Tropical Storm Conditions for Eastern North Carolina Tuesday through Thursday
Hurricane Maria continues to move northward, and the center will stay well off the East Coast. Maria is a large storm and is generating tropical force winds over a wide area. Tropical storm force winds of 35-45 mph, with gusts exceeding 55 mph, are expected in the region starting today and ending Thursday morning. In addition to windy conditions, heavy rainfall is expected. Rainfall amounts of 1-2 inches with locally higher amounts in excess of 3 inches are forecast. Maria is also likely to produce storm surge in excess of 2-4 feet in some areas.

Thunderstorms and Excessive Rainfall Tuesday from Southwest Texas to Western Oklahoma
A stalled front stretching from southwest Texas into southern New Mexico will continue to promote the development of thunderstorms. Deep moisture spreading into the region combined with favorable wind shear will allow for a few strong to severe thunderstorms. Gusty winds and hail will be the primary hazards with these storms. In addition, heavy rain is also expected. Rainfall amounts of 3-5 inches with isolated higher amounts in excess of 6 inches are forecast.

Continued Excessive Rainfall for West Texas Wednesday and Thursday
The slow moving cold front moving across the central US is expected to stall over Southwest Texas. This boundary will continue to interact with moisture being brought northward from the Gulf of Mexico. This will bring even more rainfall to already saturated ground on Wednesday. Showers and thunderstorms associated with this front are expected to be widespread and persist into Thursday. Two day rainfall totals of 3-6 inches with locally higher amounts are forecast. Localized flash flooding will also be a concern.
