February Tornadoes


There have been over 50 documented February tornadoes within the state of Oklahoma between 1950 and the present.

Prior to the Lone Grove tornado, there have been two other deadly tornadoes in February in Oklahoma since 1950, both occurring on February 22, 1975 in southwestern Oklahoma. On that day, one tornado struck Altus, killing two people, and another tornado killed one person near Mountain Park. These were two of six tornadoes that struck between midnight and 3 am in Oklahoma.

Prior to the Lone Grove tornado, rated EF-4, the strongest tornadoes to have occurred within Oklahoma in February since 1950 are two F3 tornadoes both that struck on February 17, 1961. One F3 tornado occurred in eastern Oklahoma county from near Spencer to northeast of Luther, and the other F3 tornado was part of a tornadic storm that moved from near Stratford to Konawa, Wewoka and to south of Shulter.

A total of 6 confirmed tornadoes from the February 10, 2009 event ties February 2009 with February 1975 for the most tornadoes to have occurred in Oklahoma during the month of February since official records began in 1950.

The 8 confirmed deaths associated with the Lone Grove, OK tornado ties it with the Morris tornado as the seventh deadliest tornado since 1950 in Oklahoma. This F3 tornado killed 8 people in the town of Morris, OK on April 26, 1984.

Prior to Tuesday, February 10, 2009, the last February tornado in Oklahoma occurred on February 25, 2000 in Tulsa.
