Powerful bomb cyclone to bring heavy rain and snow to US West Coast

A powerful "bomb cyclone" is set to hit the U.S. West Coast this week, bringing hurricane-force winds, heavy rain, and snow. It could release up to 8 trillion gallons of rain, raising concerns about flash floods and landslides in California and nearby states. This storm forms through a process called bombogenesis, where a low-pressure system rapidly intensifies. The current system is expected to drop nearly 70 millibars in 24 hours, similar to a Category 4 hurricane, and will merge with a strong atmospheric river. States like Oregon and Washington are also preparing for significant rainfall, with forecasts predicting 5 trillion and 3 trillion gallons, respectively. Authorities are advising residents to stay alert and follow weather updates as the storm approaches.
