.FOR CALIFORNIANS it seemed like remembrance. Last year a ceremony of hurricanes, sustained through atmospherical streams, eliminated at least 21 individuals as well as resulted in almost $5bn-worth of damages across the condition. On February 4th this year the very same kind of tornado once more wreaked havoc. Hurricane-strength winds buffeted the main shore near Significant Sur. In Los Angeles personalities were soaked as they arrived at the Grammy honors' ceremony. Mansion houses in the Hollywood Hills were actually dealt with in mud. At least three people have actually perished. What are actually atmospherical rivers, as well as are they a hazard beyond The golden state?
