los Angeles Braces for Potential Burn Scar Flooding as Storm Approaches
Los Angeles County is under a flood watch as a powerful storm system moves into Southern California, raising concerns about risky debris flows from recently burned areas. Authorities are urging residents near wildfire burn scars to prepare for potential evacuations,with a particular focus on communities below the Bobcat,Route,and Ranch Fires.The National Weather Service predicts rainfall rates exceeding one inch per hour in some areas, creating a high risk of mud and debris inundating canyons and roadways.
The threat stems from the altered landscape left by wildfires. Vegetation that once anchored soil is now gone, leaving hillsides vulnerable to erosion when heavy rain falls. This creates a slurry of mud,rocks,and vegetation that can rapidly flow downhill,posing a meaningful danger to life and property. Los angeles County has invested heavily in post-fire mitigation efforts, including debris basins and clearing drainage channels, but the sheer intensity of the anticipated rainfall presents a substantial challenge.
County officials have activated emergency operation centers and are closely monitoring conditions. Mandatory and voluntary evacuation warnings have been issued for several areas, including parts of Topanga Canyon, Malibu, and Acton. Residents in these areas are encouraged to heed warnings and prepare go-bags with essential supplies.
“Even a moderate amount of rainfall on these burn scars can trigger significant debris flows,” warned Los Angeles County Public Works Director Mark Pestrella during a press conference Tuesday. “We’re doing everything we can to prepare, but residents need to be vigilant and take this threat seriously.”
The storm is expected to impact the region through Wednesday, with the heaviest rainfall occurring overnight. Following the storm, crews will work to assess damage and clear debris from roadways.
