As expected, the latest ENSO forecast shows a marked increase of the chance of a La Nina occurring later in 2020. This is based on recent cooling of the equatorial Pacific Ocean, which is what is expected in a La Nina episode. The latest forecast now shows La Nina neck and neck with neutral conditions, with El Nino very unlikely to occur for the foreseeable future. This enhances the likelihood of an active Atlantic hurricane season, and means that the likelihood of warmer and drier conditions this coming winter also increases, especially in the southern parts of the region.
