In California, La Nina's impact was so extreme that much of the state is in or soon will be in D4 drought (the highest category). Some of us wonder if certain dynamics caused this La Nina to behave as a much stronger event than its index would have suggested. This first year La Nina with no preceding Nino and still produced a drought similar to the infamous 1975-1976 water year. In comparison, that drought occurred in a second year event antecedent to a relatively strong La Nina. You point out that second year events are associated with even stronger precipitation impacts, particularly in Northern California. The prospect of an even worse version of what happened year (if that is possible) is extremely alarming. The odds of this, as discussed in this post, make it clear that a double dip is very much in the cards. If that should come to pass, is there any reasonable hope that California may avoid this or is the correlation so strong that it is very likely? If the correlation is very strong, then the current water conservation efforts are likely insufficient.
