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.
Since 1950, the Keizer, Oregon area has experienced 19 tornadoes within a 25-mile radius, according to the NOAA Storm Prediction Center. Unlike the Great Plains where tornadoes peak in spring and early summer, this region sees its highest tornado activity in October, which has recorded 5 events. The vast majority of these tornadoes have been weak, with 13 rated EF0 on the Enhanced Fujita scale, 4 rated EF1, and only 2 reaching EF2 intensity.
Tornado activity in the area has been sporadic across the decades. The 1960s, 1970s, and 1980s each saw just a single tornado, but activity increased notably in the 1990s with 8 recorded events. The 2000s brought 3 tornadoes, followed by 4 in the 2010s, and 1 thus far in the 2020s. This pattern reflects the relatively infrequent but persistent nature of tornado development in the Pacific Northwest's unique meteorological environment.
The costliest tornado on record struck on December 9, 1993, rated F2 with maximum winds capable of significant damage. This storm carved a 6.0-mile path with a maximum width of 120 yards and caused $2.75 million in property damage. Nearly two decades later, on December 15, 2010, an EF2 tornado became the widest on record at 150 yards, traveling 5.0 miles and causing $1.2 million in damage. Both December events illustrate how tornadoes in this region can occur outside the traditional spring severe weather season common to other parts of the country.
Remarkably, none of the tornadoes recorded near Keizer have resulted in fatalities. The most recent event occurred on October 24, 2022, when an EF0 tornado with a maximum width of just 17 yards caused $25,000 in property damage. While tornadoes remain relatively rare in western Oregon compared to the central United States, the historical record demonstrates that residents should maintain awareness of severe weather potential, particularly during the autumn months.
