Corona sits at the western edge of Riverside County, where the Santa Ana River canyon divides the Santa Ana Mountains from the Chino Hills. Tornadoes here have little in common with the Plains variety: they have tended to arrive with cool-season Pacific storms, spinning up as winter low-pressure systems push across Southern California. An F1 touched down on March 17, 1977, another F1 followed on January 31, 1979, and the winter of 1993 produced an F1 on January 14 along with F0s on January 18 and February 8. An F1 on November 11, 1997 fit the same late-autumn pattern, as did an F1 on November 25, 1965.
Not every tornado has arrived with winter weather. On May 22, 2008, an EF2 tornado carved a 2.8-mile path some 75 yards wide through the area, injuring one person and causing $350,000 in property damage. EF0 tornadoes touched down that same day, and another EF0 followed on May 23, 2008. Late summer has produced its own entries, with EF0s on August 12 and September 9, 2012.
Recent events have been brief and weak: an EF0 touched down on October 8, 2022, and another on February 23, 2023 — the latter falling squarely in the cool season that has shaped so much of this area's tornado history.
