Bomb cyclone approaches West Coast bringing heavy rain and high winds

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 approaching the West Coast, affecting northern California and the Pacific Northwest. The National Weather Service has issued warnings for excessive rainfall, flash flooding, and high winds due to this storm's intensity. Bomb cyclones can occur in various ocean regions, not just the West Coast. They have been linked to severe weather events across the U.S., including hurricanes and extreme winter storms in recent years.
