More rain expected in California on 2nd day of summer storm

More rain is expected Sunday in the second day of a summer storm that has brought beach closures, flash floods and power outages along with thunder and lightning to Southern California.

The region was expected to receive scattered showers again Sunday, with downpours in some areas, as remnants of tropical storm Dolores off Baja California bring warm, muggy conditions northward, said National Weather Service meteorologist David Sweet.

The unusual weather turned Los Angeles County's typically packed coast into empty stretches of sand when the threat of lightning forced authorities to close 70 miles of beaches Saturday. The popular Santa Monica Pier and its nearby beaches were also shuttered.

Last summer, a lightning strike killed a man at Venice Beach and injured about a dozen people.

Los Angeles County's beaches were open Sunday, despite reports of potential thunderstorms in the afternoon, said AJ Lester of the Los Angeles County Fire Department's Lifeguard Division.

Lester said he has been in touch with weather officials and was tracking reports of afternoon rain.

Signs warned beachgoers to avoid storm drain flows into the ocean because of Saturday's sometimes heavy rain. The Los Angeles County Department of Public Health recommends people avoid swimming within 100 yards of a storm drain for 72 hours after heavy rain.

"All storm drains flowed out yesterday, but it hasn't rained much this year, so that doesn't bode well for the water quality," Lester said Sunday.

Warnings were also in place for high surf and strong rip currents on all south-facing beaches, including Venice, Santa Monica, Malibu, Zuma, Newport and Huntington, Lester said.

The storm dropped as little as a quarter-inch of rain in downtown Los Angeles and as much as 2 inches in the mountains of Ventura County on Saturday. It was expected to bring about the same amount Sunday.

The summer storm has helped firefighters advance on two wildfires that broke out Friday.

Muggy conditions, meanwhile, were expected to persist through Monday.
