At least 21 dead after large tornado strikes Western Mississippi

At least 21 people are dead as western Mississippi deals with severe tornado damage. The massive storm system, affecting up to 30 million people, stretched from the lower Mississippi valley to the lower Ohio valley.

The storms knocked out the power for more than 100,000 people across several states. They also produced a flash flooding threat — as torrential rainfall is expected across a large swath of the US stretching from Oklahoma to West Virginia.

Nearly 19 million people were under flood watches across at least eight states in the mid-south and central regions.
