West Coast Prepares for Intense Bomb Cyclone and Atmospheric River

A 'bomb cyclone' is expected to hit the West Coast, particularly California and Oregon, from November 19 to 21, bringing high winds, heavy rains, and potential flash flooding. The storm will undergo 'bombogenesis,' a rapid pressure drop, intensifying its impact. Areas from the San Francisco Bay to Eureka, California, will experience extreme conditions, with wind gusts up to 70 mph and rainfall of 2 to 4 inches per day. This event highlights the shifting patterns of atmospheric rivers due to climate change, which could lead to more immediate flooding and less snowpack, affecting water supplies.
