Tornadoes of 1965

This page documents the tornadoes and tornado outbreaks of 1965, primarily in the United States. Most 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.

Events
1965 picked up where 1964 left off, becoming the most active year on record at the time. A total of 31 violent (F4 and F5) tornadoes also touched down, which was also a record, with 17 of the F4 tornadoes occurring during the 1965 Palm Sunday tornado outbreak.

April 10–12
An extremely destructive and deadly outbreak of 55 tornadoes caused major damage from the Southern Plains to the Midwest. The main outbreak was the Palm Sunday tornado outbreak, which started in the afternoon of April 11 and continued through the overnight hours of April 12. The second-biggest tornado outbreak on record at the time, this deadly series of 48 twisters inflicted a swath of destruction from Cedar County, Iowa, to Cuyahoga County, Ohio, and a swath 450 mi from Kent County, Michigan, to Montgomery County, Indiana. The outbreak lasted 16 hours and 35 minutes and is among the most intense outbreaks, in terms of number, strength, width, path, and length of tornadoes, ever recorded, including at least four "double/twin funnel" tornadoes. In addition, 17 tornadoes were rated F4, the second-largest number of violent twisters in one outbreak, after the 1974 Super Outbreak. At one point, all nine counties in the northern Indiana office's jurisdiction were under a tornado warning, marking the first occurrence of a "blanket tornado warning" in the U.S. Weather Bureau's history. However, as was the case in many other areas heavily affected, the outbreak began on Palm Sunday, an important holy day for most Christians, and many people were attending church services, which may explain why some tornado warnings were never received. As a result, 266 people were killed and 3,662 injured with 1,795 of them in Indiana alone. It was also the deadliest tornado outbreak in Indiana history, with 137 people killed.
