Yesterday’s Winter Storm Watch has been upgraded to a Winter Storm Warning.
The winter storm that has been causing major problems in Texas and the central U.S. is making its way towards the D.C. area on its march up to New England. It’s expected to drop 3-6 inches of snow on Arlington and the immediate D.C. area before the precipitation switches to sleet and freezing rain.
The ice accumulation could cause dangerous road conditions and power outages, forecasters and local officials warn.
“With heavy snow, sleet, freezing rain and ice in the forecast for Northern Virginia on Thursday and Friday, significant road impacts are expected,” the Virginia Dept. of Transportation said today. “While VDOT crews prepare to deploy, residents are asked to closely monitor weather updates and plan ahead to avoid nonessential travel tomorrow and Friday.”
“Crews will finish pre-treating about 2,000 lane miles of interstates and primary routes in Arlington, Fairfax, Loudoun and Prince William counties today,” VDOT added. “Drivers are asked to be alert to brine tankers and to give them room, as they move slowly to spray the salt water solution on the pavement. Pretreatment will help prevent ice from bonding to assist crews with snow and ice removal at the storm’s onset.”
Arlington County crews are also currently pretreating local roadways.
A Winter Storm Warning was issued for the region this morning. More from the National Weather Service:

Despite temperatures expected to reach 50 degrees today, Arlington is mere hours from the start of a winter storm with snowfall that may exceed that of last weekend.
A Winter Storm Warning has been issued for Arlington and surrounding communities, with forecasters calling for 3-6 inches of accumulation. The warning is in effect from 3 a.m.-noon on Super Bowl Sunday.
Periods of heavy snow are expected Sunday morning, making travel treacherous, but warming temperatures should allow those with plans for the big game to get around with few issues later in the afternoon.
Snow crews are getting ready to do battle with the elements once again
“VDOT Northern Virginia crews are ready for a quick-hitting winter storm expected to impact the district early Sunday,” VDOT said today. “Today, crews are pre-treating bridges, ramps, overpasses and other trouble spots throughout Arlington, Fairfax, Loudoun, and Prince William counties, to help prevent ice and snow from bonding to the pavement at the onset of the storm.”
“Residents are asked to monitor forecasts, plan ahead to avoid nonessential travel during the storm, and be aware of the potential for slick spots overnight Sunday.” the transportation agency noted.
The City of Falls Church, meanwhile, is activating its snow emergency routes at 9 p.m. tonight (Saturday).

Update at 4 p.m. — The Flood Warning has now been cancelled.
Earlier: As what remains of Hurricane Zeta drenches the region, Arlington County is now under a Flood Warning, meaning flooding is currently happening or is imminent.
“Observations show we’re crossing the 1.5″ rain total threshold throughout much of the urban corridor,” the National Weather Service said just before noon. “Flooding is going to be slow to develop but we should see increasing reports of it this afternoon.”
Flooding has already been reported west of Arlington in Fairfax County, along Wolftrap Creek and Accotink Creek. The warning is in effect until 5:30 p.m.
In addition to heavy rain, strong winds are expected between roughly 5-8 p.m. this evening as the center of the storm passes the region.
