Per the following NOAA weekly Nino data thru the week centered on Feb 21, 2018; the first two plots issued today by the BoM thru the week ending Feb 25, 2018 for the Nino 3.4 and IOD, indices, respectively, and the last two images issued today by NOAA showing the Upper Ocean Heat Anom and the SSTA Evolution, respectively, for the Eq. Pac.; conditions remain in a weak La Nina condition, but I would guess that there is a 50% chance that ENSO conditions could change to a neutral state by sometime in April:
