Smoke from wildfires burning in Canada drifted over parts of northern New Hampshire over the holiday weekend, but weather experts don't anticipate any long-lasting effects on the state.

Fires have been burning in Quebec, some 200 miles northwest of Montreal and in Ontario, about 400 miles north of Toronto. The Canadian Broadcasting Corp. reported the fires had forced the evacuation of First Nations communities in each province.

“We had a cold front come through and the winds shifted to northwest and came to our region.” said Mike Kistner, a meteorologist with the National Weather Service forecast office in Gray, Maine. “Basically the noticable effect was the smoke across the region especially in the mountain areas of northern New Hampshire and Maine.”

The smoke was driven over New England by a shifting cold front that brought northwesterly winds to the region. The first observation of the smoke was reported Sunday in a regular report made from the Mt. Washington observatory. Weather watchers noted seeing a smoke cloud about 1,000 feet above the summit, which is 6,288 feet above sea level.

Kistner said the smoke will not have any effect on the weather, but some northern residents could smell smoke.

“What is more to worry about is air quality when you have smoke in the area when we already have all the pollen in the air,” Kitsner said.

Rain was expected to quench the Ontario fires, while firefighters from Alberta, in western Canada, were flown in to fight the fires in Quebec, the CBC said.

“We won't see much more of it,” Kitsner said.
