GRAY, Maine — Southwestern and coastal counties were the hardest hit by a snowstorm that moved through on Monday and was expected to linger into Tuesday morning in parts of the state.

According to the National Weather Service’s Gray forecast center, several waves of low pressure tracked along a front that stalled to the south of New England.

Although the potential for more than a foot existed for some areas, the weather service’s unofficial observations showed that as of 2 p.m. — the most recent accumulation totals available Monday evening — Franklin, Oxford, Cumberland, Sagadahoc, Somerset and Lincoln counties each had received roughly half a foot of fresh snow.

Franklin County led the way with 7.3 inches of snow reported in Eustis, with Cumberland County following closely with 6.3 inches at Portland International Jetport and 5 or more inches in South Windham, Standish, Bridgton and Gorham.

Jackman, in Somerset County, reported an accumulation of 6 inches, while Edgcomb in Lincoln County had 5 inches.

The snow was expected to continue through Monday night in those areas, with the weather alerts in effect through Tuesday morning.

Monday’s storm prompted more than 170 closures and cancellations for businesses, schools and classes and government offices.

It also prompted overnight parking bans in numerous communities, including Portland, Augusta, Kittery, Lewiston and Biddeford, to name a few.

While Bangor received a modest dusting, it too had a parking ban in effect through Tuesday morning to allow for the ongoing cleanup of snow that fell during earlier bouts of snow.

Motorists in the affected areas were advised that the new snow, combined with gusty winds, could lead to blowing snow and hazardous travel.

The weather service’s Caribou office announced Monday that Bangor has tied it’s all-time record for snow depth.

As of 7 a.m. Monday, the city’s snow depth was 53 inches, tying a record nearly four decades old (1969).

Tim Duda, a forecaster at the weather service’s Caribou office, said the snow measurement is based on how much snow is on the ground at Bangor International Airport.

“That’s the actual depth of snow that’s on the ground at this time,” he said.

Recordkeeping in Bangor began in 1926.
