Flooded Four Mile Run (photo courtesy @gogogaryo)A Flash Flood Warning has been issued for Arlington and much of the rest of the D.C. region. The National Weather Service warns that nearly 3 inches of rain has fallen already today and more heavy rainfall is on the way.

Standing water on roadways has created some dangerous driving conditions in Arlington, and swollen local waterways like Four Mile Run are starting to resemble “class three rapids,” but otherwise few serious problems have been reported around the county so far.

It’s a different story elsewhere in the region. In Montgomery County, cars and their drivers are getting trapped in high standing water.

From the National Weather Service:

THE NATIONAL WEATHER SERVICE IN STERLING VIRGINIA HAS ISSUED A

* FLASH FLOOD WARNING…

Rainy accident on I-395 at Washington Boulevard (file photo)Numerous accidents have been reported around Arlington today as continued rainy weather is making for slick conditions on the roads.

AAA Mid-Atlantic is reminding motorists to drive carefully in wet weather.

The association sent out the following press release this afternoon.

As the coastal storm continues through the Washington metro area today, motorists will face hazardous driving conditions during their evening commute due to rain and standing water, warns AAA Mid-Atlantic.  The auto club is advising motorists to exercise caution when driving.

“Commuters heading home tonight will face the same hazardous weather conditions as this morning’s drive to work,” said John B. Townsend II, AAA Mid-Atlantic’s Manager of Public and Government Affairs.  “When driving in wet weather remember to buckle up, slow down, and keep a safe distance from the car in front of you. Also, remember, it’s the law in the District of ColumbiaMaryland and Virginia to turn your headlights on if your windshield wipers are in use.”

To minimize the hazards associated with wet weather driving, AAA Mid-Atlantic recommends the following precautions for navigating in heavy rain, reduced visibility and slick pavement:

  • Slow down and increase following distances. Speed limits are set for ideal road conditions. When it rains, visibility is reduced and braking distances increase. On dry pavement, a safe following distance permits two to three seconds for stopping; that should be increased to eight seconds on slippery roads. Train your eyes farther down the road than normal, so you can anticipate changes and adjust your course gradually.
  • Do not attempt to drive through standing water on the roads that look too deep. Avoid bridges and roads that are known to flood. When driving on pothole-filled roads, hold the steering wheel firmly to avoid losing control. Just a few inches of water can turn your vehicle into a boat, and could put your life, and the lives of those around you, at great risk. Turn around; find another way to get to your destination.
  • Watch out for hydroplaning. No car is immune from hydroplaning on wet surfaces, including four-wheel drive vehicles. Just because brakes work under normal conditions doesn’t mean they will react the same on slippery roads where tires roll with far less traction.
  • Alert drivers behind you that you’re slowing with your brake lights. Without anti-lock brakes, squeeze the brakes until they are about to lock up and then release. With anti-lock brakes, use the same move – but don’t pump the brakes, which would work against the operation of the ABS system. Slow down as you approach a pothole. However, do not brake when your vehicle is directly over a pothole.
  • Use the central lanes. When driving during heavy rain, use center lanes of the road (without straddling the yellow line). Avoid outside lanes where the water collects at curbside.
  • Use low-beam headlights to help other drivers see your car and increase visibility.
  • Use your defroster with your air conditioning to keep the air dry and prevent windows from fogging.
  • Do not drive around barricades. Many lives have been lost when drivers disregard official orders and find themselves trapped in rising waters.
  • Turn off the cruise control in wet weather driving. The use of cruise control on wet roads can cause hydroplaning.
  • If conditions worsen to the point where there is any doubt about your safety, take the nearest exit and find a safe location.  Don’t just stop on the shoulder or under a bridge where you may feel less anxiety. If your visibility is compromised, other drivers may be struggling too.
  • Watch for slick spots on the road. Fumes and oil leaks that build up on dry pavement rise to the surface of the road when it rains, making the road far slicker than it may seem.

Update at 9:35 a.m. — Departing flights are experiencing a “gate hold” at DCA. Delays of at least 30 minutes should be expected, and could get worse throughout the day.

Update at 8:55 a.m. — There is a ground stop for flights arriving at Reagan National Airport due to the weather. Check with your airline for the status on any outgoing flights.

The National Weather Service has put Arlington and the rest of the metro area under a Severe Thunderstorm Watch until 11:00 a.m. That’s in addition to the Flash Flood watch that went into effect at midnight and will last until 8:00 p.m.

