The National Weather Service says the tornado that struck five miles outside of Stockton, Calif. on Wednesday was not unusual for this time of year.
The twister on farmland near Interstate 5 left a path of damage about a mile long. The Record of Stockton reported that it shredded a wood-frame shop, tipped over a big-rig trailer and sent shards of aluminum siding across more than an acre of land.
National Weather Service Meteorologist Stefanie Henry says it also took the shingles off the roof of a home.
There were no reports of injuries.
Henry says California averages about eight tornadoes a year.
