Flash Flooding Expected In Malibu, Evacuations Ordered In Burn Scar Areas

Authorities have evacuated a select number of high-risk properties in and near the Franklin and Palisades fire burn scars as a Flash Flood Warning for those areas remains in effect Tuesday morning.

Meantime, residents in a much wider swath Malibu, Pacific Palisades, the Santa Monica Mountains and Calabasas are being told to prepare to leave if necessary as part of Evacuation Warnings for the area.

The Flash Flood Warning is in effect for the area until noon on Tuesday, with an expected rainfall rate of between 1 and 1.5 inches per hour, according to the National Weather Service.

"Excessive rainfall over the burn scar will result in debris flow moving through the areas in and near the Franklin and Palisades Burn Scars. The debris flow can consist of rock, mud, vegetation, and other loose materials. Mud, rock, and debris flows will impact drainages, roads, and residences in these areas," according to an alert from the city of Los Angeles.

The Los Angeles County Sheriff’s Department successfully evacuated a "limited number" of vulnerable properties in and near those fire burn scars by early Tuesday morning. Residents impacted by those orders were notified in a door-to-door operation and via digital alerts, according to the city of Malibu.

Officials took similar efforts in the city of LA. Evacuation orders were in place for 114 homes in the Mandeville Canyon area, five in the Hearst Fire area and one in the Sunset Fire area, according to LAFD spokeswoman Margaret Stewart.

Evacuation warnings remain in effect for Malibu, Pacific Palisades, the Santa Monica Mountains and a small part of Calabasas until Wednesday morning.

Up to date information about evacuation orders and warnings is available on Genasys Protect.
