[Rockhounds] Watch Out: Tornado Alley Is Migrating Eastward

[Kreigh Tomaszewski]

The nation's "Tornado Alley" has shifted and tornadoes are increasing in
colder times of the year, a recently published study found.

The Deep South "Alley": Since the mid-1980s, tornadoes have been most
numerous in the Deep South, including Mississippi, Alabama, Louisiana and
Tennessee, according to a recent study

by
Timothy Coleman, Richard Thompson and former The Weather Channel severe
weather expert Greg Forbes.

Published in the April 2024 issue of the Journal of Applied Meteorology and
Climatology, the study examined tornadoes rated F/EF1 or stronger over two
separate, 35-year periods (1951-1985 and 1986-2020) to look for changes in
where these tornadoes formed. F/EF0 tornadoes were excluded to filter out
the much greater number of these weakest tornadoes detected in recent years
due to improved technology and more extensive National Weather Service
damage surveys.

As the map below shows, a corridor of increased tornadoes extended from the
lower Ohio Valley to the Deep South and westward to Oklahoma.
