Dustin Kelley drives a bulldozer atop a three-story Gorham Sand and Gravel snow dump on Commercial Street in Portland in Wednesday. Steve Stuart, in the company office, estimated the pile at something like 100,000 square yards of snow.

Another 1 to 6 inches of snow will blanket Maine on Wednesday, adding a fresh coat to Tuesday’s massive dump that has forced a second round of school and government closures.

Yesterday’s storm — the state’s third nor’easter in two weeksclobbered the state with more than 20 inches of snow in some places, leaving as much as 23 inches of snow in some southern areas, according to the National Weather Service.

As of 9 a.m. Wednesday, it also had resulted in more than 17,000 electricity customers losing power.

More than 11,000 Emera Maine customers spread throughout the company’s service area lacked electricity, with the biggest clusters of outages along the coast. More than 6,000 Central Maine Power customers also had lost power, with Oxford and Penobscot counties each having more than a 1,000 CMP customers without electricity.

Wednesday’s forecast is less severe. Light snow will fall for most of Wednesday, winding down along the coast in the afternoon and in the evening after dark, forecasters said.

Higher amounts will fall as yesterday’s fading storm moves north, with about 1 to 3 inches predicted in Greater Portland, 3 to 5 inches in Greater Bangor, and 4 to 6 inches north of Houlton, said Chris Norcross, a weather service forecaster in Caribou.

In the far north along the Canadian border, where less than 2 inches of snow fell Tuesday, the precipitation will continue into Thursday morning, leaving up to 6 inches on the ground, he said.

Schools across Maine — including Bangor — were closed Wednesday, some of them for the second day in a row, after a howling nor’easter blew through the state and dropped over a foot and a half of snow Tuesday.

Most local government buildings and a handful of courthouses have delayed openings, if they haven’t closed for the day.

Accumulation totals from Tuesday’s storm were still rolling in Wednesday morning, but by 7:30 a.m., some parts of Maine had already clocked in more than 23.5 inches.

As of 8 a.m., Greater Bangor already had more than 18 inches of snow, with some local areas reporting more than 20 inches, according to the weather service.

Added to the existing snow that still on the ground from last week’s nor’easter, the snow depth in Bangor reached 26 inches around 5 a.m., the deepest since Jan. 12, according to the weather service.

A similar range fell across the interior and Down East coast, Norcross said.

Towns in Maine’s farth southwest corner saw some of the highest totals as of early Wednesday, such as West Newfield and Limerick, which had 23.5 inches at 5:45 a.m. Greater Portland had an average range of 15 inches around that time.

Light winds will accompany Wednesday’s snowfall — unlike the harsh gusts that blew through during the Tuesday afternoon commute and cast the state in a blinding whiteout.

While plows were still clearing the roads Wednesday morning, conditions are not expected to be as hazardous as yesterday.
