But per the link below, a large portion of 30C area west of the dateline has cooled to almost normal based on 1991-2000 sea surface temps. So how much effect is it going to really have? I dunno, but it doesn't strike me as enough to overwhelm everything.
The dateline east (ENSO 4) has cooled to just 28.54C per Oisst.
