A rapidly intensifying storm, which meteorologists describe with the fancy term "bombogenesis," is developing in the Pacific and forecast to hit the state Friday night.
The process of bombogenesis occurs when a low pressure storm system intensifies rapidly, or "bombs out." To qualify, the minimum central air pressure must drop 24 millibars in 24 hours.
