Streets in the Huntington area have begun to flood, and Fairfax County is encouraging residents there to move their vehicles to higher ground.

Structural flooding is not expected, however, according to a county message sent to Huntington residents.

“In addition to the rain that has fallen throughout the day, the National Weather Service is forecasting an additional 1 to 2 inches of rain in the next hour,” the county said in an email to residents sent at 7:30 p.m. “Based on this forecast, residents can anticipate significant street flooding in the Huntington area.”

Pictures posted by residents on social media this evening show water pooling in the late afternoon on Fenwick Drive and Arlington Terrace. By 8:30 p.m., images provided to Covering The Corridor showed Arlington Terrace overflowing from the continued rains.

Reagan National Airport reported close to three inches of rain today, and more heavy rain is expected tonight. A flash flood watch and a flood warning are in effect until 2 a.m. for all of Fairfax County and some of the surrounding jurisdictions.

Relief from the weather may be hard to find, with forecasters predicting rain every single day this week, with thunderstorms possible on many days. The National Weather Service is reporting that Cameron Run is already past seven feet at Huntington, putting it into the minor flooding stage (see graph below).

The Huntington Levee remains under construction and was reportedly 75 percent complete in the spring. Once completed, the levee and pumping station are expected to protect the Huntington area — which has seen three major floods since 2003 — for everything up to 100-year flooding events.

Note: The Fairfax County Police are updating a list of flooded roads in the county, but none have been listed so far in the Mount Vernon police district. Richmond Highway and Armistead Road in the Lorton area, however, is the site of some flooding (see map).
