The ferocious storm also produced very strong winds across Northern California, including hurricane force wind of 78 mph near Lake Tahoe and over 100 mph in many spots in the mountains.
According to the National Weather Service, the highest gust recorded so far was 147 mph which was recorded near Lake Tahoe.
The powerful storm system is fueled by the “Pineapple Express” that is delivering a steady stream of moisture directly from Hawaii to the West Coast.
There were flash flood in several parts of the Bay Area and some parts of major highways were closed due to flooding.
