The National Weather Service warned that more than 70 million people face severe weather risks on Tuesday, following deadly tornadoes that struck the Midwest. Forecasters are tracking a powerful storm system that could produce additional tornadoes, damaging winds, and large hail across a wide swath of the country.

This latest severe weather outbreak comes after a series of destructive tornadoes killed multiple people and caused extensive damage in several Midwest states. The same storm system that produced the deadly twisters is expected to intensify and move eastward, bringing dangerous conditions to new areas. Meteorologists are particularly concerned about the potential for nighttime tornadoes, which are especially deadly.

Emergency management officials are urging residents in the affected regions to review their severe weather safety plans and stay alert for warnings. The National Weather Service has issued tornado watches and severe thunderstorm warnings for parts of the Midwest and South, with the threat expected to continue through Tuesday evening.
