Pasco, Washington has experienced six tornadoes within a 25-mile radius since record-keeping began in 1950, according to the NOAA Storm Prediction Center. This relatively low frequency reflects the Pacific Northwest's generally unfavorable conditions for tornadic development, as the region lacks the combination of warm, moist air masses and strong wind shear that characterize more tornado-prone areas of the United States.
The majority of recorded tornadoes near Pasco have been weak, with four rated EF0 on the Enhanced Fujita scale, which measures tornado intensity based on damage. One tornado reached EF1 intensity, and one attained EF2 status, representing the strongest on record for the area. Notably, none of these tornadoes resulted in fatalities. The costliest event occurred on April 23, 1983, when an F1 tornado caused $27,500 in property damage along a three-mile path with a maximum width of 100 yards.
Tornado activity near Pasco has been sporadic across the decades. Three tornadoes occurred during the 1950s, including a remarkable F0 event on April 24, 1958, that traveled 45 miles—the longest path length recorded in the area—despite being only 17 yards wide at its maximum and causing just $25 in damage. Single tornadoes were documented in the 1980s, 2010s, and 2020s respectively. April has been the most active month with two recorded events, though tornadoes have also occurred in March and May.
The most recent tornado touched down on March 31, 2020, as an EF0 with a brief 0.1-mile path and 20-yard maximum width, causing no damage or injuries. The widest tornado on record, at 100 yards, occurred on May 22, 2016, also rated EF0, with minimal property damage of $20,000. These events underscore that while tornadoes can occur in the Pasco area, they remain infrequent and typically weak compared to tornadoes in other regions of the country.
