PORTLAND — An unexpected snow squall that coated parts of Maine with up to an inch of snow is creating slippery roads and scores of minor traffic accidents this morning.

As of mid-morning, police hadn’t reporting any serious injuries, but had responded to various slide-offs and fender benders around the region.

Much of the trouble was being reported along the Midcoast, from Topsham to Wiscasset and Boothbay Harbor. Multiple reports were coming from routes 1 and 27.

“We have a cold front dropping through the area now,” said Chris Legro, a meteorologist at the National Weather Service in Gray.

The cold air colliding with warmer air set off heavy snow showers in some locations. The snow is expected to end shortly, and the cold air spilling into Maine wil begin to drop temperatures later this afternoon, Legro said.
