Not by the ONI definition (in the post WWII era, at least).
Though 91/92 - 94/95 and 2002/03 - 04/05 were almost exclusively niño flavored in the grand scheme of things.
And 2014/15 - 16/17 all had niño conditions present at some point during boreal winter. Though there was a weak niña anomaly present in summer/fall 2016, which subsequently collapsed in Jan 2017.
00z EPS is legit. I can still see a pathway to cold neutral or weak niña outcome, but those odds are decreasing.
I miss ENSO neutral winters. We are owed a 3-year El Niño after 5 Niñas in 8 years.
