Tornadoes of 1927

Grazulis's record has 157 significant tornadoes in the United States in 1927, which killed 543 people and injured 3,625. 18 were rated F4 or above, 2 of them F5. Before 1950 the record is Thomas P. Grazulis’s list of significant tornadoes: those rated F2 or stronger, and weaker ones that killed somebody.

1926 1928

The rating scale

Tracks are drawn in the color of the rating. Grazulis rated these tornadoes on the Fujita scale decades after the fact, from written accounts of the damage. The scale rates the damage rather than measuring the wind: the speeds are what that damage is taken to imply.

  1. F040 to 72 mph

    Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.

  2. F173 to 112 mph

    Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.

  3. F2113 to 157 mph

    Considerable damage. Roofs torn off well-built houses, frame homes shifted on their foundations, mobile homes destroyed, large trees snapped or uprooted, cars lifted off the ground.

  4. F3158 to 206 mph

    Severe damage. Whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, trees debarked, heavy cars lifted and thrown.

  5. F4207 to 260 mph

    Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.

  6. F5261 to 318 mph

    Incredible damage. Strong frame houses swept off their foundations, car-sized missiles thrown more than 100 meters, steel-reinforced concrete badly damaged, high-rise buildings deformed.

  7. Unrated

    Grazulis gave no rating: the surviving account records a tornado without enough about the damage to rate it. Almost all of these are before 1880.

About the record before 1950

Significant tornadoes only
Grazulis listed tornadoes rated F2 or stronger, and weaker ones that killed somebody. Most tornadoes are weaker than F2, so the list holds a fraction of the tornadoes that happened.
The early years are thin
A tornado is on record only where somebody saw it and wrote it down. The count rises through the 1800s with settlement and newspapers, not with the weather.
Rated from accounts
Grazulis rated each tornado decades later from newspaper reports, Weather Bureau records and local histories, not from a damage survey.
The tracks are reconstructed
Tornado Archive drew each path through the places Grazulis names, most often as a straight line from the first to the last. A track can miss a town it hit, and a tornado with one named place is a point. The counties are today’s.
A separate record
SPC’s database, from 1950, counts every confirmed tornado of any strength. The two are kept apart on every page and never added together.

What this means

Ratings are Grazulis's, read from written accounts of the damage; the rating scale is above. About the record before 1950 says what it holds and what it leaves out.
