New Storm Brings Continued Rain and Flood Concerns in Southern California

A flood advisory remains in effect across the Los Angeles region until 2:45 p.m. Sunday, as the National Weather Service predicts excessive rain to cause urban and other small streams to flood, and water to pool in low-lying and poor drainage areas.

Continued Rainfall and Potential Hazards

The weather system is showing a “certain amount of rotation” over the L.A. area, increasing the chances of thunder, heavy downpour, local lightning, and gusty winds, according to Rose Schoenfeld, a meteorologist with the National Weather Service.

New Storm Predicted for Monday Morning

A different storm system off the coast Sunday morning is expected to hit metro L.A. mid-morning on Monday, bringing heavy rain that will “keep things pretty rainy,” according to Schoenfeld.

Flash Flood Warnings and Burn Areas

The weather service also warned of debris flows in recent burn areas, including the Eaton, Bridge, Franklin, Hughes, and Lidia burn scars. Flooding is predicted across the region from Long Beach to Pasadena, downtown through Hollywood, into the San Fernando Valley, and in coastal areas such as Santa Monica.

By Saturday afternoon, the storm system had already drenched Greater Los Angeles with 2-3 inches of rain, and up to 8 inches in some areas. The rains have helped dampen fire danger and replenish water supplies for Southern California but also caused their own emergency conditions, including flash flooding.

County officials advised residents to “remain alert” for hazards. Evacuation orders had been in place in various parts of the county but were lifted Saturday evening.

Industry Context and Expert Analysis

The atmospheric river that brought the initial heavy rainfall has intensified, posing a significant flood risk across Southern California. Meteorologists predict more intense bursts of rain over the next several hours, with the potential for mudslides in burn areas.

Experts warn that saturated soils from previous storms increase the likelihood of dangerous conditions, particularly as new systems bring additional moisture to an already water-logged landscape.

“Given how saturated soils are already, we’re seeing increased falling trees and the risk of flash flooding,” said Schoenfeld. “Residents should stay informed and be prepared for potential hazards.”
