Discussion: After several weeks of missing data due to impacts on the NCDC located in Asheville, recovery is accelerating and availability of weekly ENSO data returns. The Nino SSTA regions are locked-in on neutral phase (Fig. 1). There is no shift in trend to indicate La Nina onset. In the subsurface, the anomalous cool water to fuel La Nina is diminishing (Fig. 2). Most of the cool water is between 100 and 150 meters with about half the strength of several weeks ago. Consequently, neutral ENSO persists and the likelihood of La Nina developing later in 2024 is diminished.
