Rare Southern California rains have triggered mudslides in an area of the Los Angeles-area foothills scorched bare by a wildfire earlier this year.

Los Angeles County Fire Department Dispatch Supervisor Robert Diaz says a 4-foot-high flow of debris hit a home in the suburb of Glendora before dawn Friday.

Diaz says an earlier debris flow covered a vehicle in the driveway of the residence.

Authorities say mud flowed onto several residential streets, but no closures were announced.

The National Weather Service issued a flash flood warning after a storm dumped hail and heavy rain across the foothills of the San Gabriel Mountains from Pasadena to as far east as Claremont.

Earlier this year, the Colby Fire burned nearly 2,000 acres of brush in the hills above Glendora.
