Summary Strong El Ni ñ o this year, but ENSO Index is not as good a • predictor of precipitation in California as thought Precipitation was above normal in December and January, but • February has been very dry Above-average precipitation in March and April is forecasted • Snow pack greatly improved from last year, but may melt • earlier than normal Surface reservoir storage is improving from the preceding dry • years, but likely will not recover fully this year Groundwater levels were significantly lowered during the • recent drought and will take several wet-normal years to recover La Ni ñ a conditions may occur next year • The effect of the drought is not over •
