An unusually potent storm system is saturating Los Angeles and Southern California, elevating the threat of dangerous flash flooding and destructive mudslides, particularly in neighbourhoods previously ravaged by wildfires. The multi-day atmospheric river event is expected to maintain a moderate to high risk through Saturday, prompting officials to issue evacuation warnings.
Intense Rainfall and Severe Weather Threats
The Los Angeles area is bracing for torrential downpours, with forecasts predicting rainfall rates of up to one inch per hour in some locales for the majority of Saturday. According to the National Weather Service, the relentless rain is projected to finally taper off and conclude on Tuesday. Meteorologist Joe Sirard noted that if the precipitation continues as expected, this could become the wettest November for the region since 1985.
Adding to the severe weather profile, the storm carries a chance of thunderstorms and even a weak tornado, driven by a spinning low-pressure system moving toward the coast. As of Saturday morning, downtown Los Angeles had already recorded 1.32 inches of rain, significantly surpassing the entire November monthly average of 0.78 inches.
Evacuation Warnings and High-Risk Zones
City and county emergency crews are on high alert as the deluge significantly increases the danger of debris and mud flows in vulnerable burn scar areas. Specific concerns are focused on the Eaton and Palisades burn scars. In response, evacuation warnings remain in effect for many communities impacted by the deadly January fires, with those warnings valid through 8 a.m. on Sunday.
Flood watches have been activated across large portions of the Los Angeles area, as well as in Santa Barbara and Ventura counties. These watches are anticipated to be lifted by Saturday night, but the situation remains fluid and dangerous for residents in at-risk zones.
A Region on Edge
The scene on the ground reflects the severity of the forecast. Photos from the storm, such as those taken at a Pasadena farmer's market, show residents navigating the conditions amid ongoing flash flood alerts. The persistent nature of this storm system underscores the long-term vulnerabilities created by wildfires, where denuded landscapes lose their natural ability to absorb heavy rainfall. The coming days will be a critical test for the region's infrastructure and emergency response capabilities as it endures one of the most significant November weather events in decades.
