Lennox, California, situated in the Los Angeles Basin, has experienced 40 documented tornadoes within a 25-mile radius since 1950, according to NOAA Storm Prediction Center records. Unlike the Great Plains where tornadoes typically peak in spring and early summer, the Lennox area shows an unusual seasonal pattern, with January recording the highest number of events at 8 tornadoes. This winter peak reflects the influence of Pacific storm systems and atmospheric dynamics unique to coastal Southern California.
The historical record shows considerable variation across decades. Tornado activity peaked during the 1980s with 10 recorded events, followed by 9 in the 1990s. Activity declined notably in the 2000s and 2010s, with only 3 and 2 tornadoes respectively, before increasing again to 5 events in the 2020s. The vast majority of these tornadoes have been relatively weak, with 20 rated EF0 on the Enhanced Fujita scale, which measures tornado intensity based on damage. An additional 15 tornadoes reached EF1 intensity, while only 5 achieved EF2 status.
The costliest tornado on record occurred on March 1, 1983, when an F2-rated tornado caused $27,500,000 in property damage along a 3.5-mile path with a maximum width of 100 yards. The widest tornado struck on November 9, 1982, reaching 1,300 yards across and traveling 10 miles while causing $2,750,000 in damage. The longest-track tornado occurred on March 17, 1977, when an F1 tornado traveled 10.9 miles with a narrow 10-yard width, also resulting in $2,750,000 in damage. Notably, none of the tornadoes in this area's recorded history have resulted in fatalities.
The most recent tornado touched down on March 13, 2025, as an EF0 event that traveled one mile with an 80-yard maximum width and caused no reported damage or injuries. This continuing activity, though generally producing weaker tornadoes compared to other regions of the United States, demonstrates that the Lennox area remains susceptible to tornado formation under the right atmospheric conditions.
