In Missouri state, Governor Jay Nixon has declared a state of emergency because of widespread flooding.

"More than 1,400 power outages have been reported as of Thursday morning, and weather-related debris forced numerous road closures in the affected counties."

MEMA also confirmed at least 40 injuries in the state.
