ENSO Advisory
The El Nino-Southern Oscillation (ENSO) remains neutral. The waters beneath the surface are presently significantly warmer than normal, indicating the chance of El Niño forming later in the coming months has increased. Most international climate models surveyed suggest more warming is likely for tropical Pacific sea surface temperatures and reach El Niño levels in the southern hemisphere spring. Current.
