Mississippi, Alabama, Tennessee, Arkansas, western Georgia and northern Louisiana. Nocturnal tornadoes, rain-wrapped storms, and heavy tree cover make Dixie Alley the deadliest US tornado zone — more per-tornado fatalities than the traditional alley.
The lesser-known Ohio Valley zone: Indiana, Illinois, Ohio, Kentucky. Peaks slightly later than Tornado Alley (May-June) and has produced some of the deadliest single tornadoes ever, including the 1925 Tri-State Tornado.
