A storm of historic proportions unleashed record levels of rain over parts of Los Angeles on Monday, sending mud and boulders down hillsides dotted with multimillion-pound homes, posing a grave danger to the city’s large homeless population and knocking out power for more than a million people in California.
The storm was the second one fuelled by an atmospheric river to hit the state in just a few days.
About 1.4 million people in the Los Angeles area, including the Hollywood Hills and Beverly Hills, were under a flash flood warning on Monday.
