North America's East Coast is shivering in a record-breaking freeze just a day after a deadly "bomb cyclone" dumped snow as far south as Florida.
According to the National Weather Service, in parts of US and Canada, temperatures are expected to fall below 29C.
In Canada, high winds have knocked out power for tens of thousands of residents in Nova Scotia.
Giant waves caused by the storm saw freezing floodwaters inundate parts of the New England coast.
The extreme weather has so far been linked to up to 19 deaths in the US and two more in Canada, according to reports.
