by Los Angeles County, CA – Portions of California, Arizona, and Nevada are under a flood watch as a powerful storm moves eastward from Los Angeles County into the Mojave Desert, officials said Monday. Authorities warn that heavy rainfall could trigger rapid runoff and flash flooding in sensitive regions.
Recent Storm Impact Across Southern California
A strong atmospheric river storm recently drenched Los Angeles County and other parts of Southern California, causing widespread flash flood warnings and fatalities. The National Weather Service (NWS) highlighted that areas impacted by recent wildfires remain particularly vulnerable to life-threatening mudslides and debris flows, increasing risks to both lives and property.
Flooding continues to rank as the second deadliest weather hazard in the United States, emphasizing the importance of remaining vigilant in the face of severe storms.
Areas Under Flood Watch
The NWS has issued a flood warning for Los Angeles County until 9 p.m. PT Monday, covering locations such as Burbank, Pasadena, Altadena, and the Eaton burn scar. As the storm progresses east, portions of the desert southwest—including Death Valley National Park, Eastern Mojave Desert, Owens Valley, and San Bernardino County-Upper Colorado River Valley—are now under a flood watch.
In Arizona, the watch includes Lake Havasu, Fort Mohave, Lake Mead National Recreation Area, and portions of the northwest desert regions. Nevada residents in areas such as the Lake Mead region, Las Vegas Valley, northeast, southern, and western Clark County, as well as southern Nye County, should also remain alert. The watch is in effect from 10 p.m. PT Monday through late Tuesday night.
Storm Hazards and Safety Concerns
The NWS warns that heavy rainfall will combine with already saturated soils, increasing the potential for rapid flooding in sensitive basins. Embedded thunderstorms may produce localized heavy rainfall, while areas previously impacted by wildfire remain at risk for mudslides, debris flows, and rock slides.
On social media, NWS Los Angeles cautioned:
“There’s been areas of heavy downpours & some wind with the main front, and these heavier showers can lead to localized flooding issues, mud and rock slides, downed trees, and reduced visibilities. Turn around, don’t drive through flooded roadways.”
Similarly, NWS Las Vegas advised:
“Heads up! Another round of heavy rain is on the way which could lead to localized flooding. Be mindful of flood-sensitive basins, washes, and be prepared to seek higher ground if you encounter flood waters.”
What Residents Should Do
Authorities urge residents in California, Arizona, and Nevada to monitor local forecasts and stay alert for Flood Warnings. Drivers are reminded never to attempt crossing flooded roads, as even shallow water can be deceptive and dangerous. Seeking higher ground during flash flood warnings can prevent injuries or fatalities.
