Pedestrians walk along a street in Los Angeles, Tuesday, Dec. 22, 2015. The rain forecast in the Southland this week is the product of a series of storms forecast to cross California as a result of ``a moist northern flow pattern across the region,'' with the highest chance of precipitation today expected in the San Gabriel Mountains in Los Angeles and Ventura counties and in an area stretching from Santa Barbara northward, according to the National Weather Service.(Photo by Ringo Chiu/PHOTOFORMULA.com)
