Tracy, California, located in the Central Valley east of the San Francisco Bay Area, has experienced 20 documented tornadoes within a 25-mile radius since 1950, according to the NOAA Storm Prediction Center. While tornadoes are relatively uncommon in California compared to the central United States, the state does see occasional tornado activity, particularly in the Central Valley during the spring months when atmospheric conditions align to produce severe thunderstorms.
The majority of tornadoes recorded near Tracy have been weak, with 16 rated EF0 on the Enhanced Fujita scale, which measures tornado intensity from EF0 (weakest) to EF5 (strongest). Three tornadoes reached EF1 intensity, and only one achieved EF2 strength. Notably, none of the tornadoes on record in this area have resulted in fatalities.

April has been the most active month for tornado activity near Tracy, accounting for 10 of the 20 recorded events. This seasonal pattern aligns with springtime weather conditions when cold fronts moving through California can interact with warmer, moist air to generate rotating thunderstorms. The longest-tracked tornado in the area was an EF1 that traveled 1.6 miles on January 23, 2010, demonstrating that tornado activity can occur outside the typical spring peak, though such winter events are less common.
Tornado frequency near Tracy has varied by decade, with the 1990s seeing the most activity at five events, followed by four tornadoes in the 2000s.

While tornadoes remain a relatively infrequent hazard in the Tracy area compared to many other regions of the United States, the historical record demonstrates that residents should maintain awareness of severe weather potential, particularly during the spring months.
