Deadly cold weather has brought what meteorologists call a “once-in-a-generation” deep freeze to large areas of the US.
Forecasters say temperatures over the next few days will go as low as -30C in the Midwest, with wind chill making it feel even colder.
At least five people are reported to have been killed across several states as a direct result of the cold weather.
Snow is expected to fall as far south as Alabama and Georgia.
As much as 24in (60cm) of snow is forecast in the state of Wisconsin, and 6in in Illinois.
Snow is expected to fall throughout Wednesday, from the Great Lakes region into New England.
