A significant storm is set to impact the West Coast, heralding the arrival of a phenomenon known as a bomb cyclone.
The term “bomb cyclone” refers to a meteorological event characterized by rapid intensification, also called bombogenesis. This occurs when atmospheric pressure plunges swiftly, typically involving the clash of cold and warm air masses, often over ocean waters. According to the National Oceanic and Atmospheric Administration, a bomb cyclone is defined as a cyclone that experiences a decrease of at least 24 millibars in atmospheric pressure within a 24-hour period.
Northern California and the Pacific Northwest are bracing for this intense meteorological event, exacerbated by an atmospheric river—an extended corridor of moisture originating from the Pacific Ocean. The National Weather Service’s Weather Prediction Center has issued warnings of excessive rainfall from Tuesday through Friday, anticipating heavy rainfall, flash flooding, and winter storm conditions at varying elevations.
Predictions indicate that the storm will generate powerful winds, heightening the risk of hazardous travel and widespread power outages, while also potentially causing significant damage to trees and infrastructure.
While bomb cyclones are expected to make their mark on the West Coast, it’s crucial to note that they can occur in multiple regions worldwide, including different parts of the Northwest Pacific and North Atlantic.
Historically, bomb cyclones have been linked to major weather events across the United States. One recent example is Hurricane Milton, which made landfall in Florida last month. In 2018, a bomb cyclone contributed to winter weather across the Southeast, bringing hurricane-force winds, while another event in 2022 led to intense cold and extreme weather across America.
As the country prepares for this storm, there is one silver lining to note: communities often come together in the face of such challenges, showcasing resilience and solidarity. It’s crucial for residents to stay informed and prepare adequately to ensure their safety during the impending storm.
