A widespread outbreak of severe weather is threatening a large portion of the U.S., extending from the Gulf Coast to the Tennessee Valley.
A line of severe thunderstorms is progressing eastward across this area and will continue to press eastward into Tuesday.
“The storms are bringing the threat of damaging winds, large hail, flooding downpours and even an isolated tornado,” AccuWeather.com Meteorologist Andy Mussoline said.
Wind gusts with these storms can be strong enough to bring down trees and power lines and may result in disruptions to electricity services.
The Associated Press reports that one person is dead and four were injured in Arkansas after storms swept across the state. Damage to buildings and power outages have also been reported in several towns in Louisiana.
