DW News (April 2, 2023) – At least 21 people have been killed and many more injured as storms batter the South and Midwest. Authorities in Arkansas have declared an emergency after multiple tornadoes tore through the state.
Tornadoes develop from severe thunderstorms in warm, moist, unstable air along and ahead of cold fronts. Such thunderstorms also may generate large hail and damaging winds. When intense springtime storm systems produce large, persistent areas that support tornado development, major outbreaks can occur.
