Frederickson, Washington has experienced 12 documented tornadoes within a 25-mile radius since 1950, according to NOAA Storm Prediction Center records. All of these events have been relatively weak, classified as either EF0 or EF1 on the Enhanced Fujita scale, which measures tornado intensity based on damage. The area has seen no tornado-related fatalities on record, reflecting both the lower intensity of Pacific Northwest tornadoes and the region's generally lower tornado frequency compared to the central United States.
Tornado activity in the Frederickson area has been distributed unevenly across the decades. The 1970s and 1990s each recorded two tornadoes, while only one occurred during the 1980s. Activity increased somewhat in recent decades, with four tornadoes documented in the 2000s and three in the 2010s. Of the 12 total events, five were rated EF0—the weakest category, typically causing minor damage to trees and signs—while seven reached EF1 intensity, capable of damaging roofs and overturning mobile homes.
June has been the most active month for tornadoes near Frederickson, accounting for three events. This aligns with broader patterns in the Pacific Northwest, where late spring and early summer can produce the atmospheric instability necessary for tornado formation when cold fronts interact with warmer, moist air masses. The costliest tornado on record struck on September 6, 2009, an EF1 event that caused $180,000 in property damage while traveling 9.6 miles with a maximum width of 170 yards. This same tornado also holds the record as the longest-tracked in the area.
The widest tornado near Frederickson occurred on June 28, 2001, reaching 400 yards across during its 2.3-mile path, though it caused no reported property damage. The most recent tornado touched down on January 18, 2015, an EF1 that traveled 4.1 miles with a maximum width of 175 yards, also resulting in no damage or injuries. Winter tornadoes are uncommon but not unprecedented in western Washington, where Pacific storm systems occasionally produce the conditions necessary for weak tornado development.
