CONCORD, N.H. (AP) — A fast-moving storm dumped about a foot of snow in parts of northern New England on Tuesday.

Heavy snow fell Tuesday afternoon and picked up in intensity as the evening commute began. In New Hampshire, 12 inches of snow were reported Tuesday night in New Boston, 11 were reported in Goffstown and Merrimack and there were 10 in Nashua and other places.

Nashua, one of New Hampshire’s biggest cities, imposed a snow emergency, banning parking on streets until 5 a.m. Wednesday.

In Maine, nearly 10 inches of snow fell in Kennebunk and close to 9 fell in Portland, the National Weather Service said. In Vermont, 5 fell in Mount Holly and 5.5 fell in Rochester.

There were no immediate reports of any major traffic messes caused by the weather.

Fire officials in Plaistow, N.H., investigated three carbon monoxide poisoning deaths at a home but said the cause likely was a problem with a furnace and wouldn’t link it to the storm.

Winter storm warnings were in effect for southern and eastern New Hampshire and coastal and interior Maine. A winter advisory was in effect for Vermont.

It’s already been a snowy winter in New Hampshire. The state got 19.9 inches of snow in December, about 5 inches more than normal, the National Weather Service said. In January, 14.4 inches fell, below the 30-year normal of 18.1 inches. February more than made up the decrease: 20.3 inches of snow fell before Tuesday’s storm, compared to a 30-year normal of 12.3 inches for the month.

And in Maine, National Weather Service meteorologist Chris Legro said Portland had nearly 70 inches ”“ more than 24 inches more than normal ”“ before the latest batch of snow arrived Tuesday.

Police in New Hampshire reduced the speed limit on all highways to 45 mph.

Many New Hampshire schools canceled classes for the day or planned early dismissals; they are not on break this week like Maine schools. But there were only a few flight delays and cancellations at Manchester-Boston Regional Airport.
