That's a good question, Adam. Given how late this event unfolded, it raises some doubt that we will reach the 5-season threshold. We will have to see, but if it doesn't reach 5 (say, if only NDJ through FMA are below -0.5C), then it will not show up as an event on the CPC website. 

It's also worth mentioning that event classification can change when the climatology base periods get updated every 5 years. Currently we use the 1991-2020 base period to define ONI, but soon that will change to 1996-2025, and so some of the recent ONI values will shift slightly. Sometimes those slight shifts can move an event in or out of the 5-season threshold.
