Update Issued For VA Winter Storm: See Latest Timing, Snow Totals

Forecasters warn the snow could mix with sleet and freezing rain, causing treacherous travel conditions and potential power outages in VA.

A winter storm warning remains in place in Virginia from Saturday night through Monday morning as forecasters predict several inches of snow and ice could blanket the Washington, D.C. region. Virginia officials have declared a state of emergency ahead of the storm.

In a new storm forecast released Saturday morning, the National Weather Service said the D.C. region will likely see less snowfall than originally anticipated. Regardless, the storm will still have significant impacts across the state and dangerous ice remains a concern.

"A large area of precipitation will overrun Arctic air in place over the Mid-Atlantic, which will lead to widespread significant snow beginning Saturday evening, with the potential for ice Sunday, especially south of Highway 50 and near and east of Interstate 95," National Weather Service forecasters wrote. "Power outages and tree damage are likely due to the ice. Travel could be nearly impossible."

A winter storm warning is in effect for the entire state. In Northern Virginia, the warning goes into effect at 11 p.m. Saturday until 4 a.m. Monday.

According to the National Weather Service, snow will likely spread across the region Saturday night, becoming heavy at times with rates of 1 to 2 inches per hour possible.

A mix of sleet or freezing rain is expected on Sunday. Significant icing is possible, especially south of Highway 50. Visibility of one-quarter mile or less is possible at times.

The National Weather Service said the region will likely see total snow and sleet accumulations between 7 and 14 inches, with the highest amounts in the far northern and western suburbs of Washington, D.C. and Baltimore. Ice accumulations between one and two tenths of an inch are expected, but areas south of D.C. could see close to 0.25 inches.

If freezing rain accumulates to more than 0.25 inches, impacts could become significant.

"The weight of freezing rain can snap tree limbs and power lines, leading to power outages," The Washington Post's Capital Weather Gang wrote. "Most projections for the Beltway area suggest 0.1 to 0.3 inches, but some areas could see more — particularly from around Fredericksburg into Southern Maryland, where the risk of disruptive amounts of ice is growing."

Travel will be hazardous to near impossible, and at times may be life-threatening, throughout the weekend, said state officials.

In addition to snow and ice, a prolonged period of wind chills in the teens and single digits is expected to continue Saturday evening and last through the middle of next week, with sub-zero wind chills possible at times.

Cold weather advisories were also issued across much of the area and are expected to expire at noon Saturday.

On Thursday, Virginia Gov. Abigail Spanberger declared a state of emergency ahead of this weekend's winter storm, which allows for state agencies and resources to be on standby across the Commonwealth.

"I am asking all Virginians to spend this time getting prepared for this incoming storm and to stay off the roads," Spanberger said. "This will allow not only for the safety and security of our neighbors, but for faster clearing of roads and ensure greater safety during what we expect will be the most dangerous times on the roads."

VDOT said crews will begin plowing once two inches of snow has fallen. The priority order for snow removal is interstates, primaries, secondaries, and eventually neighborhood roads.

VDOT Northern Virginia also did a full pretreatment of the roads with salt brine on Friday. Brine helps prevent the bonding of snow and ice to the pavement at the beginning of a storm, allowing crews time to respond.
