Road crews have been out for several hours.
The snow emergency plan is in effect for Frederick and Washington Counties as an early spring storm is dumping several inches of snow in the area.
Bill Routzahn, Superintendent of Frederick County Highway Operations, said his crews have been out for several hours.
"It started snowing at 3 a.m. and we called our crews out at 4 a.m. Once the snow started coming down, the western side of the county got covered up really fast."
He added that they are applying salt where it is needed.
Routzahn is urging drivers to be cautious today.
Forecasters say we could get between 3 to 5 inches of snow before the storm moves out.
