Hydro-Québec has been called to help local authorities in the United States this weekend as a winter storm wallops the East Coast. 

The company has sent more than 200 workers to Long Island, N.Y.

Marc-Antoine Pouliot, the spokesman for Hydro-Québec, said the organization is able to lend a hand because Quebec will be spared from the storm.

He also said Quebec workers could stay longer than scheduled if American authorities still need their help.

The blizzard is set to blanket some regions in as much as 75 centimetres of snow.

Flights cancelled across Canada

Over 50 flights have been postponed or cancelled at Montreal-Pierre Elliott Trudeau Airport for the weekend and even into Monday.

The snowstorm also forced thousands of flight cancellations across the rest of Canada and in the U.S.

Travellers heading to or departing from Boston, Philadelphia and New York City should expect delays or cancellations. 

Cities across the northeastern U.S. are under blizzard watches and Virginia, Maryland and North Carolina have declared states of emergency.
