gusts. Florence is a category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale. The depression is moving toward the west near 16 miles per hour (26 km/h), and this general motion with some decrease in forward speed is expected over the next couple of days.
Sea conditions around Barbados are forecast to deteriorate later today and will continue into Thursday with swells expected to peak near 3.5 metres in open water. A NOAA hurricane hunter aircraft will soon fly through the centre of Isaac, and will provide a better assessment of the intensity of the tropical storm and the extent of its winds.
The estimated minimum central pressure is 949 mb (28.03 inches).
States of emergency were declared in the Carolinas; Virginia; Washington, DC; and Maryland, where some coastal areas are still recovering from summer storms. Surge-related flooding depends on the relative timing of the surge and the tidal cycle, and can vary greatly over short distances.
