PITTSFIELD, Mass. – A storm system is bringing wintry weather to the Northeast, dumping up to 18 inches of snow in parts of upstate New York.

Schools in central New York and western Massachusetts called off classes Monday or delayed their start by two hours.

The National Weather Service says the storm that started over the weekend dropped up to 18 inches near Binghamton and Syracuse in New York.

The town of Savoy, Massachusetts, got more than a foot of snow while Lenox got 11 inches on Sunday, according unofficial National Weather Service figures. Some utility customers also lost electricity after wind gusts topping 40 mph brought down power lines.

Northwest Connecticut was also hit hard, with the towns of Milton and Norfolk getting a foot or more of snow. There were also scattered power outages.

In New Hampshire, the snow caused car crashes and spin-outs.

WMUR-TV reported that crews responded to accidents on major highways, including I-93, I-89, Route 101 and the Spaulding Turnpike. Route 4 in Durham was closed at the Lee town line, and traffic was snarled at I-93 south in Bow.

New England ski areas, meanwhile, were rejoicing, with the traditional start to the winter sports season coming up this week.

More than a dozen New Hampshire ski areas announced their tentative opening days, starting with Loon Mountain Resort, which planned to open Wednesday.

In addition to Loon, the earliest openings were expected at Bretton Woods, which set Thursday as its target, and four areas that planned to open on Friday: Cranmore Mountain Resort, Mount Sunapee Resort, Cannon Mountain and Waterville Valley Resort. The dates are tentative and weather-dependent.

The Mount Washington Observatory recorded 1.9 inches of snowfall.

The storm was expected to wind down later Monday.
