16 Dec 2014 – Since the beginning of the month, San Francisco has recorded more than 9.14 inches (23.2 cm) of rain, says National Weather Service meteorologist Charles Bell. The previous record of 7.10 inches was set in 1889. Data go back as far as 1849.
Not only San Francisco, major cities in the Bay Area are experiencing record rainfall during the first half of December, the National Weather Service said Tuesday.
Oakland beat the previous record set in 1950, while San Jose has endured (or celebrated?) the wettest December since 1906.
More rain was expected today.
