.FOR CALIFORNIANS it felt like remembrance. Last year a procession of hurricanes, fuelled by atmospherical streams, gotten rid of at the very least 21 people and also created almost $5bn-worth of harm across the state. On February fourth this year the exact same form of tornado once again ravaged. Hurricane-strength winds buffeted the core coastline near Significant Sur. In Los Angeles famous personalities were actually soaked as they came to the Grammy honors' ceremony. Manors in the Hollywood Hills were actually dealt with in dirt. At least 3 folks have actually passed away. What are atmospherical rivers, and are they a hazard past California?
