(CNN) – A ‘Tornado Tuesday’ of severe storms is expected to deliver the potential for a monstrous trio of tornadoes, damaging winds, and hail to millions of people across parts of the Southeast and Mississippi Valley beginning Tuesday afternoon, forecasters are warning.More than 40 million people from southeastern Texas eastward to Georgia, and northward to central Indiana and Illinois are under a threat of severe weather Tuesday, according to the Storm Prediction Center.The largest potential for the most severe weather is for about 1 million people in parts of central Mississippi, including Jackson, as well as parts of east-central Louisiana.
In those areas, the threat for severe weather, including large hail and possible tornadoes, is a Level 4 of 5, with 5 being the highest, according to prediction the center.The Level 4, or moderate threat, is rare for this time of year for that region, which usually sees tornadoes during the spring and summer months.“Severe thunderstorms capable of producing tornadoes, very large hail, and a few severe wind gusts are expected this afternoon into the overnight period across parts of the lower to mid-Mississippi Valley and parts of the Southeast,” the prediction center said.
