There were reports of dangerous, icy conditions on roads and walkways in some parts of Virginia and Maryland.

No major delays were noted due to weather conditions on main commuter routes. Some roads in Baltimore County had weather-related crashes.

There was also a minor crash on the inner loop of the Beltway.

In Virginia, parts of western Loudoun County also had icy road conditions. Drivers and pedestrians throughout the area were advised by experts to use caution and allow extra time in their commutes.

Riders on Metro and commuter rail lines faced no major delays. But were warned there could be some crowding on platforms and trains, given the federal government’s two hour delayed opening.

All lanes of northbound Interstate 83 in Baltimore County were closed due to a crash.

The initial report was that the incident was due to possibly icy road conditions. Maryland State Police said several trucks were reapplying salt on parts of the highway.

There were reports of other weather-related crashes in some areas outside of the District.

There were no major weather related crashes or delays on the Beltway or Interstates 66 or 95 at this time.

On the Metro and other commuter rails, there were no reports of major problems. But officials reminded riders to use caution on walkways that may be slippery.

Drivers, pedestrians and cyclists are advised to use caution, slow down and allow extra time in Wednesday morning’s commute, as there may be slick spots on roads, bridges and sidewalks.

There were no major incidents on any of the major roadways in the D.C. region in the early morning hours.

Even with almost no snow, rain or ice on the ground in the early morning hours, the federal government was opening two hours late. Many area school districts had delayed openings or were closed.

The Capital Weather Gang’s forecast said they expect light precipitation. But there is concern that temperatures — now in the 30s — could cause rain to freeze on roads, bridges, sidewalks.

By 7 a.m., forecasters said there could be spotty precipitation that could make for slippery conditions in parts.

The National Weather Service forecast freezing rain to spread over the area in the rush hour from southwest to northeast. A “glaze of ice” is expected for some areas south and east of the District with possible .2 to .3 inches of ice, the Weather Service said.

It also said that there could be a “glaze of ice, or at least icy spot” on doorsteps, sidewalks and driveways. Some areas in the region, the NWS said, were seeing “freezing drizzle” but the weather radar was not showing any precipitation because the “drizzle drops are too small for the radar to see.”

Area transportation and police departments warned drivers to use caution and allow extra time as the morning rush hour gets into full swing. Even roads just look wet, officials said, there can still be slick spots — given the low temperatures.

In the District, the temperatures on some area roadways were near the freezing mark.

Drivers should allow crews and trucks plenty of room for treating roads.

And pedestrians should be careful, as slips and falls are more frequent in bad weather, officials said. Local police and fire agencies recommend pedestrians should walk similar to a penguin. Keep the center of gravity over your front leg. Just as a penguin waddles, changing your center of gravity will keep you upright.

Use caution, experts say, when walking on slick or icy spots. Spread your feet out and waddle like a penguin is recommended to change your center of gravity. (Courtesy of the Today Show)

If you feel yourself slipping, don’t put your arms or wrists out to catch yourself. You could end up breaking your wrists or arms, experts warn. Safety experts recommend that you instead try to land on the fleshy part of your body and not your spine or knees.
