MANILA, Philippines – Inanunsyo ng PAGASA ang tsansa ng mas mataas sa normal na dami ng mga pag-ulan mula Oktubre 2025 hanggang Pebrero 2026 lalo na sa silangang bahagi ng bansa dahil sa mas tumaas na tsansa ng tropical cyclone activity sa Philippine Area of Responsibility (PAR).
Ito rin ay dahil sa kombinasyon ng iba’t ibang weather systems at ang La Niña conditions sa tropical Pacific area.
“Periods of cooler than average sea surface temperatures (SSTs) in the equatorial Pacific Ocean that started in August 2025 continue to persist and further strengthened reaching La Niña conditions threshold of -0.5°C sea surface temperature anomaly (SSTA) in September 2025, as shown by the recent oceanic and atmospheric indicators,” ayon sa PAGASA.
“La Niña condition exist if a one-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., September-October-November (SON), December-January-February (DJF)). It is likely that La Niña conditions will continue at least until DJF 2025-2026 season as suggested by several climate models,” dagdag pa.
Ayon sa PAGAS, ang La Niña conditions ay natutukoy kung ang one-month SSTA na -0.5°C o mababa pa ay nangyayari at inaasahang tatagal ng tatlo pang buwan. RNT/JGC
