Rain triggers mandatory evacuation order in Orange County’s Silverado, Williams, Modjeska canyons due to mudslides

A mandatory evacuation order will be in effect for residents living in Orange County’s Bond Fire burn area starting 8 p.m. Wednesday as another round of rain moves into Southern California.

The mandatory evacuation will be for residents living in the Silverado, Williams and Modjeska canyon areas due to fears of possible debris flows near the burn scar area.

“Canyon residents are strongly encouraged to evacuate prior to 8 p.m. Hard road closures will be in effect at 8 p.m. and access in and out of the canyon will be restricted to public safety and public works vehicles,” officials said in a statement.

A voluntary evacuation warning was previously in effect earlier on Wednesday.

The same areas were subjected to mandatory evacuations during last week’s storm, and residents have since been clearing up the remnants of damage, including downed trees and muddy roads.

Modjeska Canyon resident Marcus Lynch said earlier this month a 65-foot Magnolia tree fell onto his home.

With the consecutive storms, he says he hasn’t had much of a chance to properly shield his home from the rain.

“I couldn’t start and I haven’t started and I don’t know when I’m going to be able to start,” he said ahead of the incoming storm.

The National Weather Service issued a flash flood watch for Orange County coastal and inland areas and the Santa Ana Mountains, including the Bond Fire burn area. The watch will be in effect Wednesday morning through Thursday afternoon.

“Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations,” according to the NWS. “Flooding may occur in poor drainage and urban areas. Flash flooding and debris flows are possible, especially near recent burn scars.”

NWS forecasters for Orange County said the area could receive up to 2.5 inches of rain along the coast and as much as 6 inches in the mountains below 5,000 feet, with an hourly rainfall amount of 0.6 to 0.7 inches possible.

Southern California’s mountain communities are also expected to see more snow.

A winter storm warning took effect at 1 a.m. Wednesday and will remain in place until 4 a.m. Friday in the Los Angeles County mountains, excluding the Santa Monica range. According to the National Weather Service, “heavy snow” is possible, with 1 to 3 feet accumulating above 5,000 feet, and “light snow” falling as low as 4,000 feet. The snow will be accompanied by winds of 35 to 40 mph, with higher-elevation gusts of up to 60 mph.

“Travel could be very difficult to impossible,” according to the NWS. The weather service said that some mountain roadways that could be affected by snowfall include Angeles Crest Highway, Mount Baldy Road and Highway 39.

Caltrans later said workers were clearing Angeles Crest Highway in the Angeles National Forest north of La Canada Flintridge, and chains were required.
