I was kind of doubting an official Niña for awhile but the recent cooling and projected cooling/EWBs in region 3.4 coming up, along with the rapidly developing -PMM, -IOD, severely -PDO, the SOI finally going positive (albeit weakly), the MEI coupling and the continued Niña background forcing state (OLR), gives me confidence that we do see an official weak La Niña (ONI)
