The June/July value of the Multivariate ENSO Index (MEI) was 0.845; which was about the same value as for May/June. According to Dr. Klaus Walter this ranks as the 13th strongest "El Niño" for May/June since 1950, and is a somewhat lower value than anticipated. A tabulation of several ENSO forecasts by Australia's Bureau of Meteorology National Climate Centre suggests that a warm ENSO state is probable this Winter. Generally, warm ENSO events are associated with above average rainfall in Southern California. For example see SOI - Precipitation Scatter Plots - South Coast California Climate Division (6).
