he National Weather Service has issued a flood watch from noon today, Wednesday, Feb. 3, through late tonight, which means that there is a potential for flooding based on current forecasts.
The combination of melting snow and periods of heavy rain could result in flooding of urban areas and streams this afternoon and tonight. Rainfall amounts will average between one half and one inch, with isolated spots between one and two inches possible. In addition, ice may be on some of the small streams which could enhance the flooding potential.
Please continue to monitor the weather forecast and be alert for possible flood warnings. Those living in areas prone to flooding should also be prepared to take action should flooding develop.
Turn Around. Don’t Drown
Six inches of fast-moving flood water can knock over an adult. As little as 12 inches of flowing water can carry away most vehicles, including SUVs.
Safety first – if you are unsure about the amount of water on a flooded road, Turn Around. Don’t Drown. With heavy rain in the forecast for today, here are a few reminders from our Police Department to keep you safe during a flood:
- Always plan ahead and know the risks before flooding happens.
- If flooding is expected, or is occurring, get to higher ground fast! Leave typical flood areas such as ditches, ravines, dips or low spots and canyons.
- Never drive through flooded roadways. Road beds may be washed out under flood waters. Turn Around Don’t Drown.
Clear Storm Drains
Blocked stormdrains prevent the flow of rain and melting snow from reaching streams and stormwater detention ponds. The water then backs up into streets and yards and may flood basements. Blocked stormdrains also may damage residential and commercial property and cause traffic delays.
Keep the openings of storm drains clear of snow and debris to help alleviate potential flooding and to protect the environment. At no time, however, should a resident attempt to enter a storm drain to remove debris.
Property owners are responsible for driveway culverts and bridges that are part of the driveway structure and are not public storm drainage system structures. Storm drains outside rights-of-way and easements are privately maintained by the property owner.
To report a blocked storm drain, call Fairfax County Stormwater Management, 703-877-2800, TTY 711, or the Virginia Department of Transportation at 703-383-8368, TTY 711.

You can lose power at any time for a variety of reasons.
Add in heavy rains + saturated ground + high wind gusts + potentially wobbly trees, and that’s a recipe for possible power outages.
- Keep your digital devices charged!
- Back up critical files on your computer.
- Unplug electrical equipment. Spikes and surges could occur as power is restored, damaging equipment.
- Make sure that your emergency supply kit can be found easily if the lights go out.
- If you use well water, pre-plan by filling a bathtub with water for use with sanitation, etc.
If Your Power Goes Out
- Report your outage! Never assume a neighbor has reported it.
- Use a flashlight or battery-powered lantern for emergency lighting. Never use candles.
- Unplug electrical equipment until a steady power supply returns.
- If you have a police, fire or medical emergency, call or text 9-1-1. For non-emergency needs, call 703-691-2131.
Food safety is a big concern if you lose power for a long time. Keep refrigerator and freezer doors closed as much as possible. First use perishable food from the refrigerator. An unopened refrigerator will keep foods cold for about 4 hours. More tips:

Downed trees may become an issue in the next few days with the combination of soaking rainfall and gusty winds in the forecast. We want you to be safe and know what to do if a tree falls:
If a Tree Falls Into Your Home
- Get everyone safely out of your house. Use your cellphone or go to a neighbor’s house and call 9-1-1.
- Stay away from the home until public safety employees can access your home for structural safety (as well as ensuring your utilities are OK or should be turned off.)
- Only after all of these safety measures should you then call your insurance company.
If a Tree Falls on a Road or Other Land
It does matter where a tree falls:
- Adjacent to Public Roads: Contact Virginia Department of Transportation at 1-800-FOR-ROAD (TTY 711).
- On County Parkland: Contact Fairfax County Park Authority at 703-324-8594 (TTY 703-324-3988).
- Posing Hazard to Public Areas: Contact Fairfax County Urban Forestry at 703-324-1770 (TTY 703-324-1877).
- On Private Property: Removal is the property owner’s responsibility.
If a Fallen Tree Puts Downed Power Lines on Your Car
Always avoid downed power lines. However, if you are driving and a fallen tree causes downed power lines to come in contact with your car, you should take these safety steps:
- Call 9-1-1 and stay in the car until help arrives.
- However, if staying in the car puts you in physical danger, for instance the car is on fire, follow these steps:
- Open the door and avoid touching the framework.
- Jump out of the car as far as you can.
- Use short shuffling footsteps until you are clear of the area.
And after the storm passes, avoid tree trimming scams that are rampant in our community.

