PAGASA has been continuously monitoring the possible re-emergence of La Nińa since April 2021. La Niña is characterized by unusually cooler than average sea surface temperatures (SSTs) in the central and eastern equatorial Pacific (CEEP). Based on the current conditions and model forecasts, there is more than fifty percent (50%) chance that La Niña will develop in either late October or November 2021, which may last through the first quarter of 2022. Meanwhile, cool El Niño Southern Oscillation (ENSO) - neutral conditions are still present in the tropical Pacific.

With this development, above normal rainfall conditions are expected over some parts of the country in the coming several months. Potential adverse impacts of the developing La Niña include floods and landslide over vulnerable areas, with varying magnitude.

All concerned agencies are advised to take precautionary measures to mitigate the potential adverse impacts of the re-emerging La Niña. PAGASA will closely monitor these conditions and regular updates and advisories shall be issued as appropriate.

For more information, please call the Climate Monitoring and Prediction Section (CLIMPS), Climatology and Agrometeorology Division (CAD) at telephone number 8284-0800 local 906 or through
