After battering Bermuda with heavy rain, strong winds and massive waves, Hurricane Fiona is taking aim at northeastern Canada as forecasters warn of one of the strongest storms on record for the region.

A hurricane warning is in effect for Nova Scotia, Prince Edward Island, The Magdalen Islands and the coast of Newfoundland as the U.S. National Hurricane Center forecasts hurricane conditions may begin in Atlantic Canada late Friday.

Fiona weakened slightly to a Category 3 hurricane Friday.. The hurricane center still expects the storm to be a “large and powerful post-tropical cyclone with hurricane-force winds,” as it rips through northeastern Canada, threatening significant coastal flooding and 3 to 6 inches of rain with local maximums of up to 10 inches in some areas.

Parts of Atlantic Canada may see “life-threatening flooding, damaging hurricane-force wind gusts and dangerous storm surges,” AccuWeather said.

Widespread power outages are also expected, said Dave Pickles, chief operating officer of the utility company Nova Scotia Power.

Fiona may be ‘historic storm’ in eastern Canada

The Canadian Hurricane Centre called Fiona a “historic storm for eastern Canada” and a “potential landmark weather event.”

Hurricanes are relatively rare in Canada, where many storms weaken as they reach colder waters. As a result, AccuWeather meteorologists said Fiona “will likely be the most intense storm on record” in terms of the magnitude of the wind gusts.
