A major storm system is bringing significant risks of severe weather across much of the United States this week. Tornado risks and powerful winds are threatening over two-thirds of the country, with alerts issued for strong storms expected late on Fat Tuesday. Residents are bracing for a variety of extreme weather conditions, including high winds, flooding, and potential tornadoes in areas from the Deep South to the Mid Atlantic. Multiple states have been placed under weather alerts as forecasters predict damaging storms starting Tuesday morning and continuing into the night, prompting a First Alert Weather Day. As the storm system moves, blizzard conditions are expected in the Heartland while the South prepares for strong to severe storms. Authorities are urging residents to stay informed and prepared for rapidly changing weather conditions.
