Showers and thunderstorms will move across the area later tonight into early Monday morning. The main threat will be damaging winds and heavy rainfall which could lead to areas of urban and poor drainage flooding.

The National Weather Service says an isolated tornado cannot be ruled out.

The National Weather Service in Mount Holly has issued a flash flood watch for the area through late tonight.

Two rounds of heavy rain are possible. The first one is expected  this evening. A second round of heavy rain is possible after

  midnight. This comes just a few days after the area received 1 to 2 inches of widespread rain, making the ground already very saturated. Any additional rain will quickly become runoff.
