Winter Weather Advisory in Effect Beginning at 6 p.m.

Posted at 1 p.m.

The National Weather Services has issued a Winter Weather Advisory in effect from 6 p.m. tonight, Thursday, Jan. 17, until 4 a.m. Friday, Jan. 18 for Fairfax County, the District of Columbia and central and Northern Maryland. A winter weather advisory for snow means periods of snow will cause primarily travel difficulties. Expect snow covered roads and limited visibilities, and use caution while driving.

Snow will develop late this afternoon into this evening and continue into the overnight hours. While accumulations are forecast to be light, around an inch, any untreated road surfaces and sidewalks may turn icy as temperatures fall below freezing after sunset.

According to the weather service, the greatest threat for impact from this light snowfall during the evening rush hour will be north and west of Interstate 95 from Baltimore to Fredericksburg and also near Interstate 66 in Northern Virginia.

If you plan on commuting this evening, be aware of the potential for travel disruptions. Plan ahead by allowing for extra travel time and consider using public transportation and telework options. You should plan on slippery road conditions and sidewalks.

Snow Update: Sunday, Jan. 13; Some County Facilities Affected

Posted at 10 a.m.

The National Weather Service reports that Fairfax County has already received approximately 4-5 inches of snow — totals are approximately one inch higher toward the western portions of the county — and that we could receive up to an additional 3-4 inches today.

The winter storm warning continues until 6 p.m. A winter storm warning for snow means severe winter weather conditions will make travel very hazardous or impossible.

If you absolutely must drive, stay as far behind plows as possible, and significantly reduce speeds. Plow trains — staggered plows spanning all lanes of the road — are actively working interstates and need room to safely work. And as a reminder, the Virginia Department of Transportation plows most roads in Fairfax County. Visit our snow guide to view VDOT updates, its snow plow tracker and more.

County Facilities

The snow has forced some closings and cancellations for county agencies. Here’s the latest:

Safety Measures

If you are out shoveling your sidewalks or driveways, remember that heavy wet snow can put a strain on your heart. Only shovel if you are physically able to.

  • Shovel small amounts with each shovel pass.
  • Stay hydrated.
  • Take frequent breaks.

And this video from VDOT explains how to properly shovel your driveway.

Fire Hydrants

The snow accumulations, combined with the after-effects of plowing roads may result in fire hydrants being partially, or completely, buried in snow. It is vital that firefighters be able to quickly access a hydrant in the event of a fire. Immediate access to a water supply helps to swiftly extinguish the fire and prevent loss of life and property.

All residents, who are physically able to do so, are asked to keep the nearest fire hydrant accessible and free of snow and ice. Please clear a three-foot area around the hydrant and ensure there is a path to the roadway so the hydrant is visible and easily accessible.
