Here's a comparison with the WWB we saw in mid march and for same time period in 2005:

Yeah, this is finally where we diverge from that 2005 analog. I'm surprised it hung around until May. There should be some warming at least of the subsfc soon.

However, it looks like this is the peak of the WWB. Even the CFS has backed off (w/ a drop in SSTA forecast). That means that if this won't significantly boost subsfc anomalies, we'll have to wait weeks. And already, at this point, the current El Niño isn't that healthy

Looks like we have a down welling kelvin wave with the newest data

Thinking safest bet is warm neutral w/ weak El Niño close behind. Just not enough heat in the subsfc even considering the new KW, and it doesn't look like there will be another WWB until June, due to MJO

A big drop from last week +0.9C to now +0.5C in this weeks update.

Think you can blame some of the cooling on the cool area around 130°W

Looks like its due to Nino 3 tanking. That PDF has PENTAD graphics that show cooler anomalies mixing in at the surface beneath Nino 3. With Nino 4 rising looks like the Modoki signature is back.

This is interestingly similar to what we saw last year. I remember last year at this time time there was a period of relaxed trades across the CPAC/EPAC followed by a WWB in June that didnt do much but kept the status quo going. SSTs were in the +0.3C/+0.5C area until October.

Yeah, w/ the WAM waking up I think the ENSO is getting stuck in warm neutral again as the monsoon standing wave overpowers the ENSO one (this hasn't happened yet). The subsfc is cool but there is a small downwelling KW coming, which would bump Niño SSTAs up. Anyway I agree w/ you, sticking around in the warm side of warm neutral looks like a good call currently.

There's the big Pacific warm pool again which would promote an active season in the EP/CP, and the possibility of an above average Atlantic season, would be interesting if that happened again

This is really closing in on a La Nada if you ask me. I just don't think it's a serious factor for the upcoming Atlantic hurricane season. What I am watching is the anomalies in the Pacific off the immediate coast of South America, Central America and Mexico. If you see cool/neutral there, it will mean sinking air there. Which pumps rising air to the east (GOM/ATL), where it matters. If you see that you know ATL season is not going to be impeded by ENSO this year.

Cant be a La Nada since we're in a present El Nino and theoretically theres enough juice to keep ONI at El Nino threshold for the next several months. Almost setting up to be exactly like last year. Nino 1+2 was similar last year as well.

Unless we get a few more rounds of strong trades by July.

Shocking to see the Niño 3.4 cool so much during the WWB. It could be a delayed response, but so far this WWB did not do what it needed in order to kick start the Niño into steady growth. We are still in an El Niño for the time being, but with the subsurface quite cool and this downwelling KW not looking very impressive so far, ENSO dropping into warm neutral territory at some point this summer is not out of the question.

Cooling happening east of where the WWB is occurring where the trades are still running above average. The Euro forecast shows that the trades will slow down considerably for the rest of the month so we will likely see Nino 3.4 fluctuate between +0.4C/+0.8C until June.

Slow down considerably? Hasn't the WWB already peaked? It does appear that trades will be relaxed, but the peak of the WWB has already occurred.
