local National Weather Service forecast office.


DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 800 AM EDT (1200 UTC), the poorly defined circulation associated
with the disturbance was estimated near latitude 31.0 North,
longitude 80.7 West.  The system has been moving little, and a
slow and erratic motion is forecast through this afternoon, followed
by a faster northeastward motion tonight and Tuesday.  On the
forecast track, the system will move near the Georgia and South
Carolina coasts later today and move along the North Carolina
coast on Tuesday.

Maximum sustained winds remain near 35 mph (55 km/h) with higher
gusts. Some strengthening is possible during the next 48 hours, and
the system is expected to become a tropical storm by Tuesday morning
and then become post-tropical by Tuesday night.

Although satellite and radar data indicate that the associated
showers and thunderstorms show some signs of organization, the
center of circulation is not yet well defined.  Only a slight
increase in the definition of the circulation would lead to the
formation of a tropical cyclone.
* Formation chance through 48 hours...high...90 percent
* Formation chance through 5 days...high...90 percent

The estimated minimum central pressure is 1007 mb (29.74 inches).


HAZARDS AFFECTING LAND
----------------------
WIND:  Tropical storm conditions are possible within the watch
area tonight and Tuesday.

RAINFALL:  The system is expected to produce total rain
accumulations of 3 to 6 inches along the upper 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.
