Wow, you forecasted a -PNA in 23-24. Congrats on that, I think that's a really good forecast. PNA region ended up having an anomaly of +45dm for DJFM

Yea, the outlook overall was garbage, though...I misinterpreted the El Nino adjoining the west-warm pool as more of a Modoki influence, rather than MC, which is what it was. I learned so much from that bust, and from Chris.
