A flash flood watch is still in effect through Wednesday evening for western North Carolina.

Thunderstorms are likely to produce heavy rainfalls through Wednesday. A deep low pressure system spinning over the Midwest will continue to produce moist and unstable conditions over the southeastern United States.

This should result in brief periods of showers and thunderstorms through Wednesday, especially tonight.

These thunderstorms may produce several rounds of heavy to excessive rainfall with flash flooding of small streams and creeks possible, and main stem river flooding becoming more likely.

Drying from the West will likely not occur until Wednesday evening at the earliest.

Storm total rainfall of two to four inches is expected across the western Carolinas and northeast Georgia, with locally heavier amounts possible in areas repeatedly affected by thunderstorms.

Rainfall of more than five inches in similar storms has been associated with an increased risk of landslides and rock slides. If you live on a mountainside or in a cove at the base of a mountain, especially near a stream, be ready to leave in advance of the storm as quickly as possible should rising water, moving earth, or rocks threaten.

Consider postponing travel along mountain roads during the period of heavy rainfall. A flash flood watch means that conditions may develop that lead to flash flooding. Flash flooding is a very dangerous situation. You should monitor the latest forecasts and be prepared to take action should flash flood warnings be issued.
