The influence of decadal variations on seasonal evolution of ENSO is an interesting question and not one that is well understood.  A few forecasters might factor the decadal "regime" into their forecasts just slightly (by tweaking the probabilities a few percentage points here and there) but it remains an open question how much the the lower frequency decadal background state should be considered in seasonal ENSO forecasts.   Going forward, another westerly wind burst and ocean Kelvin wave could develop, but there is no clear sign of one on the horizon at this point.
