Atmospheric River Prompts Evacuation Orders Across Southern California

On November 14, 2025, a powerful atmospheric river is set to hit Southern California, bringing a deluge of torrential rainfall that threatens millions of residents with the risk of severe flooding. The National Weather Service has issued a flood watch for the region, warning of the potential for widespread flash flooding and debris flows, particularly in areas near recent wildfire burn scars.

In response to the impending storm, Los Angeles County officials have issued evacuation orders for an indeterminate number of homes that are at higher risk of mud and debris flow impacts. The orders, which went into effect on Friday night at 8 p.m. local time and will remain in place through Sunday morning, target properties located near the Canyon, Bethany, Eaton, Palisades, Hurst, Kenneth, Sunset, Lidia, Franklin, and Bridge burn scars.

According to the National Weather Service, the primary, life-threatening concern is the excessive rainfall that is expected to result in flooding of roads, rivers, creeks, streams, and other low-lying and flood-prone locations, including Highway 101. The atmospheric river, a long, narrow region in the atmosphere that transports most of the water vapor outside of the tropics, is known for bringing heavy snow, heavy rain, and strong winds, which can trigger deadly flooding, mudslides, and widespread power outages.

While the storms can also bring beneficial snow that helps supplement reservoirs throughout the summer dry season, the current situation poses a significant threat to the safety of people and animals, as well as the potential for widespread property damage in the affected areas.
