[AbruptSLR]

I've really appreciated your Monday updates, ASLR.  (And I'll work on 'hearing'/applying your plea on another thread.)

Glad to be of service.

Time for a “2018 ENSO” thread? 

La Niña firmly in control of eastern tropical Pacific. Updated past 2+ years of Oceanic Niño Index (ONI) and IRI/CPC forecast for 2018. #LaNina

Well, La Niña should start to weaken considerably in a coupke of weeks or so. The warm pool in the West Pacific is according to Australian BOM a possible precursor to an end of the current event.

From ENSO wrap-up by January 3 at BOM:

"However, a build-up of warmer water beneath the surface of the western Pacific may be a precursor to the end of this event in the coming months."

The rest of 2018 should most likely be a neutral year or maybe with a weak El Niño depending on how quick La Niña weakens and vanish. If 2018 ends up being neutral I'm quite sure we'll see a moderate-strong El Niño emerging in 2019. And yes, that should mean that either 2019 or 2020 will have a ggod chance to end up being the warmest year on record.
