The system is moving toward the northeast near 12 mph (19 km/h), and this general motion with a gradual increase in forward speed is expected during the next couple of days. On the forecast track, the system will move over or near the coast of South Carolina tonight and move along the North Carolina Outer Banks on Tuesday. Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. These winds are over water well to the east of the area of minimum pressure. Although the disturbance has not become any better organized today, there is still potential for the system to become a tropical storm during the next 24 hours. After that time, the low should begin to intensify as an extratropical cyclone. * Formation chance through 48 hours...high...70 percent * Formation chance through 5 days...high...70 percent Tropical-storm-force winds extend outward up to 85 miles (140 km) to the east of the area of minimum pressure.

RAINFALL: The low is expected to produce total rain accumulations of 3 to 6 inches along the northeastern South Carolina, North Carolina, and southeast Virginia coasts, with possible isolated maximum amounts of 9 inches. The heavier rains may result in some flooding concerns along coastal areas. SURF: Swells generated by this disturbance will affect portions of the Georgia, South Carolina, and North Carolina coasts during the next day or two, creating dangerous surf and rip current conditions. Please consult products from your local weather office. TORNADOES: A brief tornado is possible tonight through midday Tuesday along the South Carolina and North Carolina coasts.
