In photos: Tropical Storm Hilary unleashes flooding and mudslides in California

Los Angeles officials said Monday morning that there had been no known reports of deaths or major damage from Tropical Storm Hilary, as officials throughout Southern California begin to assess the storm’s toll. The storm, which no longer has tropical characteristics, swept through the deserts of California, Arizona and Nevada on Sunday, bringing brief but heavy downpours and record rainfall. Some of the effects were already evident Monday: deserts deluged with rainwater, motorists pushing broken-down cars across highways, disrupted air travel and mass power outages. Correction: A previous version of this visual presentation included a caption with the first photo that incorrectly identified the roadway in the photograph as Interstate 10. The road pictured is Ramon Rd. The caption has been updated.

Much of the damage from Tropical Storm Hilary — which deluged Southern California with heavy winds and torrential rainfall before weakening into a post-tropical cyclone as it crossed the border into Nevada early Monday — is expected to become clear at daybreak. Hilary is likely to bring “catastrophic and life-threatening flooding” to portions of the Southwestern United States and the Baja California region in Mexico through Monday, the National Hurricane Center warned. Tens of millions of people were under a tropical storm warning, the first of its kind issued for Southern California. Heavy rainfall and flooding are expected in parts of Arizona and Nevada.
