The Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) said “above normal rainfall conditions” may occur in several areas due to the possible reemergence of the La Niña weather event in late October or November.
PAGASA said in a statement today (July 16) that there is a more than 50% chance that La Niña will develop during the last quarter of the year, and may last until the first quarter of 2022.
“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 landslides over vulnerable areas, with varying magnitude,” it stated.
It added that cool El Niño Southern Oscillation (ENSO)-neutral conditions remain in the tropical Pacific.
PAGASA said it is currently monitoring the development and will be issuing regular updates. It also advised concerned agencies to take precautionary measures to mitigate its impact.
The agency announced the onset of La Niña in October 2020, and declared it over toward the end of May 2021. PAGASA’s climate monitoring and prediction section already floated last May the possibility of the reemergence of the weather event. (PAGASA)/AG- jlo
