People knock fresh snow off tree branches after a storm brought snow to many southern California locales, near Yucaipa December 31, 2014. Two people died on a wind-beaten California island and crews rescued more than 100 drivers trapped in snow-caked mountains farther inland as winter storms chilled the western half of the United States on New Year's Eve, officials said on Wednesday.
