Heavy Snowfall Forecast for Maryland Wednesday

(March 20, 2018) – Maryland Department of Transportation State Highway Administration (MDOT SHA) crews are prepared for the possibility of accumulating snowfall Tuesday night and Wednesday. The storm system that is developing could produce hazardous conditions for drivers Wednesday morning.

Pavement temperatures Tuesday afternoon are mostly remaining in the mid-upper 30’s, but areas north and west are just above freezing. Motorists are urged to reduce speeds and be especially cautious on elevated roadways (bridges, ramps and overpasses). 

When a storm is forecast to produce 6 or more inches of snow, MDOT SHA makes available for drivers some park and rides that are wide enough to accommodate large vehicles.
