About lightning in North Carolina
North Carolina runs from the Appalachians to the Atlantic, and its lightning reflects that range — mountain afternoon storms, Piedmont frontal systems, and coastal sea-breeze and tropical activity. The active window runs May through September. Storms here often build fast and strike from their leading edge. The live distance and trend to the nearest flash give you more warning than a statewide average ever could.
