WASHINGTON (WNEW/AP) — Forecasters say a winter weather system moving toward the East Coast may only bring rain to the Washington and Baltimore areas.
Still, a Winter Weather Advisory has been issued for parts of Maryland and Virginia. It went into effect at 6 p.m. Friday and expires at noon Saturday.
The National Weather Service says it has the potential to bring snow, sleet and freezing rain.
The affected areas in Maryland include: Carroll, Howard, Montgomery, Frederick, Harford, Howard County, Baltimore County and Baltimore City.
The affected areas in Virginia include: Loudoun, Fairfax, Prince William County, City of Manassas and Manassas Park.
Anne Arundel, Fauquier, Loudoun, Stafford County and Baltimore City schools canceled all activities on Saturday, including SATs.
Howard County Public Schools canceled activities that begin after 6 p.m. Friday and say if a snow emergency plan is in effect as of 5:30 a.m. Saturday, the SAT will be canceled.
Carroll County Public Schools canceled activities that begin after 6 p.m. Friday as well and say if a snow emergency plan is in effect at 8 p.m. Friday evening or later, all activities will be canceled for Saturday. Saturday School is canceled.
Road crews are being treating city streets and highways ahead of two winter storms approaching the area.
The Maryland State Highway Administration is warning motorists that travel may become hazardous. The agency says it’s preparing for the storms with salt and plows to treat the roads.
The Maryland Transit Administration says it is working to keep buses, trains and cars moving this weekend during the winter weather.
National Weather Service meteorologist Andrew Snyder says the metropolitan areas of Baltimore and Washington will likely sit on the fringe of the storm with more rain than wintry precipitation Friday night into Saturday. Temperatures are likely to hover around the freezing mark or just above.
There may be more snow and lower temperatures in areas north and west of Baltimore and Washington.
Snyder says this is not looking like a major winter storm. He says there could be 1 to 4 inches of snow in areas to the north and west of the metropolitan area.
The highest snow accumulation is expected west of Philadelphia, New York City and Boston.
