My early thoughts for ENSO analogs for 2024-2025 are based on a combination on historical precedence of similar enso analogs to this year and long range guidance. Right now, I like 73-74, 10-11 and 88-89. 73-74 and 10-11 are La Niña winters following strong or super ninos, and are only a couple years removed from the end of a multi year nina event. Now there is still the spring predictability barrier being an issue, so it is possible that the models are incorrect about the development of La nina.
However, given the -PDO, collapse of the subsurface warmth and historical precedence following a nino this strong, I am favoring the development of La Niña in the May-June timeframe. If this turns out to be correct, I would expect the La Niña to strengthen from weak (-0.5 to -1 ONI) to strong (< -1.5 ONI) by fall. There is some guidance that keeps the La Niña as a weak event, but I am highly skeptical of that.