NWS notes several rounds of strong storms could soak the area. That could create trouble due to the level of ground saturation from the heavy rains that caused flooding earlier this week. From NWS:

* SHOWERS AND THUNDERSTORMS WILL LIKELY MOVE ACROSS THE REGION
THIS MORNING AND PRODUCE HEAVY DOWNPOURS. RAINFALL AMOUNTS IN
EXCESS OF 1 INCH ARE POSSIBLE. ANOTHER ROUND OF STORMS MAY BRING
HEAVY RAIN THIS AFTERNOON AND EVENING WITH AN ADDITIONAL 1 TO 2
INCHES POSSIBLE.

* WITH THE GROUND ALREADY SATURATED FROM HEAVY RAINFALL DURING
THE PAST WEEK…ONLY AN INCH OF RAINFALL IN AN HOUR COULD
PRODUCE FLASH FLOODING OF STREAMS AND LOW LYING 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.

Although the storms have the potential to bring damaging winds and the word “derecho” is being thrown around, the Capital Weather Gang doesn’t expect it to be as strong as the derecho that struck last year.

The Office of Personnel Management has kept all federal offices open, but employees have the option of unscheduled leave or unscheduled telework.

Rainy Reflections (photo by Katie Pyzyk)Arlington has been feeling the impacts of Tropical Storm Andrea today.

The storm has been dumping rain on the region all day, and even heavier rains and stronger wind gusts are expected during the evening commute.

Tonight’s outdoor showing of “Risky Business” in Rosslyn has been cancelled due to the weather. Meanwhile, the soaking rains and wind might be responsible for knocking down power lines along N. Pershing Drive in the Ashton Heights area. Pershing is currently closed between Lincoln and Monroe Streets while police and firefighters wait for Dominion Power crews to repair the lines.

AAA Mid-Atlantic is warning drivers to be careful on the roads tonight, especially during periods of heavier rain.

“Tropical Storm Andrea passes through the Washington Metro area today and will continue north along the I-95 corridor,” the organization said in a press release. “Motorists will face hazardous driving conditions during the evening commute due to heavy winds, torrential rains, and flooding… The auto club is advising motorists to exercise caution if they must take to the roads during the squally driving conditions.”

AAA issued the following list of wet weather driving tips.

  • Slow down and increase following distances. Speed limits are set for ideal road conditions. When it rains, visibility is reduced and braking distances increase. On dry pavement, a safe following distance permits two to three seconds for stopping; that should be increased to eight seconds on slippery roads. Train your eyes farther down the road than normal, so you can anticipate changes and adjust your course gradually.
  • Do not attempt to drive through standing water. Try to avoid bridges and roads that are known to flood. Cross them only if there is little standing or streaming water. When driving on pothole-filled roads, hold the steering wheel firmly to avoid losing control. Just a few inches of water can turn your vehicle into a boat, and could put your life, and the lives of those around you, at great risk. Turn around; find another way to get to your destination.
  • Watch out for hydroplaning. No car is immune from hydroplaning on wet surfaces, including four-wheel drive vehicles. Just because brakes work under normal conditions doesn’t mean they will react the same on slippery roads where tires roll with far less traction.
  • Alert drivers behind you that you’re slowing with your brake lights. Without anti-lock brakes, squeeze the brakes until they are about to lock up and then release. With anti-lock brakes, use the same move – but don’t pump the brakes, which would work against the operation of the ABS system. Slow down as you approach a pothole. However, do not brake when your vehicle is directly over a pothole.
  • Use the central lanes. When driving during heavy rain, use center lanes of the road (without straddling the yellow line). Avoid outside lanes where the water collects at curbside.
  • Use low-beam headlights to help other drivers see your car and increase visibility. Remember many states legally require drivers to use their headlights during inclement weather. In our neck of the woods Virginia, Maryland, Delaware, Pennsylvania, and New Jersey have wipers on, lights on laws, according to the AAA Digest of Motor Laws.
  • Use your defroster with your air conditioning to keep the air dry and prevent windows from fogging.
  • Do not drive around barricades. Many lives have been lost when drivers disregard official orders and find themselves trapped in rising waters.
  • Turn off the cruise control in wet weather driving. The use of cruise control on wet roads can cause hydroplaning.
  • If conditions worsen to the point where there is any doubt about your safety, take the nearest exit and find a safe location. Don’t just stop on the shoulder or under a bridge where you may feel less anxiety. If your visibility is compromised, other drivers may be struggling too.
