Residents of California experienced a wet and windy storm on the second day of spring, which delivered more rain, snow and hazards to the Golden State. The storm developed rapidly over the Pacific and made landfall along the Central Coast. The low-pressure system rocked the Bay Area and the Central Coast, with widespread rain and damaging wind gusts snarling traffic, knocking glass out of skyscrapers and leaving tens of thousands without power. The heavy rain is likely to lead to rapid runoff and areas of flooding as the storm moves south. The storm that hit Northern California is known as a “bomb cyclone,” a rare weather phenomenon which occurs when a system's atmospheric pressure drops rapidly, leading to very strong winds. The low-pressure system brought 80 miles per hour wind gusts, knocking down power lines and causing blackouts. Despite having cut California's drought by half, the record snowpack will increase the threat of spring flooding, warn forecasters.
