Bloomington, California has experienced 16 documented tornadoes within a 25-mile radius since 1950, according to the NOAA Storm Prediction Center. This relatively modest total reflects the region's location in Southern California, where tornadoes are far less common than in the central and southeastern United States. The Enhanced Fujita scale, which rates tornado intensity from EF0 (weakest) to EF5 (strongest), classifies 14 of these events as EF0, with one EF1 and one EF2 recorded.
Tornado activity in the Bloomington area has shown some variation over the decades. Only one tornado was recorded in each of the 1950s and 1960s, followed by two in both the 1970s and 1980s. Activity increased somewhat in the 1990s with three events, then peaked during the 2000s with five tornadoes. The 2010s saw two documented events, the most recent occurring on September 9, 2012.
May stands out as the most active month for tornadoes near Bloomington, accounting for five of the 16 recorded events. This aligns with broader national patterns, as spring months typically see increased tornado activity due to the collision of warm, moist air masses with cooler, drier air. The most significant tornado in the area's recorded history occurred on May 22, 2008, when an EF2 tornado carved a 2.8-mile path with a maximum width of 75 yards. This event caused $350,000 in property damage but resulted in no fatalities, making it simultaneously the costliest, widest, and longest-track tornado on record for the area.
Notably, no tornadoes within 25 miles of Bloomington have resulted in fatalities since record-keeping began in 1950. The September 2012 tornado, while the most recent, was a brief EF0 event with a maximum width of only 10 yards and no recorded path length or property damage. The predominance of EF0 events in the historical record indicates that most tornadoes affecting this region have been relatively weak, with wind speeds below 85 miles per hour.
