Posted at 12:45 p.m.
The National Weather Service has issued a severe thunderstorm watch in effect until 8 p.m. this evening, Thursday, May 15.
In addition, a flash flood watch is in effect from 6 p.m. tonight through Friday afternoon for Fairfax County and the National Capital Region. A flash flood watch means that conditions may develop that lead to flash flooding.
Showers and scattered thunderstorms are expected with periods of heavy rain developing late this afternoon and continuing through midday Friday. The heaviest rain will be late tonight into Friday morning. Rainfall amounts of 2 to 4 inches are expected with locally higher amounts possible. This amount of rainfall has the potential to produce flash flooding, especially in urban areas and along small rivers and streams.
Huntington and Belle View/New Alexandria Residents
Based on the latest NWS forecast, county officials estimate that if we receive localized rainfall of 1-1/2 inches of rain within a one hour period, residents will likely experience minor street flooding in the Huntington area. As a precaution, residents in the Huntington area are encouraged to move vehicles to higher elevations.
County officials also believe that residents experience localized street flooding near the intersection of Olde Towne Road an Wood Haven Road and the vicinity of 6700 West Wakefield Drive in the Belle View/New Alexandria areas. However, no structural flooding in the Huntington or Belle View/New Alexandria areas is anticipated based on the latest forecast. Staff from the county’s Public Works and Environmental Services, public safety and emergency management offices will continue to monitor the storm and provide updates if the forecast or anticipated conditions worsen.
