Bomb cyclone forms off West Coast bringing heavy rain and high winds

kcra.com

A bomb cyclone is a rapidly intensifying storm that occurs when a cyclone's atmospheric pressure drops significantly, typically by 24 millibars or more in 24 hours. This phenomenon often happens when cold and warm air masses collide, especially over ocean waters. Currently, a bomb cyclone is forming off the West Coast, impacting northern California and the Pacific Northwest. This storm is expected to bring heavy rainfall, flash flooding, and high winds, with hazardous travel conditions and potential power outages. Bomb cyclones can occur in various ocean regions, not just the West Coast. Recent examples include Hurricane Milton in Florida and a notable storm in 2018 that affected the Southeast with heavy snow and strong winds.
