The death toll in Saturday's blizzard packing hurricane-force winds that struck northeastern United States and Canada on Saturday has risen to 15, reports said.
At least 11 deaths were reported in the US and four in Canada.
In the US, around 700,000 homes and businesses were left without power and travel came to a grinding halt as the storm dumped more than three feet of snow across the northeast.
Wind gusts of 80 miles an hour cut power lines and uprooted trees.
Connecticut, Rhode Island and Massachusetts were the worst affected by the storm, media reports said.
More than 5,000 flights from some 60 airports were cancelled on Friday and Saturday, according to FlightAware, which tracks airline delays.
The blizzard brought back memories of Hurricane Sandy that hammered the same region last year, leaving over 100 people dead in the United States.
The storm, spawned by the collision of two weather systems, reportedly affected more than 40 million people.
