Flash Flood Warning Issued

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…

* UNTIL 415 PM EDT

* AT 117 PM EDT… NATIONAL WEATHER SERVICE 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.

* SOME LOCATIONS THAT ARE AFFECTED BY THE HEAVY RAIN INCLUDE ANNANDALE… ARLINGTON… BALLSTON… BULL RUN… BURKE… CENTREVILLE… CHANTILLY… DALE CITY… GREAT FALLS… HERNDON… LAKE BARCROFT… LAKE RIDGE… LINCOLNIA… MCLEAN… MERRIFIELD… OAKTON… RESTON… ROSSLYN… SPRINGFIELD… THE I395 AND I495 INTERCHANGE… THE I66 AND I495 INTERCHANGE… TYSONS CORNER… VIENNA… WOLF TRAP… BETHESDA… CHEVY CHASE… POTOMAC… TAKOMA PARK… THE AMERICAN LEGION BRIDGE… ADAMS MORGAN… AMERICAN UNIVERSITY… GEORGETOWN… MANTUA AND PIMMIT HILLS.

MOST FLASH FLOOD DEATHS OCCUR IN AUTOMOBILES. NEVER DRIVE YOUR VEHICLE INTO AREAS WHERE WATER COVERS THE ROAD. FLOODWATER USUALLY IS DEEPER THAN IT APPEARS. JUST ONE FOOT OF FLOWING WATER IS POWERFUL ENOUGH TO SWEEP VEHICLES OFF THE ROAD. MAKE THE SMART CHOICE WHEN FLOODED ROADS ARE ENCOUNTERED… TURN AROUND… DONT DROWN.

Sewage Release Prompts Stream Warning

By ARLnow.com

Four Mile Run (file photo)(Updated at 3:5o p.m.) Arlington County is warning residents to keep themselves and their pets out of three streams following a sewage release.

The sewage release was the result of a blocked 12 inch sewage pipe, in the area between the Dominion Plaza Apartments (1200 S. Courthouse Road) and the Arlington Village Condominiums (1400 S. Barton Street), near Columbia Pike.

Crews have successfully cleared the blockage and stopped the flow of raw sewage into Arlington Branch, according to the Arlington Department of Environmental Services.

The county says people and pets should avoid Arlington Branch, Lower Long Branch and Four Mile Run until further notice.

“Residents should not fish in the streams or have any contact with the waters — including wading or swimming,” the county said in a press release (below). “The advisory to avoid all contact is considered an extra precaution to allow the effect of the discharge to be diminished by natural flushing of the streams.”

Arlington County today advised residents to avoid water downstream of a sewage release that occurred between the Dominion Plaza Apartments and Arlington Village Condominiums, just above the Army Navy Country Club into Arlington Branch, a tributary to Lower Long Branch. Arlington Branch, Lower Long Branch and Four Mile Run from Columbia Pike downstream to the Potomac River should be avoided. This is a precautionary measure following the discovery of a sewage release resulting from a blocked 12” sewage pipe. Water, Sewer, Streets crews are actively working to remove the blockage from the pipe and stop the release.

Residents are advised to stay away from the affected waters and to keep their pets away until further notice, to eliminate the risk of exposure to untreated sewage. Residents should not fish in the streams or have any contact with the waters – including wading or swimming – until further notice from the County. The advisory to avoid all contact is considered an extra precaution to allow the effect of the discharge to be diminished by natural flushing of the streams.

Recreational areas affected adjacent to the streams include Fraser Park, Troy Park and Four Mile Run Park.

NOTE: Residents are reminded that stream water can contain microorganisms that can make people sick, whether the stream is located in an urban area or in the middle of a forest. Even after the discharge is naturally flushed from the streams, the County’s normal precautions for safe use of streams apply. You can find information and safety tips on Arlington streams, including information on reporting stream pollution incidents, on the Department of Environmental Service website.
