The Kalamazoo Tornado of 1980 struck downtown Kalamazoo, Michigan, on Tuesday, May 13, 1980. The tornado, which touched down at 4:09 pm, was rated F3 on the Fujita scale. The tornado killed 5 people and injured 79. Damage was estimated at $50,000,000, which included $1,800,000 in vehicle damage.

The Fujita scale (F-Scale; ), or Fujita–Pearson scale (FPP scale), is a scale for rating tornado intensity, based primarily on the damage tornadoes inflict on human-built structures and vegetation. The official Fujita scale category is determined by meteorologists and engineers after a ground or aerial damage survey, or both; and depending on the circumstances, ground-swirl patterns (cycloidal marks), weather radar data, witness testimonies, media reports and damage imagery, as well as photogrammetry or videogrammetry if motion picture recording is available. The Fujita scale was replaced with the Enhanced Fujita scale (EF-Scale) in the United States in February 2007. In April 2013, Canada adopted the EF-Scale over the Fujita scale along with 31 "Specific Damage Indicators" used by Environment Canada (EC) in their ratings.
