The National Weather Service has issued a Flash Flood Watch, in effect from 9 a.m. through this evening.
A Flash Flood Watch means that conditions may develop that lead to flash flooding. Flash flooding is a very dangerous situation.
Multiple rounds of showers and thunderstorms are expected today with localized heavy rainfall rates of 1 to 2 inches per hour possible.
Runoff from excessive rainfall may cause rapid rises of water in low-lying and poor drainage areas as well as streams and creeks, resulting in flash flooding. Urban areas will be most susceptible.
You should monitor later forecasts and be prepared to take action should flash flood warnings be issued.

The National Weather Service has issued a Flash Flood Warning for the cities of Fairfax, Alexandria and Falls Church, as well as central Fairfax County until 2:30 p.m. today.
A Flash Flood Warning means that flooding is imminent or occurring. If you are in the warned area move to higher ground immediately. Residents living along streams and creeks should take immediate precautions to protect life and property.
The weather service reports that at 10:24 a.m., Doppler radar indicated thunderstorms producing heavy rain across the area. Over two inches of rain have already fallen near Merrifield, with over one inch in much of the remainder of the area. Additional rainfall amounts of one to two inches are possible. Flash flooding is expected to begin shortly.
Precautions / Preparedness Actions
- Keep children away from creeks and their potentially rapidly rising waters.
- Turn around, don’t drown when encountering flooded roads. Most flood deaths occur in vehicles. Never drive your vehicle into areas where the water covers the roadway. Flood waters are usually deeper than they appear. Just one foot of flowing water is powerful enough to sweep vehicles off the road.
You may also receive a WEA alert on your phone. Wireless Emergency Alerts (WEA) are free informational text messages sent to WEA-enabled phones within range of an imminent and dangerous local situation, severe weather event or AMBER alert. The National Weather Service and Fairfax County are among the select entities that can send these messages to your phone regardless if you signed up.

The morning commute is always interesting here in Northern Virginia — but add rain and things can get complicated.
The Virginia Department of Transportation (VDOT) has some good guidance for safe driving in the rain, like keeping extra distance between your vehicle and the vehicle in front of you. Also, turn on your lights anytime it’s raining. Check out the video for more tips.
And most importantly, remember to turn around, don’t drown if you encounter high water or standing water on area roadways.
It is impossible to tell the exact depth of water covering a roadway or the condition of the road below the water.
It is never safe to drive or walk through flood waters. Any time you come to a flooded road, walkway, or path, follow this simple rule: Turn Around Don’t Drown.
