Snow and rain keep putting the hurt on California’s weakening drought, which now encompasses less than half the state for the first time in four years. This week, 53 percent of the state is out of drought and only 11 percent remains in “severe” to “extreme” conditions — with more rain and snow expected in the region today and Saturday. “Extreme” drought conditions linger in a sliver of northwest Los Angeles County and parts of Ventura and Santa Barbara counties, according to this week’s U.S. Drought Monitor.
