This overview was written April 23, 2026. The tornado counts and notable-event figures elsewhere on this page reflect the latest data and may differ from this summary.
Lehi, Utah, has experienced 17 documented tornadoes within a 25-mile radius since 1950, according to the NOAA Storm Prediction Center. This relatively modest count reflects the intermountain West's generally lower tornado frequency compared to the Great Plains, though the city is not immune to these rotating storms. The majority of recorded events have been weak, with 10 rated EF0 and 6 rated EF1 on the Enhanced Fujita scale, which measures tornado intensity from EF0 (weakest) to EF5 (strongest). Only one tornado reached EF2 strength during this period.
Tornado activity near Lehi peaked during the 1980s and 1990s, with five tornadoes recorded in each decade. The 1960s and 1970s each saw two events, while the 2000s recorded two and the 2010s only one. September has been the most active month historically, accounting for four tornadoes, an unusual pattern since tornadoes nationally peak in spring and early summer. This late-season activity may reflect localized atmospheric conditions during the transition from summer to fall.
The most significant tornado on record occurred on August 11, 1999, when an F2-strength storm resulted in one fatality and caused $170 in property damage along a 4.3-mile path with a maximum width of 150 yards. This remains the only deadly tornado documented in the area since 1950. The costliest event was an F1 tornado on January 10, 1989, which caused $27,500 in damage despite traveling only 0.2 miles with a narrow 23-yard width. The widest tornado, an F1 on December 2, 1970, reached 300 yards across during its one-mile path, while the longest-track tornado traveled 10.0 miles on July 26, 1991.
The most recent tornado near Lehi touched down on September 7, 2013, as an EF0 with a brief 0.1-mile path and minimal width of just 3 yards. It caused $10,000 in property damage with no injuries. While tornadoes remain relatively rare in this region, the historical record demonstrates that they can occur across multiple seasons and occasionally produce significant impacts.
