Over the past 24 hours, more than 40 reported tornadoes have swept across eight states in the Midwest and South — and the dangerous severe weather threat continues.

The eight states with reported tornadoes in the past day are Alabama, Missouri, Arkansas, Mississippi, Louisiana, Illinois, Indiana and Tennessee.

Overall, there have been more than 500 reports of severe weather since late Friday, from the Midwest into the South, including not only tornadoes, but damaging wind gusts and large hail.

Across the South, Tornado watches remain in effect in portions of Mississippi, Alabama, Louisiana, Tennessee and Georgia as a line of powerful storms continues to sweep east.

A tornado watch designated a “Particularly Dangerous Situation” remains in effect for much of Alabama and portions of Mississippi and Louisiana until 8 p.m. CT. The worst of the tornado threat will be over after this.

A tornado watch designated a “Particularly Dangerous Situation” on March 15, 2025.

From eastern Tennessee, including Knoxville, into northwestern Georgia, a tornado watch remains in effect until 1 a.m. ET. Additional watches could be posted in the coming hours for points east, across George and into the Florida Panhandle.

There is also the threat of additional severe thunderstorms bringing potentially damaging wind gusts and large hail. Any stronger, slow-moving thunderstorms could also bring torrential rain and frequent lightning.

Dangerous flash flooding is also a concern. Flash flood warnings are in effect from southern Mississippi through central Tennessee.
