I will also say if Nino 3.4 is at -0.1 it in no way reflects the actual picture of what is going on in the Tropical Pacific. SOI, subsurface temps, trade winds, and MEI re solidly into Nina territory right now.
This is what tropical tidbits shows. Another site I look at also looks lower than -0.1. This Nina going to end up at least -0.8 the way things look right now.
