Up to 4 inches of rain could fall in San Luis Obispo County, resulting in flood risks, the National Weather Service says.

Heavy rain led to flooding on a stretch of the northbound 710 Freeway in Long Beach on Saturday afternoon, prompting a SigAlert and traffic delays.

Fresno has already received an inch of rain from a slow-moving storm and much more is on the way, as the rain could last through Monday.

A North Pacific storm that’s drawing moisture from the subtropics could drop 1.5 inches to 3 inches of rain at the coast and 3 inches or more inland Friday and Saturday across San Diego County, largely bringing fire season to an end, the National Weather Service said.
