A slow moving cold front moved through the San Francisco Bay Area and Monterey Bay Area on Thursday, December 15, 2016. The front moved through the area slowly, producing moderate to locally heavy rain for several hours which resulted in nuerous reports of flooding, especially for the Northern San Francisco Bay Area. Also, this storm system produced locally strong winds with gusts greater than 50 mph. These winds brough down drought-stressed trees which damaged power lines and cares.
