The National Weather Service issued Flash Flood Watch for Fairfax County and surrounding areas just days after major flooding hit.
The watch is in effect from 2 p.m. through late tonight (July 11).
More from NWS:
* Showers and thunderstorms are expected this afternoon and evening. Torrential rainfall may lead to totals exceeding 2 inches in a short period of time. This may cause flash flooding of small streams and other poor drainage urban areas.
PRECAUTIONARY/PREPAREDNESS ACTIONS…
A Flash Flood Watch means that conditions may develop that lead to flash flooding. Flash flooding is a very dangerous situation.
You should monitor later forecasts and be prepared to take action should Flash Flood Warnings be issued.
After more than 55 water rescues on Monday, forecasters are also reminding people to “turn around, don’t drown” when encountering water of unknown depth on the roads.

Updated at 2:00 p.m. — The power outages above Wolf Trap and east of Langley Fork Park are now resolved. A new power outage popped up by Great Falls Street and Swinks Mill Road affecting 26 people. Power is expected to be restored between 4-9 p.m. today, according to Dominion.
Earlier: After a morning of violent rain and flooding, around 150 people are left without electricity in the McLean area.
Over by Langley Fork Park, 31 customers are without power because of the storm. Dominion Energy expects power to be restored between 1-6 p.m. today (July 8).
West of Pimmit Park, there are still around 48 people without power. The Dominion Energy map said the outage was caused by a “broken pole.” Crews arrived around 11 a.m. to begin work and people can expect their power to be back between 3-8 p.m.
North of Wolf Trap and just south of Old Dominion Drive, 78 customers don’t have power. The cause is to be determined by the investigation. Dominion expects power to be restored there between 2-7 p.m.
Several other outages affecting nine or fewer people are scattered throughout McLean and Falls Church.
Earlier today, media relations for Dominion Energy said that around 12:30 p.m. the site of a larger power outage was inaccessible to crews because of road washout. That outage was cleared up before 1 p.m.
Anyone without power can report new outages to Dominion Energy at 866-366-4357 or on their website.
