Severe weather conditions brought by a powerful atmospheric river event have put over 12 million people at risk of flooding in California. The West Coast has been experiencing heavy rain, snow, and strong wind gusts, with the atmospheric river driving these weather patterns. The progression of this event will move from north to south over the next 48 hours, affecting various regions along the West Coast.
The Pacific Northwest is expected to be the first to experience the impacts of this atmospheric river, with the moisture moving southward into the California Central Valley, coastal regions, and the Bay Area. By Thursday, the focus will shift to southern California. The concentration of rainfall will depend on the location where the plume of moisture sets up, resulting in flood watches being issued in anticipation of its arrival.
