Following a storm system set to bring drenching rain and mountain snow to the Pacific Northwest late this week, another system will track into Southern California this weekend. The latest U.S. drought monitor from March 1 showed that nearly 20 percent of California remains in severe drought, with moderate drought gripping about 50 percent of the state. Areas from central to Southern California are being gripped by the worst of the drought, including the cities of Fresno, Los Angeles and San Diego.
