It is not clear from your graph ranking April-June data that a strong reading April-June predicts a wet winter (which is what you would believe from the newspaper reports today). 1993, 1995 through 2000 were all wet years, but 1987-1992 was a drought. 1969 was wet, but 1970 was not.1983 was record wet, but 1984 was not at all...from data I have seen, a strong ENSO increases the probability of a wet winter, but also of a dry winter. We are not saved yet.
