DISCUSSION AND OUTLOOK ---------------------- At 1100 PM EDT (0300 UTC), the center of Tropical Depression Bertha was located near latitude 36.0 North, longitude 80.5 West. The depression is moving toward the north near 23 mph (37 km/h) and this motion is expected to accelerate and turn north-northeast on Thursday. Maximum sustained winds are near 30 mph (45 km/h) with higher gusts. Weakening is forecast during the next 24 hours. Bertha is expected to dissipate Thursday night. The estimated minimum central pressure is 1009 mb (29.80 inches). HAZARDS AFFECTING LAND ---------------------- RAINFALL: Bertha is expected to produce total rainfall accumulations of 2 to 4 inches with isolated totals of 8 inches across northeastern South Carolina into sections of 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 are possible across the higher elevations of southwest Virginia and West Virginia as Bertha progresses across the Appalachians.
