Whilst the worst of the storms appears to have subsided, a threat remains.
The weekend storms brought tornadoes and unprecedented flooding across the central USA in the region known as "Tornado alley".
Forecasters warned that more than 2 million people lie in the path of a series of storms that could produce an outbreak of violent, large-scale tornadoes across parts of Texas and Oklahoma, along with baseball-size hail, flash flooding and hurricane-force winds.

Damaging tornados also struck near Mangum, Oklahoma, Leach, Oklahoma, and Paducah, Texas, on Monday.
While the risk of strong tornadoes is not expected to be as high as Monday, there will be a continued risk of tornadoes on a localised level.
