The storm dubbed the Pineapple Express by some media outlets hit wide areas of northern and central California yesterday, 11 December 2014.

US National Weather Service (NWS) say that 2.91 inches (73 mm) of rain was recorded in just one hour on the Big Sur coast yesterday. During the 24 hours of 11 December, 3.55 inches (90 mm) of rain fell in the San Francisco Bay Area. For San Francisco, it was the second wettest 11 December on record:

#SF calendar day rainfall Dec 11th was 3.40" & now 2nd wettest daily total ever for the 11th. Dec 11th '95 daily record 3.61" holds. #CAwx

Strong winds across northern California and Oregon knocked out power to tens of thousands of homes, disrupted flights and forced schools to close. One man died as a result of a falling tree in Oregon. A young boy was injured after the storm knocked down a tree near a school in city of Santa Cruz, California.

Floods and high winds caused widespread problems for roads and the transport system around San Francisco. The westbound lanes of Interstate 280 in the East Bay suburb of El Cerrito were particularly badly affected.

There have been reports of several cars becoming trapped in the floods, including 3 cars in an underpass in the Berkley area:
