At least 36 people have died across seven states as powerful storm systems swept through the Midwest and South. The storms have left hundreds of thousands of customers without power, injured dozens in Arkansas and caused fatalities linked to wildfires in Oklahoma.

Twelve fatalities were reported in Missouri – the most of any state struck by the storm – from scattered twisters, thunderstorms and gigantic hail that wreaked havoc on dozens of communities.

A dangerous, multiday severe weather outbreak is set to bring tornadoes, flash flooding and damaging winds to the Midwest, the South and the East Coast.
