Break out the hand-held fans and locate those sun visors. Most of Canada is poised for sweltering, hotter-than-usual weather this summer, a long-term forecast predicts.

Above-average temperatures are expected to blanket much of the nation between June and August. Projections indicate unusually warm weather will bake communities as far east as Nova Scotia, stretch from Ontario to the Prairies and envelop Nunavut as well.

But some reprieve is expected for Canadians living in parts of British Columbia, the Yukon and Quebec where normal temperatures are predicted, according to the AccuWeather forecast released this week.

In fact, the U.S. forecasting firm is calling for below-normal temperatures off the West Coast, which should prompt some cooler weather over most of B.C.

On the other hand, the southern Prairies are expected to be particularly hard-hit by lower-than-average precipitation and unusually warm weather. The projection comes as just Slave Lake, Alta. marks one year since a spate of wildfires, exacerbated by hot and dry weather, devastated much of the town.

However, if predictions from AccuWeather's senior meteorologist Brett Anderson hold true, wet and stormy weather is in the cards for parts of Ontario in Quebec.

"I believe there will be a greater number of thunderstorms over northeastern Ontario and Quebec," he wrote in a blog post dedicated to Canada's summer forecast.

Anderson is also calling for more clouds, fog and humidity over Newfoundland, a prediction that may not be a revelation for most East Coasters.

Perhaps more disquieting though is that the forecast anticipates one or two tropical storms hitting eastern Nova Scotia and southern Newfoundland in August.
