The strongest and wettest storm in this weather pattern will arrive Sunday along the West Coast.
Very heavy rainfall will accompany this storm in Northern California and parts of the Pacific Northwest since it will tap into a potent atmospheric river of moisture.
In fact, according to the National Weather Service, this atmospheric river Sunday could contain a record amount of moisture for October for the Bay Area and central coast.
The Center for Western Weather and Water Extremes is forecasting a Category 5 atmospheric river event for the San Francisco Bay Area, meaning a prolonged and extremely wet plume of moisture is expected throughout the weekend.
