DISCUSSION AND OUTLOOK
----------------------
At 1100 AM EDT (1500 UTC), the center of Tropical Storm Bertha was
located near latitude 33.3 North, longitude 79.5 West. Bertha is
moving toward the north near 15 mph (24 km/h) and this 
general motion is expected to continue through tonight with a 
gradual increase in forward speed. On the forecast track, Bertha 
will move inland across eastern and northern South Carolina later 
today and into central North Carolina by tonight.

Maximum sustained winds are near 50 mph (85 km/h) with higher gusts.
weakening is forecast during the next 48 hours. Bertha is expected 
to weaken to a tropical depression later today and become a remnant 
low tonight.

Tropical-storm-force winds extend outward up to 25 miles (35 km)
from the center.

The estimated minimum central pressure is 1005 mb (29.68 inches).


HAZARDS AFFECTING LAND
----------------------
RAINFALL:  Bertha is expected to produce total rain accumulation of 
2 to 4 inches with isolated totals of 8 inches across eastern and 
central South Carolina into west central to far southeastern North 
Carolina and southwest Virginia.  Given very saturated antecedent 
conditions, this rainfall may produce life threatening flash 
flooding, aggravate and prolong ongoing river flooding, and produce 
rapid out of bank rises on smaller rivers.

WIND:  Tropical storm conditions are expected to continue near the
coast for the next few hours.


NEXT ADVISORY
-------------
Next intermediate advisory at 200 PM EDT.
Next complete advisory at 500 PM EDT.
