McLean Road Reopens After Tree Cleared, Flash Flood Watch Issued

UPDATE: Old Dominion Drive has reopened.

MCLEAN, VA — Fairfax County Police reported a road closure on one of McLean's main roads on Wednesday. Residents should be aware of potential impacts from thunderstorms starting in the afternoon.

According to police, Old Dominion Drive is closed between Briar Ridge Road and Franklin Park Road due to a fallen tree blocking the road. The road closure is just east of the Chesterbrook shopping center near the Arlington County border. Drivers should expect extended delays.

The National Weather Service also alerted area residents to potential flash flooding Tuesday afternoon and evening. A flash flood watch has been issued for the greater region from noon to the evening.

The NWS outlook for excessive rainfall is moderate for McLean and the greater region. Heavy rain and slow movement of storms could lead to flash flooding, according to the NWS forecasters. The most likely time for flash flooding is between 2 p.m. and 8 p.m. Areas prone to flooding should prepare.

Overnight rain has already led to severe impacts for one Northern Virginia community. According to the Washington Post, a sinkhole formed in Manassas Park as a result of flash flooding early Wednesday. There were no reported injuries, but the sinkhole blocked some condo and townhouse residents from using the road to exit.
