PAGASA declares start of La Niña, end of habagat
PAGASA declared on Friday that La Niña has begun and the southwest monsoon season is officially over.
La Niña is expected to last until the first quarter of 2022, bringing near to above normal rainfall conditions across most parts of the country from October to March.
The weather bureau noted cooling sea surface temperatures in the central and equatorial Pacific since July as evidence for La Niña's onset.
PAGASA forecasts four to six tropical cyclones entering or developing within the Philippine Area of Responsibility, with most likely making landfall and enhancing northeast monsoon conditions, potentially triggering floods and landslides in eastern sections of the country.