Fairfax County and the surrounding areas have received a lot of rain in the past 24 hours, and while the intensity has decreased, rain is still falling in certain areas and roadways are wet, which affects your ability to quickly stop your vehicle during your afternoon commute.
Here are some safety tips to keep in mind this afternoon and evening as you travel.
First, turn on your headlights and your windshield wipers. Your wipers are obvious, but unfortunately, many of us forget to turn on our headlights, which helps us be seen by others on these overcast, grey rainy days.
Once in your vehicle and on your way, remember to give yourself plenty of space around other vehicles. AAA Mid-Atlantic suggests on three-lane roads to drive in the middle lane. They say that most roads are higher in the middle, which means there’s a greater chance of water runoff and standing water in the side lanes.
Be sure to slow down when you see water standing on the surface of the pavement, especially on freeways. Also, drive in the tracks left by any vehicle ahead.
If hydroplaning does occur, do not brake. Instead, ease your foot off the accelerator to gradually decrease speed until your tires regain traction, and continue to look and steer where you want to go. In fact braking in wet conditions is tricky business. Sudden, hard or prolonged braking can cause a skid.
If your vehicle is equipped with anti-lock brakes (ABS), all you need to do is press the brake pedal and hold it down. Do not pump the brakes, because ABS does that very rapidly for you. The system automatically senses if a wheel begins to lock and quickly releases and reapplies the brakes as many times as necessary to keep the wheel from locking up.
If your vehicle is not equipped with anti-lock brakes, the best way to brake under these conditions is to use squeeze braking. For squeeze braking, keep your heel on the floor and use your toes to apply pressure on the brake pedal. If the wheels lock, ease off the brake pedal to a point where they just release. Adjust pedal pressure as necessary. This gives you the best combination of braking effort and directional control.
Flood Warning and Flash Flood Watch
The National Weather Service has extended the Flood Warning for Fairfax County until 9 p.m. tonight and a Flash Flood Watch remains in effect through late tonight.
Rapidly moving water is powerful and can be a threat to vehicles as well as people and property. Please stay away from rapidly rising creeks and streams and don’t drive through roads covered in water. You can’t tell how deep the water may be, so remember to turn around, don’t drown.
Weather information is online at www.fairfaxcounty.gov/emergency/weather-forecast.htm.
Posted at 2 p.m.
The National Weather Service has issued a Flash Flood Warning until 4:15 p.m. this afternoon for Fairfax County and other portions of Northern Virginia.
At 1:17 p.m., NWS Doppler radar indicated very heavy rain capable of producing flash flooding. Up to three inches of rain has fallen in the last 24 hours. Additional rainfall amounts of up to 1 inch can be expected.
Please remember to turn on your headlights anytime you turn on your wipers, but also if it’s overcast or rainy — like today. The short video below from the California Department of Motor Vehicles does a good job of showing why you need to turn on your headlights. Plus, it’s also the law!
Posted at 11:55 a.m.
The National Weather Service has issued a Flood Warning for Fairfax County until 3 p.m. this afternoon.
A flood warning means that flooding is imminent or has been reported. Stream rises will be slow. However, you should take necessary precautions immediately.
Most flood deaths occur in automobiles. 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. When encountering flooded roads make the smart choice – turn around, don’t drown. Bruce McFarlane with our Emergency Management Office offers this advice.
And please keep your children inside and away from streams and creeks.
Our emergency management office, in consultation with NWS, reports that anywhere from 1.25 to 2 inches of rain had fallen across Fairfax County this morning with another 1.5 inches of rain expected between noon and 6 p.m. Rainfall totals should approach 5-6 inches over the course of the storm.
Huntington and Belle View/New Alexandria
For residents in the Huntington area, there could be some street flooding sometime today. County officials also report that residents in the Belle View/New Alexandria area could experience localized street flooding today. You should continue to move your vehicles to higher elevations if you have not already done so.
Fairfax County’s public works and emergency management officials do not anticipate any structural flooding at this time in either of these communities, but staff are continuing to monitor the storm — including our Emergency Operations Center — and will provide updates to residents if conditions change. Be sure to sign up for weather alerts to ensure that you receive these messages.
