LANHAM, Md. (WNEW/AP) — The Winter Weather Advisory expired at 10 a.m. Tuesday for both D.C. and Baltimore, as snow and freezing rain headed to the region, the National Weather Service said.
Plummeting overnight temperatures will cause some slick roads in many areas of the region.
Commuters saw mostly slippery roads with patches of ice in Maryland, D.C. and northern Virginia Tuesday morning.
The National Weather Service said snow was expected to taper off around mid-day as temperatures climb above freezing.
State Highway Administration (SHA) crews will continue to patrol through Tuesday afternoon to treat roads refrozen or covered in additional snow and freezing rain.
SHA is urging drivers to avoid unnecessary travel as pavement temperatures hover below the freezing mark and icy conditions are possible.
Temperatures will be in the upper 30s and wind gusts will reach up to 25 miles per hour Tuesday.
With many roads still damp, temperatures will drop into the teens overnight Tuesday.
Bob Sager, spokesman for the Maryland Highway Safety Authority, said the roads were wet early in the evening Monday, but overnight as temperatures dropped, icy patches formed.
Sager said crews were deployed to salt roads across the state.
A winter storm dumped an inch or two of snow across much of central and eastern Virginia, forcing many schools to close.
Virginia Department of Transportation crews were out in force, treating slippery highways and roads. Officials urged motorists to allow extra time to reach their destination.
Virginia Department of Transportation spokesman Mike Murphy said significant portions of major highways and roads in Loudoun County were covered in snow by 8 p.m. Monday.
Murphy said roads in Prince William and Fairfax counties were in slightly better condition, but motorists should still be conscious of patches of ice as temperatures drop overnight.
NWS meteorologist Howard Silverman said Monday night that snow in Maryland and Washington would continue to accumulate until between midnight and 2 a.m.
Silverman said both areas are expected to get between 1-3 inches of snow in total, although western Maryland, Allegheny County in particular, could see up to 8 inches of snow accumulate on the ground by Tuesday morning. That’s largely due to residual snowfall from Sunday night.
D.C. Mayor Bowser’s administration has activated the city’s Cold Emergency Plan, to take effect Monday evening and extend through the early morning hours of Tuesday.
When the Cold Emergency Plan is activated, D.C. expands winter shelter capacity by opening warming sites and enhances outreach to homeless residents.
WNEW’s Mark Segraves reports that the districts’ homeless shelters are filling up, as the cold weather continues to hit our area.
There are now more than 1,100 homeless children living with their families in district shelters, and 1,400 single men and women in shelters.
D.C. officials ask individuals who are homeless to request transportation to a shelter or warming site by calling the Shelter Hotline at (202) 399-7093, 211 or 311, or toll free from a payphone at 1 (800) 535-7252.
In Baltimore, the city’s health department announced a Code Blue for Tuesday and Wednesday, when temperatures are expected to dip into the low 20s.
Reagan National Airport is the most affected of the area’s major airports Monday evening, with 175 incoming and outgoing flight cancellations and nearly 160 flights delayed, according to FlightStats.
At BWI more than 70 flights are cancelled and more than 100 delayed. Dulles International Airport is experiencing the least cancellations at 53 flights, but the most delays at more than 180 flights.
Amtrak announced that it planned to suspend service in the New England region on Tuesday. Service between New York and Washington on Monday was modified, and passengers were warned to expect delayed frequencies of trains.
