Officials reported an apparent tornado near Huntsville, Alabama, as storms continued to threaten the Midwest and South on Friday.
At-risk areas may incude southern Indiana, southern Ohio, most of Kentucky, central Tennessee, northeastern Mississippi and northwestern Alabama, say emergency officials.
According to CNN meteorologist Sean Morris, widespread damaging wind gusts, large hail and violent tornadoes may occur in some areas:
Storms will begin to weaken during the late evening as they move eastward toward the Appalachians. The severe weather threat will diminish overnight Friday into Saturday morning, Morris said.
The tornado outbreak that began Tuesday night left 13 dead across Kansas, Missouri, Illinois and Tennessee and battered parts of Kentucky as well. The latest death was reported in Kansas, where authorities said 53-year-old Richard Slade died Thursday from injuries suffered when a tornado struck Harveyville on Tuesday night.
