Hail, thunderstorms visit Los Angeles as storm rolls through

Low-pressure system brings rain, hail, lightning to parts of Southern California

A low-pressure storm system sweeping through Southern California brought rain, scattered thunderstorms and some hail late Wednesday as officials warned of possible floods and dangerous road conditions.

Showers were expected across the Los Angeles Basin through the evening, with heavier storm cells bringing thunderstorms and downpours to parts of the San Fernando Valley and San Gabriel Mountains.

Some areas around the Antelope Valley saw hail measuring up to 1 inch. Palmdale also saw about a third of an inch of rain.

A flash-flood warning also was in effect in the Antelope Valley until at least 8:30 p.m., according to the National Weather Service. Officials warned that long after the rain has stopped, dry washes and canyons may have fast-flowing streams caused by the rainfall.

The hail was part of a severe storm that pummeled areas just north of Santa Clarita, but warnings were lifted after 8 p.m., once the storm had "weakened considerably," according to the Weather Service.

Still, rains were expected to roll over the valleys toward the coast, with storm cells stretching from San Clemente to Malibu.

Slick roads -- including a half-inch of rain on the Pearblossom Highway in Llano -- presented hazards to motorists.

In Lancaster, seven people were injured in a three-car collision, according to the Los Angeles County Fire Department, which transported five people to the hospital.
