Maine State Police say troopers have responded to more than a dozen crashes due to snow and black ice on the Maine Turnpike so far Friday morning.
Only minor injuries have been reported.
CBS 13 spotted a car that had crashed into a guardrail in the Wells area on I-95.
A winter storm warning is in place for the mountains for up to 15 inches or more of snow. A winter storm warning is also in place for inland York, inland Cumberland, Kennebec and Androscoggin counties for as much as a foot of snow through Saturday afternoon.
At the coast, where totals are still somewhat uncertain, a winter weather advisory is in place for 2 inches to as much as 7 inches of snow. The large range is due to the changing between rain and snow several times.
