Part 3/6:
The Big Wave of Rain and Snow
Early Tuesday morning marks the beginning of the heaviest rainfall. A cold front, originating from the Pacific Northwest, will sweep through Northern California tonight, gradually descending into Southern California by late Tuesday morning. This system will bring:
4 to 6 hours of moderate to heavy rain, mainly during the morning and early afternoon.
Potential thunderstorms and waterspouts, especially along shorelines, due to the cold air interacting with the moist subtropical air supplied by Tropical Storm Purcell, which has contributed significant moisture to the region recently.
