Rain fell on many parts of the region overnight, with thunder and lightning also waking some residents in the early morning hours. Lightning was spotted off the South Bay coast Wednesday morning, prompting Los Angeles County lifeguards to close the beaches and usher swimmers out of the water from San Pedro to Hermosa Beach.
In Riverside County, a flood advisory is in effect until just after 3 p.m. that includes the Fairview Fire burn area.
The fire started Sept. 5 on Fairview Avenue and Bautista Road and became California’s largest wildfire of 2022. Two people, a father and daughter, were killed when they tried to escape flames and at least 36 structures were destroyed.
Thunderstorms, rain and hail were reported early Wednesday afternoon in the San Bernardino County mountains.
The conditions are due to an area of low pressure that will likely remain in place for the rest of the week. The best chances for rain will be in the mountains and deserts, but coastal areas will likely continue to see isolated storms.
