WASHINGTON — WTOP traffic reporter Bob Marbourg said it’s not the time for exceeding the speed limit, as wet roads turned icy overnight. A statement by the National Weather Service advised motorists and pedestrians to exercise extreme caution when driving or walking Saturday morning, and to reduce speed, leave extra stopping distance, and allow plenty of extra time when traveling. WTOP’s traffic center reports several crashes on Saturday morning, particularly on bridges, ramps and overpasses, which are the first to freeze. See the latest traffic updates here. Although the area only had a light dusting Friday, NBC Storm Team 4 meteorologist Doug Kammerer warned that any wetness left would turn icy, as temperatures dropped below freezing, making roads, sidewalks and driveways slippery. Kammerer said to expect plenty of black ice.

Happy Saturday! While the sunrise is pretty, the icy patches on some roads are not, so be careful until temperatures rise above freezing later this morning. #dcwx #mdwx #vawx #wvwx pic.twitter.com/jHE3sWxUDF

A mix of snow with graupel mixed in fell Friday and moved out of the area by 6 p.m. Graupel is snow coated in supercooled liquid. This precipitation typically forms when the lower atmosphere is unstable. The Friday afternoon rush got started several hours early as drivers tried beat the snow and early dismissals for several counties in Maryland put more vehicles on the road in the early afternoon.
