A fast-moving snowstorm is expected to sweep across northern and central Maine on Sunday, according to the National Weather Service in Caribou.

The storm is forecast to arrive around midday and wrap up by midnight, bringing 1 to 4 inches of wet snow to areas north of Bangor.

Downeast, south winds may gust between 35 and 45 mph, creating a risk of power outages.

The weather service is also monitoring a potential storm on Tuesday that could bring significant snowfall south of Houlton — but forecasters said it’s still too early to determine the exact track, and the system could also move out to sea.

Beginning next year, a new outdoor education initiative will allow every 8th grade student in the St. John Valley to participate in a three-night canoe expedition on the Allagash Wilderness Waterway.

Dan Dinsmore, executive director of the Allagash Wilderness Waterway Foundation, said the annual Youth on the Allagash program will cost roughly $75,000 and will be funded by his organization.

“The effort here is to not do this once, but to do this in a sustained way and bake the Youth on the Allagash into the school calendar for all three of these schools,” he said.

The Allagash, which is part of the National Wild and Scenic River system, extends 92 miles between Aroostook and Piscataquis counties.

Dinsmore said the idea is to give students a transformational outdoor experience right in their backyard.

“We’re trying to raise that next generations of stewards who will just take this sort of, you know, hometown pride in this incredible wild river,” he said.

Dinsmore said the trip will be run by Chewonki guides and will also give students a chance to learn about careers in Maine’s North Woods.
