The United States’ National Oceanic and Atmospheric Administration has officially issued an El Nino advisory, saying that the climate pattern has taken effect but is likely to remain weak.
“El Nino conditions across the equatorial Pacific have come together, and we can now announce its arrival,” said Mike Halpert, deputy director, NOAA’s Climate Prediction Center, and ENSO forecaster.
“While sea surface temperatures are above average, current observations and climate models indicate that this El Nino will be weak, meaning we do not expect significant global impacts through the remainder of winter and into the spring.”
NOAA’s forecasters estimate a 55 percent chance that El Nino will remain throughout the Southern Hemisphere’s Autumn.
The forecast comes after the most recent La Nina event took effect in October 20017, which lasted through to April last year before returning to neutral conditions.
