WASHINGTON (AP) — Transportation officials around the mid-Atlantic region are warning motorists to take care and watch for black ice a day after a spring snowstorm hit the region.

Officials are urging motorists to lower their speeds Wednesday morning since most roads are clear, but melted snow may have frozen overnight.

Reports to the National Weather Service show southern Delaware got the most snow in the region, around 6 inches in parts of Sussex County. In northern Delaware, snowfall amounts were less than 1 inch.

In northern Virginia, 3.8 inches was reported at Dulles International Airport by Tuesday evening and 1.7 inches was reported at Reagan National Airport.

In Maryland, around 4 inches was reported in Howard and Montgomery counties, but just .2 inches was reported at Baltimore-Washington International Thurgood Marshall Airport.
