(CNN) - From Missouri to New York, Michigan to Florida, forecasters urged millions of Americans to keep an eye on the weather Tuesday, warning of tornadoes, high winds and hail spawned by the storm system that's killed 31 people in the last two days.
Roughly 70 million people are being warned of a slight to moderate risk of severe weather in the eastern half of the United States, according to the National Weather Service. That was a slight downgrade from an estimated 75 million people earlier in the day.
Mississippi and Alabama - where tornadoes Monday caused widespread destruction and several deaths - were again in the bull's-eye for the worst of Tuesday's forecast.
