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.
Dallas, Oregon, located in the Willamette Valley, has experienced 15 documented tornadoes within a 25-mile radius since 1950, according to the NOAA Storm Prediction Center. The majority of these events have been weak, with 11 rated EF0 and only one reaching EF2 intensity. Notably, no tornado-related fatalities have been recorded in the area during this period, reflecting both the generally weak nature of Pacific Northwest tornadoes and the region's lower population density compared to more tornado-prone areas of the country.
Tornado activity near Dallas has varied considerably by decade. The 1990s saw the highest concentration with seven events, while the 1960s, 1970s, and 1980s each recorded only a single tornado. The 2000s and 2010s documented two and three tornadoes respectively. Unlike much of the central United States where tornado season peaks in spring and early summer, the Dallas area sees its highest activity in September, with four tornadoes occurring during that month. This pattern reflects the Pacific Northwest's distinct meteorological conditions, where autumn weather systems can occasionally produce tornadic activity.
The most significant tornado on record occurred on December 15, 2010, when an EF2 tornado carved a 5.0-mile path with a maximum width of 150 yards. This event caused $1.2 million in property damage but resulted in no fatalities or injuries. The December timing is unusual compared to national patterns but not unprecedented for western Oregon, where winter storm systems can occasionally generate tornadoes. This single event stands as the costliest, widest, and longest-track tornado in the area's recorded history.
The most recent tornado near Dallas was an EF0 event on October 29, 2018, which traveled just 0.1 miles with a maximum width of only 10 yards and caused minimal damage estimated at $200. The Enhanced Fujita scale, used to rate tornado intensity based on damage indicators, ranges from EF0 (winds 65-85 mph) to EF5 (winds over 200 mph). The predominance of EF0 and EF1 tornadoes in this region reflects the weaker atmospheric dynamics typically present in western Oregon compared to the Great Plains.
