Falling temperatures could lead to icy conditions on roads and sidewalks across the Northeast following a late-season storm that plastered the region with sleet and snow.
The Maryland Transportation Authority urges locals to walk and drive carefully, using extra caution on bridges, overpasses, and off-ramps.
"What looks wet will be ice," officials said on Twitter.
The powerful nor'easter paralyzed much of the Washington-to-Boston corridor, but fell short of predicted snowfall totals in New York, Boston and Philadelphia.

The storm, which followed a stretch of unusually mild weather, dumped 1 to 2 feet in many places, grounded more than 6,000 flights and knocked out power to nearly a quarter-million customers from Virginia northward.
By the time it reached Massachusetts, it had turned into a blizzard, with near hurricane-force winds gusting to over 70 mph along the coast.
Plunging overnight temperatures threatened to turn the snow, sleet and sloppy mix into a slippery mess.
Reduce speeds this morning. Use extra caution on bridges, overpasses, on & off ramps and infrequently traveled roads. #mdotnews
