While rainfall is expected to subside Sunday night into Monday, the risk of flash flooding and mudslides will continue into Monday afternoon in wildfire-burned areas, according to the National Weather Service.
The center of the storm is expected to move over Los Angeles County on Monday, with the highest risk of locally heavy rainfall throughout the day. Ahead of the storm, the National Weather Service issued flood warnings for areas burned by the Palisades, Eaton, Hughes, Franklin and Bridge fires.
At City Hall on Sunday, officials told people affected by the Palisades Fire that the county Department of Public Works has installed 15,000 K-rail guardrails and 50,000 sandbags in the fire area to protect property and the environment.
High-intensity rainfall (more than half an inch per hour) can wreak havoc on burned areas, increasing the likelihood of flooding and landslides in fire-resistant soil. Rainfall rates of 0.39 inches per hour were reported near Pepperdine University, with higher amounts possible.
At 7:40 p.m. Sunday, the National Weather Service raised the flood alert level for areas west of the Franklin Fire Scar and Palisades Scar to a flash flood warning, the highest alert level for possible flooding, until 11 p.m. , rocks and mudslides will affect drainage systems, roads and homes, and although unlikely to occur immediately, mudslides can be life-threatening.
The flood warning will expire at 4pm on Monday.
Rainfall amounts have been highly variable across the region, with parts of Los Angeles receiving more than an inch of rain by 7 p.m. Sunday and other areas receiving less than a tenth. According to the National Weather Service.
The National Weather Service station at Eaton Dam near the burn scar of the Eaton Fire recorded 0.13 inches of rainfall. Monte Nido Station (in the Santa Monica Mountains near the Palisades Fire burn scar) recorded 0.55 inches.
