This page documents the tornadoes and tornado outbreaks of 1947, primarily in the United States. Most recorded tornadoes form in the U.S., although some events may take place internationally. Tornado statistics for older years like this often appear significantly lower than modern years due to fewer reports or confirmed tornadoes.
All documented significant tornadoes prior to 1950 in the United States were given unofficial ratings by tornado experts like Thomas P. Grazulis, which this article uses for the ratings below. Most of these records are limited to significant tornadoes; those rated F2 or higher on the Fujita scale, or which caused a fatality. Some listed events were tornado families rather than single tornadoes.[2] There are also no official tornado counts for each month, so not every month is included in this article. In subsequent years, the documentation of tornadoes became much more widespread and efficient, with the average annual tornado count being around 1,253.[3] Outside the United States, various meteorological organizations, like the European Severe Storms Laboratory rated tornadoes, which are considered official ratings.
