SILVERADO CANYON, Calif. (KABC) -- Orange County firefighters rescued trapped residents as Tuesday's storm triggered multiple mudslides in Silverado Canyon and other burn areas.

A mandatory evacuation order had been issued for the Bond Fire area, including Silverado, Williams and Modjeska canyons, due to "imminent debris flows along or near the burn scar."

Video from the scene showed mud flows rushing down the hills. Residents were warned to stay away from the area.

Mud is flowing downhill in Silverado Canyon in this video from the Orange County Fire Authority. Firefighters have rescued trapped residents.

A map with a detailed look at the areas under evacuation is available here. Affected residents can go to the Lake Forest Sport Park, 2800 Rancho Parkway, after 4 p.m.

The first big storm of the season slammed Southern California on Tuesday with rain, high winds and mountain snow, leading to growing concerns about mud and debris flows in recent burn areas. By 8 a.m., some mountain and foothill areas had already received as much as 7 inches of rain, while coastal and valley areas had received between 1 and 3 inches, according to the National Weather Service.

The NWS issued a flash flood watch that will be in place until 6 p.m. in recent burn areas -- from the Bobcat, Ranch 2, Dam, Lake and Palisades fires. Forecasters warned that those areas could see intense downpours with an inch or more of rain per hour.

"Residents near these burn scars should prepare for potential flash flooding and debris flow impacts,'' according to the NWS.

The Red Cross also opened a shelter at Redlands East Valley High School, 31000 E. Colton Ave. in Redlands, and the American Red Cross of Riverside County opened a shelter at the Albert A. Chatigny Senior Community Center, 1310 Oak Valley Parkway in Beaumont.

In San Bernardino County, heavy rain triggered debris flow along street in Yucaipa - one of several areas near the El Dorado and Apple fire burn stars which was placed under a mandatory evacuation order.

Heavy rain pounded the Inland Empire Tuesday, triggering a rush of debris flow along local streets in Yucaipa.

In Monrovia, residents in the foothill areas were keeping a wary eye on the Bobcat Fire burn scar. Homeowners near Ridgeside Drive and Oakglade Drive, who were under an evacuation warning, had piled sandbags on their property to defend against possible mudflows.

In Santa Barbara County, residents of mountain communities near the Alisal Fire burn scar were ordered Monday to evacuate over concerns that heavy rains might cause flooding and debris flows that could inundate hillside homes.
