(Updated at 1:30 p.m.) Snow is falling in Arlington and roads have quickly become snow-covered, making travel hazardous.

Several accidents have already been reported around the county during the snowfall. Arlington County is advising residents to stay off the roads “unless absolutely necessary.”

“Roads in Arlington are snow covered and blocked in many areas,” the county said in an Arlington Alert email. Road conditions are also considered to be treacherous. Do not go on the roads unless absolutely necessary.”

Police are shutting down a ramp from eastbound Route 50 to N. Courthouse Road due to especially slippery conditions. Several cars have reportedly gotten stuck on the ramp and the Courthouse Road hill. More problems are being reported at the intersection of Lee Highway and N. Danville Street, and elsewhere.

VDOT is also urging drivers to stay off the roads.

Extremely treacherous out there. Please stay off roads.

People should only be on the roads if it is an extreme emergency.

VDOT says it will have 1,400 trucks clearing snow in Northern Virginia today. It did not pre-treat roads due to low temperatures, which renders road salt ineffective.

Arlington community centers, libraries and schools will all shut down at 1:00 p.m. due to the snow. The Arlington County Board, which has a meeting current in progress, is planning to end its meeting early and defer its last action item until Tuesday.

The National Weather Service has issued a Winter Weather Advisory, calling for 2-4 inches of snow — the Capital Weather Gang says 5 or more inches is possible — before a warm-up that turns the precipitation into sleet, freezing rain and then plain rain.
