Crews have reopened some Southern California roads that were buried in tons of mud during flash flooding.

Los Angeles County crews on Sunday reopened stretches of five roads in mountain communities about 40 miles north of Los Angeles.

Work continues on two other roads that were inundated as thunderstorms unleashed flash flooding on Thursday.

In nearby Kern County, more than 100 cars, buses, RVs and big-rig trucks were trapped on State Route 58. All but a handful have been pulled free and the work continues.

The region got some drizzle Sunday but there wasn't any serious rain and the cleanup wasn't affected.
