Winter Storm Leaves Potentially Hazardous Icy Conditions in DC Area

Flood watches issued for parts of the region

NBC Universal, Inc. Storm Team4 Chief Meteorologist Doug Kammerer has the forecast.

A picturesque Wednesday morning with big, white snowflakes quickly turned to rain and slush, and now the big concern is ice.

Ice is coating trees and potentially roads, which could create some hazardous driving conditions Thursday morning. Falling tree limbs are possible, potentially causing power outages.

Avoid driving until at least mid-morning if possible, Storm Team4 Meteorologist Amelia Draper advised.

Several area school districts are closed Thursday or on all-virtual learning.

Federal agencies in the region will delay opening until 10 a.m., according to the U.S. Office of Personnel Management. Agencies can offer employees unscheduled leave or remote work.

Virginia was hit with a blast of wintry weather today, making for treacherous conditions on the roads. News4's Darcy Spencer talks with people who were out braving the elements.

Flurries of snowflakes began falling across D.C., Maryland and Virginia on Wednesday morning, kicking off the first winter storm of the season. Snow was still falling to the west of D.C. in the Leesburg and Frederick areas and along Interstate 68 near Cumberland, Maryland, late Wednesday, but in the metro area, snow had long since changed over to a cold rain or wintry mix.

Public schools in Prince William, Loudoun and Culpeper counties will be closed Thursday. Virtual learning is canceled.

Spotsylvania County Public Schools are closed Thursday, but content for students to study will be available online.

At least 30 car accidents were reported in an eight hour period due to the storm, including two involving pedestrians, according to Montgomery County Fire and Rescue. News4's Jackie Bensen reports on Wednesday, Dec. 16, 2020.

Several school districts will offer all-virtual learning, including Arlington, Fairfax and Stafford counties.

"It's a big storm no matter what," Storm Team4 Meteorologist Chuck Bell said.

Precipitation is likely to continue until about 6 a.m. Thursday. Storm Team4 has declared a weather alert.
