.FOR CALIFORNIANS it seemed like remembrance. In 2015 a march of tornados, fuelled through climatic rivers, gotten rid of at the very least 21 people and induced almost $5bn-worth of damages all over the condition. On February 4th this year the exact same sort of hurricane once more created chaos. Hurricane-strength winds buffeted the main shore near Large Sur. In Los Angeles celebrities were saturated as they came to the Grammy awards' red carpet. Mansions in the Hollywood Hillsides were dealt with in mud. At the very least 3 folks have perished. What are atmospheric rivers, and are they a hazard beyond The golden state?
