El Nino: Outlook 2018 - docs.wfp.org

Which regions will be impacted by a possible El Nino? Current forecasts provide a tentative sketch of a likely El Nino timing: a start towards late 2018 and petering out by mid 2019, with a peak sometime in January-February 2019. Growing seasons whose timing overlaps with the El Nino timing are more likely to display typical El Nino impacts.

EL NIÑO/SOUTHERN OSCILLATION (ENSO) DIAGNOSTIC DISCUSSION

9 May 2019 ENSO Alert System Status: El Niño Advisory Synopsis: El Niño is likely to continue through the Northern Hemisphere summer 2019 (70% chance) and fall (55-60% chance). During April, above-average sea surface temperatures (SSTs) persisted across most of the equatorial Pacific Ocean (Fig. 1), reflecting the ongoing El Niño.

Weak El Niño Results in a Positive Pacific-North American ...

2019.A weak El Niño has resulted in a positive state of the Pacific-North American Teleconnection Pattern (PNA). The image on the left is an idealized version of a positive PNA during December, January, and February while the middle image shows where the pattern set up in 2019.
