Greater Portland begins the week with at least a few inches of new snow.

An overnight storm has dropped snow in the Casco Bay area and York County into interior western and central Maine and the midcoast

James Brown, a meteorologist at the National Weather Service in Gray, said the heaviest accumulations would stay along the coastline.

“This is a coastal system, you are going to see the most in southern Maine and coastal areas, but it tapers off when you come into the mountains,” Brown said.

The storm should pull away by midmorning Monday in the Portland area, he added.

The Portland Police Department warned that roads were slick and reported several accidents by 6 a.m. Monday morning.

The department warned commuters to drive slowly, leave room between cars and clean off their vehicles before departing.

According to North Yarmouth Fire Rescue, Route 231 is closed at the New Gloucester-Gray-North Yarmouth town lines because of a crash in North Yarmouth. The road will be closed until further notice and motorists are advised toe seek alternative routes.

The remainder of the week is expected to be clear and cold, with the next weather system developing by the weekend.
