According to the National Weather Service (NWS), “strong to severe thunderstorms will be possible later this afternoon into the evening, especially across areas along and south of the I-66 corridor and points westward. Main threats will be large hail, damaging winds and an isolated tornado possible.”
A Flood Watch is in effect for much of the area through Wednesday afternoon. Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. Multiple rounds of showers and thunderstorms are expected through Wednesday. One to two inches of rain is most likely, with localized amounts up to 4 inches possible. This may result in flooding of small streams and creeks. Flash flooding is possible.
Per the NWS, “You should monitor later forecasts and be alert for possible Flood Warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop.” The Flood Watch runs until 6pm on Wednesday.
