EL NIÑO ADVISORY No. 9 / LA NIÑA WATCH

PAGASA has been continuously monitoring the El Niño Southern Oscillation (ENSO) in the tropical Pacific. The El Niño Advisory No. 9 was issued stating that El Nino started to weaken and may return to ENSO-neutral conditions during the April-May-June (AMJ) 2024 season. However, model forecasts suggest an increasing probability of La Niña to develop in the June-July-August (JJA) 2024 season. With this development, the PAGASA ENSO Alert and Warning System is now raised to La Niña Watch.

La Niña (cool phase of ENSO) is characterized by unusually cooler than average sea surface temperatures (SSTs) in the central and eastern equatorial Pacific (CEEP). When conditions are favorable for the development of La Niña within the next six months and the probability is 55% or more, a La Niña Watch is issued.

Pre-developing La Niña historically, is characterized by below-normal rainfall, therefore, the possibility of a slight delay on the onset of rainy season is likely with the combined effects of the ongoing El Niño.

PAGASA will continue to closely monitor the ongoing El Niño, its effect on the local climate, and the possibility of La Niña. All concerned agencies and the public are encouraged to keep on monitoring and take precautionary measures against their potential impacts.
