DISCUSSION AND OUTLOOK
At 100 PM CDT (1800 UTC), the center of Tropical Depression Bertha was located near latitude 33.7 North, longitude 80.2 West. Bertha is moving toward the north-northwest near 15 mph (24 km/h). This general motion is expected to continue through tonight, followed by a turn to the north along with an increase in forward speed on Thursday. On the forecast track, Bertha will move across northern South Carolina later today and into central North Carolina by tonight.

Maximum sustained winds have decreased to near 35 mph (55 km/h) with higher gusts, mainly along the coast to the east of the center. Additional weakening is forecast during the next 48 hours, and Bertha is expected to become a remnant low tonight.

At Oyster Landing, SC a wind gust to 41 mph (66 km/h) was reported at 1245 PM EDT. The estimated minimum central pressure is 1007 mb (29.74 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: Gusty winds will continue over eastern South Carolina for the remainder of today.
