Flood in Kern County, California

California Highway Patrol reported mud from a mud slide covering two westbound lanes of SR 58 at Comanche Dr.

A frontal boundary associated with an upper trough pushed through central California between the afternoon of February 20 and the morning of February 21. Scattered showers and thunderstorms developed along the boundary and many locations in the San Joaquin Valley picked up an additional quarter to half inch of rainfall as a result. Several stations in the Sierra Nevada and adjacent foothills picked up an additional half inch to an inch of additional liquid precipitation with several SNOTEL stations north of Kings Canyon picking up an estimated 5 to 10 inches of new snowfall. The frontal boundary stalled over Kern County during the early morning of February 21 resulting in nuisance flooding along several highways. The showers ended by late morning.
