Several people have died in a winter storm that hit a wide swath of the US, causing thousands of flights to be cancelled or delayed due to conditions.
The storm, which caused chaos from Texas to the tip of Maine over the weekend, snarled roadways, knocked out power, and buried major cities under a thick blanket of snow.
At least a dozen people have been killed in several US states. Some areas in the northeast saw over 20 inches (50.8 cm) of snow in the last 24 hours, according to the National Weather Service (NWS), and Canadian officials said the storm has seriously disrupted southern Ontario.
Forecasters warn another "significant winter storm" could hit the eastern US again this weekend.
More than 200,000 people had lost power in Tennessee as of Monday afternoon. The city experienced a deep freeze that plunged residents into cold and darkness.
