The West Coast is bracing for a powerful bomb cyclone expected to unleash heavy rain, strong winds, and significant snowfall across California, Oregon, and Washington. This storm system, described as a bomb cyclone, is set to bring extreme weather, with forecasters warning of life-threatening conditions, particularly along the Pacific Northwest. An atmospheric river accompanying the cyclone is likely to cause flash flooding and mudslides in burn zones, especially in Northern California, while the Bay Area prepares for up to five days of rain. Travel disruptions are anticipated in ski regions like Tahoe and the Sierra Nevada due to back-to-back storms. As the bomb cyclone approaches, residents are urged to prepare for damaging winds and potentially up to 15 inches of rain in certain areas.
