7-16-2000 Severe Storms


Severe thunderstorms developed across northeast South Carolina during the mid afternoon and moved slowly north into southeast North Carolina, producing hail ranging in size from 0.75 to 1.75 in diameter across Columbus county. Other storms developed across southeast North Carolina and also move north producing hail ranging in size of 0.75 to 2.75 inches and damaging winds across Pender county. A third round of severe weather occurred that evening when additional storms moved southeast across Robeson, Bladen and Columbus counties producing hail ranging from 0.75 to 1.75 inches along with some damaging wind gust. A total of 13 severe thunderstorm warnings were issued for 9 counties in NWS Wilmington's county warning area.

The thunderstorms developed during the afternoon along a trough of low pressure that had migrated into the area and along the sea breeze. The development of severe storms was aided by an upper level system with cold air aloft that was directly over the area. The first report of large hail was received around 3:20 PM as 1 inch diameter hail fell near Tabor City in Columbus county. As other storms developed, several other reports of large hail were received with the largest report of 2.75 inches occurring in Penderlea in Pender county around 4:45 PM. The last report of large hail was received at 9:57 PM when 1.75 inch diameter hail fell in Ash in Columbus county.

Occasional wind damage was reported from some of the storms. The most widespread damage occurred in western Pender county around the time of the large hail during the afternoon. Numerous trees were knocked down and crop damage occured because of the high winds.
