PAGASA ENSO Alert System Status

PAGASA: La Niña conditions are present in the tropical Pacific and are expected to persist through February-April 2025 season; A transition to ENSO-neutral likely during March-May 2025 season. *La Niña condition – a 1-month SSTA of -0.5°C or less is observed and an expectation that the 3-month SSTA (Oceanic Niño Index) of -0.5°C or less will be met (i.e DJF). This condition increases the likelihood of having above-normal rainfall conditions, which could lead to potential adverse impacts such as heavy rainfall, floods, flash floods, and rain-induced landslides over highly vulnerable areas.
