Campus Experts Say Increased Rainfall Into New Year Could Mark End Of California Drought

California’s current La Niña period, characterized by highly unpredictable rainfall patterns, might mean the end of the statewide drought, according to UC Berkeley environmental experts. If the rainfall continues further into the new year, most, if not all, of the state will likely see the end of the drought, according to assistant professor of water and climate Ted Grantham. Grantham said there are two definitions of a drought — the traditional meteorological drought is characterized by significantly below average rainfall. Another definition, however, also considers water supply in reservoirs.
