Tornadoes devastate the Midwest

Millions of residents from Tennessee to Minnesota remain under severe weather threats as a massive storm system moves through the region.

In Olmsted County, Minnesota, sheriff's officials described 'multiple levels' of destruction, with emergency crews working to clear debris and restore power.

The National Weather Service warned that the risk of funnel clouds and high winds will persist through the weekend.

Despite the extensive property damage, early warnings and community preparedness are being credited with preventing loss of life.
