The meteorologists from San Diego said they received reports Sunday from two weather spotters who said they saw two funnel clouds in the area, The (Riverside, Calif.) Press-Enterprise reported Sunday.
Roger Pierce, of the National Weather Service in San Diego, said one spotter said he saw the tornado touch the ground.
"He said he saw debris in the air, so it was picking up brush and dirt," Pierce told the newspaper.
He said he did not know if the tornado caused any damage.
Severe weather in other parts of the Inland area in Southern California did cause damage Sunday, California Highway Patrol Deputy Albert Martinez said.
Martinez said wind gusts blew down at least two utility poles and damaged roofs in Perris.
