A bomb cyclone is intensifying off the West Coast, predicted to produce excessive rainfall, high winds, and winter storms. Over seven million residents face flood risks, and impacts are expected to worsen through the week, particularly in northern California and the Pacific Northwest. NOAA warns of potential flash flooding, debris flows, and blizzard conditions along with significant snowfall in mountain regions. The storm is linked to an atmospheric river, amplifying its effects, with the potential for power outages and hazardous travel as conditions peak.
