Here is the latest AccuWeather Regional Radar of California:
The National Weather Service in San Francisco offers this advice:
Sunday is still looking very wet...We know many of the folks that live in the hills from Sonoma to Santa Cruz and Big Sur are hearty and resourceful, but this storm will bring several inches of rain so please take appropriate precautions so that lives are not lost.
Please pay attention to the [flood products] issued if you live near rivers such as the Napa, Russian and San Lorenzo. Even the Pajaro and Carmel river which haven't flooded in many years may get close by Monday with serious rises on the Big Sur river, as well.
Very good advice.
