Showers and thunderstorms were expected across Southern California on Saturday, potentially threatening hillsides ravaged by fires.
Forecasters said an upper-level low-pressure system off the coast of Baja California would move eastward later in the day and into Arizona by Sunday, wrapping instability and more moisture around a low-pressure system that was already bringing a heavy sea layer.
The thunderstorms are forecast south of Point Conception, primarily in Los Angeles counties and east Ventura, according to the National Weather Service. Temperatures are in the mid 60’s to low 70’s throughout the day.
Brief heavy rains of between 0.25 and 0.50 inches per hour and isolated spots of 0.75 inches could hit recent fire areas for half an hour at a time, which could cause street flooding, the NWS said.
The storms also have the potential to create abrupt and erratic winds, gusting between 30 and 40 miles per hour, forecasters said.
Given California’s ongoing struggle with drought and fire, storms are often both welcome and a threat to burn scars.
But on Saturday, most of the region, from coasts to valleys, was shrouded in a soft sea layer with light rain, according to the NWS. Expected total precipitation in Los Angeles County is between 0.10 and 0.70 inches and less than 0.25 inches in Ventura County, with up to an inch of rain possible in LA County mountains and near thunderstorms.
The past three years have been the driest in California on record as the state enters a fourth year of drought.
With its Mediterranean climate, the state typically receives 75% of its annual rainfall between November and March.
Saturday’s rain wasn’t enough to ease concerns about falling reservoirs, especially as the rest of California stayed dry.
But it was an early reminder of the season for those eagerly awaiting what the next rainy season will mean for California’s dwindling water supply, and for many on social media, who posted fall praises and photos of their rain boots.
Forecasters said another low-pressure system could bring additional shower activity by next Thursday or Friday.
