One change I will make next season is to incorporate in season ENSO checks...I do it obsessively all fall, and then just abandon it once I issue the outlook. I am going to keep checking it at least into January...beyond that, it doesn't matter as much due to lag.
This la nina rapidly evolved into a modoki after having started east-based. Had I not been irresponsibly neglecting ENSO, I would have adjusted faster in season.
