DISCUSSION AND OUTLOOK
----------------------
At 500 PM EDT (2100 UTC), the center of Tropical Depression Bertha
was located near latitude 34.4 North, longitude 80.3 West. The
depression is moving toward the north-northwest near 15 mph
(24 km/h). A turn toward the north at a faster forward speed is
expected tonight, followed by a turn toward the north-northeast on
Thursday. On the forecast track, Bertha will move across northern
South Carolina this evening and into central North Carolina and
southwestern Virginia later tonight.
Maximum sustained winds have decreased to near 30 mph (45 km/h)
with higher gusts, mainly along the coast to the east of the
center. Additional weakening is expected, and Bertha is forecast
to degenerate to a remnant low pressure area on Thursday.
The estimated minimum central pressure is 1008 mb (29.77 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 northeastern
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: Gusty winds will continue over portions of eastern South
Carolina this evening.
