(dailynews.com) Heavy bands of rain lashed parts of Southern California on Thursday morning, triggering flash flooding and mudslides in some areas recently scarred by wildfires in Orange, San Bernardino and Riverside counties.

By the afternoon, officials had ordered mandatory evacuations for some Malibu homes after a mudslide was reported on Cuthbert Road and from Horizon Drive to Busch Drive. Homes in the area, from Busch Drive to Phillip Avenue were told to evacuate immediately.

The mudslide on Cuthbert Road happened around 3 p.m., forcing road closures in the immediate area, said Matt Myerhoff, spokesman for Malibu. Deputies with the Los Angeles County Sheriff’s Department, and officials with Los Angeles County fire and the public works department are on scene.

The size of the mudslide and if it had damaged any structures was not immediately available.

“We don’t know yet how bad it is, how wide it is, or how extensive it is,” Myerhoff said. “We just know that it happened so we evacuated the immediate area.”

Myerhoff said most of the houses in the evacuation area were burned down by the fire. Though some homes remained intact, and those residents, along with some work crews that were cleaning fire debris from area were evacuated.

Earlier, officials had not seen any sign of mudslides, only reporting a few small rock slides on Malibu Canyon, Kanan Dume and Kanan roads in unincorporated Malibu.

Caltrans vehicles quickly cleaned up rocks in the road in those areas, as well as on Pacific Coast Highway and Mulholland Highway.

There was also a report of light flooding of an access road near Zuma Beach, Hicks said.

Possible new evacuations for neighborhoods in Malibu, Agoura Hills and Calabasas, as well as the sprawling unincorporated areas of L.A. County surrounding those cities, were not issued Thursday.

That was after numerous warnings from county and local officials for residents to be prepared for orders to leave on Wednesday. In anticipation of the rains, public works officials and volunteers sandbagged some neighborhoods and set up k-rails along local roads.

The concern about possible mudslides in fire-charred areas will linger for months, if not longer — Hicks said sheriff’s officials were prepared for rains in the forecast into next week and beyond.

Motorists on the regions’ freeways may have suffered the worst toll of the rains early on Thursday – there were closures from several jackknifed big rigs.

At least one rescue was reported at around 10 a.m., with firefighters airlifting a man trapped in the swollen Los Angeles River near Griffith Park.

Anticipating traffic problems and complications from the rain, some institutions and attractions closed for the day. Pepperdine University announced that classes were canceled Thursday at its Malibu campus.

In Long Beach, flooding on the first floor of City Hall forced the closure of some offices for part of the day.

Mudslides in San Bernardino and Riverside counties also tangled traffic on some canyon roads where wildfires recently burned. On Highway 38, several vehicles were trapped when rain triggered a rock slide in the San Bernardino National Forest. And in Corona, a mudflow shut down Trabuco Canyon Road for hours.

Residents near the Holy Fire burn area in Orange County were asked to evacuate, and officials there reported flash flooding in some riverbeds.
