At least five people have died after severe thunderstorms swept through the central United States, spawning a tornado that flattened homes as well as gale force winds and widespread flooding stretching from the Upper Midwest to Appalachia.

The weather system that stretched from Texas to the Canadian Maritime provinces had prompted several emergency declarations even before the storms arrived.

In south-western Michigan, the body of a man was found floating in floodwaters in Kalamazoo.

Officials said the death did not appear to be suspicious and that authorities were trying to determine the man’s identity and cause of death. Kalamazoo was hard hit by flooding from last week’s heavy rains and melting snow.
