On Tuesday, California’s Central Valley experienced rare tornado activity, with three tornadoes reported in rapid succession, according to early data from the national weather bureau.
This stormy weather hit Fresno and Madera counties with intense rainfall, strong winds, and hail. Thankfully, there were no reports of injuries or major damage.
Although numerous funnel clouds were seen, only a few developed into tornadoes, meeting the official criteria.
The first tornado touched down near Viola at 2:10 p.m.
Experts describe the Central Valley as a sort of “mini-tornado alley,” with its flat landscape resembling that of the Great Plains.
Most tornadoes in California tend to be on the weaker side, rated at EF0 or EF1.
A short-lived tornado impacted a walnut grove, packing winds of 110 mph and carving out a path about 150 feet long—roughly half the length of a football field. It was classified as an EF0.
Another tornado followed about an hour later, west of Atwater. This one was more powerful, reaching wind speeds of 95 mph and traveling half a mile while damaging trees; it earned an EF1 rating.
The third tornado developed northeast of Clovis at 5:09 p.m. It was comparable in distance to the second but had a greater impact, with winds hitting 110 mph and causing damage to several homes.
Officials suggest that 20 funnel clouds may have been visible during this storm. While such formations can occur in the area, most don’t touch down.
March tends to be the most active month for tornadoes in California, particularly around 3 p.m.
It’s important to note that tornadoes remain relatively infrequent in California. Data indicate that only 487 tornadoes have been confirmed in the state from 1950 to 2025, with days seeing three or more tornadoes being exceptionally rare—only about 20 occurrences during that timeframe.
The Central Valley and coastal Southern California are where most tornado activity takes place, with Los Angeles County reporting the most, although higher population density may skew detection rates.
This recent tornado event was likely due to a unique mix of atmospheric conditions. A humid system from the Pacific Ocean, combined with daytime heating as clouds cleared, created the instability needed for thunderstorms and tornado development.
