Additional notes
The damage in this photo is
consistent with a low-end
EF4
tornado (this tornado was rated F4 using the old Fujita Scale). It generally takes winds of
165 to 185 mph to cause all exterior walls of well-built homes to
collapse, and for trees to be debarked with only the stubs of the
largest branches remaining. This violent tornado resulted in 4
fatalities and 65 injuries.

Tornado Warning
Safety Note: When a basement is unavailable, it is important to
move to a small center room on the lowest floor without windows.
As shown here, tornadoes up to EF-3 and low-end EF-4 strength will
often leave small interior rooms of well-built homes standing.
This tornado struck in the middle of the night when most people were
asleep. Though this tornado was warned for well in advance and
storm sirens were sounding, many slept through the warning or did not
hear the sirens. The National Weather Service encourages all homes
and businesses to have a NOAA
Weather Radio on hand, which will sound a loud alert when a
warning is issued for your county. It is also important to have a
tornado safety plan in place before a tornado strikes. Even if you
are woke in advance of a tornado, you may be frightened and/or groggy
which will make it difficult to think clearly and take yourself to safety.
