BANGOR, Maine — The number of school, state and event cancellations began rising early Monday evening as Maine braced for a storm expected to bring a mix of snow, sleet and freezing rain late Monday night into Tuesday evening.

National Weather Service forecasters said Monday that the storm will arrive in southern reaches of the state late Monday night, mostly in the form of snow.

The snow, however, could mix with or change over to sleet overnight as temperatures rise above freezing.

Central Somerset County could see 5 to 8 inches of snow between 4 a.m. and 7 p.m. Tuesday.

Also expected to be hit hard are most of Aroostook and Piscataquis counties and northern Somerset County, where snow and sleet accumulations of 3 to 6 inches are possible, as well as a trace of accumulated ice.

Southeast Aroostook county is expected to get 3 to 5 inches of snow and sleet and as much as a quarter of an inch of ice, forecasters said.

They said Penobscot and parts of Washington and Hancock counties will see sleet and rain, with the potential for 1 to 3 inches of sleet and ¼ inch to ½ inch of ice.

Meanwhile, the rest of the state is under a winter weather advisory.

As of about 9 p.m. Monday, about 40 schools, businesses, municipal offices, churches and events had been canceled — including all state legislative sessions, public hearings and work sessions scheduled for Tuesday.

Forecasters said that motorists should be prepared for dangerous travel conditions. In addition, they said, ice could bring down trees and cause branches to snap, which may lead to power outages.
