Light rain is forecast for most of LA County this weekend

Temperatures will remain cool for the most part this weekend, but there will be less precipitation than previously expected in Los Angeles County as a storm system north of the area has stalled, according to the National Weather Service.

Southern California could receive a quarter of an inch to a third of an inch of rain early Sunday, according to NWS meteorologist Carol Smith, with most of the moisture hitting northwestern communities near the Grapevine, north of LA County.

But the Los Angeles Basin is expected to receive just a tenth of an inch of rain over the same period, while neighboring Ventura County could get up to half an inch of rain, forecasters said.

The first of two storms moved south from California’s Central Coast on Thursday. Light rain was reported in the valleys and west of Los Angeles on Friday.

Downtown Los Angeles recorded a tenth of an inch on Friday, while surrounding areas claimed no more than a third of an inch of rainfall. The San Fernando Valley received the most rain, with Porter Ranch receiving 1.24 inches, Northridge 0.64 inches, and Van Nuys a third of an inch.

Most of Los Angeles County received less than a half inch of rain on Friday.

The initial storm system was expected to deliver more county-wide rainfall, according to the NWS, but estimates changed as the main front stalled over Ventura County. Portions of the storm even shifted north, away from Los Angeles County.

A second storm moved into the area late Friday night and is expected to last through Saturday. However, the National Weather Service said its path remains in flux and the storm could advance further into Los Angeles County on Sunday.

Parts of Santa Barbara and San Luis Obispo counties are under flash flood warnings, while Santa Lucia, San Luis Obispo and Santa Barbara mountains have wind warnings through 3 a.m. Sunday
