El Niño Southern Oscillation
PAGASA has been continuously monitoring the El Niño Southern Oscillation (ENSO) conditions in the tropical Pacific. The final La Niña advisory was issued last March 10, 2023 with ENSO – neutral conditions now present. However, based on recent conditions and model forecasts, El Niño will likely develop in Jul-Aug-Sept (JAS) 2023 season and may persist until 2024. With this development, the PAGASA ENSO Alert and Warning System is now raised to El Niño Watch.
