California sees unusually high 'king tides' - Article Photos 3/12

A cyclist rides his bike through flooding at a Highway 1 off ramp from highway 101 in Marin County, Calif. Wednesday, Dec. 12, 2012. Forecasters are urging people enjoying the Northern California coast to be careful as high tides and big waves hit the region's beaches during the next few days. The National Weather Service says so-called King Tides — caused by a rather unique combination of how the sun, the moon and the earth align — will bring the highest tides of the year on Thursday, Friday and Saturday mornings.
