The brunt of the storm's fury Monday centered on the Los Angeles area, where 1.4 million people were under a flash flood warning – including the Hollywood Hills and Beverly Hills. A local state of emergency was issued for the city of Los Angeles by Mayor Karen Bass on Monday afternoon.
Across Southern California, the heavy winds that blasted the region Sunday were diminishing, but the National Weather Service warned that an unstable weather pattern could generate waterspouts or small tornadoes.
