From the Colleton County Emergency Preparedness Agency:

 

At 5 p.m. EDT (2100 UTC), the area of minimum pressure associated

with the disturbance was estimated near latitude 32.2 North,

longitude 79.9 West. 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.

The estimated minimum central pressure is 1006 mb (29.71 inches).

 

HAZARDS AFFECTING LAND

———————-

WIND:  Tropical storm conditions are expected within the warning

area tonight and Tuesday and tropical storm conditions are possible

in the watch area tonight.

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.

Tuesday along the South Carolina and North Carolina coasts.
