Harry and Meghan, George Clooney, Lady Gaga and Halle Berry are among the celebrities whose multi-million dollar mansions are threatened by severe storms in California this week.

The Pineapple Express, a weather system affecting much of the Sunshine State, is causing chaos in several regions, including the star-studded neighborhoods of Beverly Hills, Malibu and Montecito.

The National Weather Service has issued flash flood warnings for several neighborhoods in California and some residents have even been evacuated.

In a dramatic operation in the early hours of Monday morning, LA firefighters rescued 16 people from nine properties in Studio City – the same neighborhood where George Clooney lives in his $2.2 million luxury home.
