A powerful Midwest storm system killed one person and injured four others when it rolled through southwestern Arkansas on Monday.

The storm system swept through Texas, Oklahoma and Arkansas, resulting in one death and injuring four people early Monday when it struck a home near Ashdown, which is about 150 miles southwest of Little Rock, reports CBS News.

Rick Fahr, a spokesman for the Arkansas Department of Emergency Management, reported that trees and power lines had toppled in other parts of the state, reports NBC News.

It also caused power outages, leaving thousands of people in the dark, reports CBS affiliate KTHV. According to Entergy Arkansas, there were 7,274 outages by late Monday morning.

In northeast Louisiana, there were reports of toppled trees, damaged roofs and one person with a minor injury in Monroe, said Ouachita Parish Sheriff's office spokesman Glenn Springfield. In addition, the News Star reported 38,000 were left without power.

The storms, which began Sunday across Oklahoma, also damaged power lines and overturned tractor-trailers along Interstate 40.

The Storm Prediction Center predicted that over 36 million people would be affected by the storm as it continued to head east, bringing damaging winds, possible tornadoes and heavy rainfall on Monday. However, forecasters say the greatest risk is along the Mississippi River from southern Illinois to northern Louisiana.

Other cities expected to be hit by the storm include Memphis and Nashville, Tennessee; Houston; Indianapolis; New Orleans; and St. Louis.

There were some reports of tornado sightings near St. Louis and in northern Louisiana by late afternoon Monday, however none have been confirmed yet.

Downed trees were reported in parts of northern Louisiana.

A fire also began at an oil well near Longview, Texas which is suspected to have been started by lightning. In the meantime, thousands of homes and businesses lost electricity in parts of North Texas.
