(UPDATED) State weather bureau PAGASA announced the end of La Niña in a press briefing on Friday.  This, as sea surface temperatures in central and equatorial Pacific have been observed to be near or within normal levels. With this, the agency&#x27;s La Niña alert has been terminated. &quot;Sa kasalukuyan ay nakita natin na nasa neutral condition na ang El Niño-Southern Oscillation (ENSO). With that... normal rainfall conditions are being expected now,&quot; PAGASA Deputy Administrator for Research and Development Dr. Marcelino Villafuerte explained.(Currently, we have observed ENSO-neutral conditions. Normal rainfall conditions are now expected in the country.)<div><a href="https://www.abs-cbn.com/news/weather-traffic/2025/3/6/cooling-la-nina-expected-to-be-short-lived-un-1017">Cooling La Nina expected to be &#x27;short-lived&#x27;: UN</a></div>El Niño-Southern Oscillation (ENSO) is a naturally occurring climate pattern manifested in shifting wind speed and direction and sea surface temperatures in central and equatorial Pacific.The prevailing ENSO-neutral conditions — the absence of El Niño and La Niña — are forecast to last through the last quarter of the year.&quot;Posible pong mag-persist yung ENSO-neutral condition [until] September-October-November 2025 season,&quot; Climate Monitoring and Prediction Section Chief Ana Liza Solis said. (ENSO-neutral conditions may persist until the September-October-November 2025 season).PAGASA said above normal rainfall in some parts of Luzon and most parts of Bicol, Eastern Visayas, and Caraga is not likely to linger.State climatologists added that in the October-December 2025 season, climate projections are currently showing equal chances of neutral and La Niña conditions. &quot;Napakalayo pa n&#x27;yan therefore napakataas ng uncertainty and we need to keep on monitoring for monthly updates,&quot; Solis said.(It is still too far out, therefore the uncertainty is very high.)The just-ended La Niña started this January and was projected to only last in the first quarter of the year.<div><a href="https://www.abs-cbn.com/news/weather-traffic/2025/1/7/la-nina-posibleng-umiral-hanggang-marso-1916">La Niña posibleng umiral hanggang Marso</a></div>La Niña usually develops during the last quarter of the year and results to above normal rainfall conditions in the Philippines, especially in the eastern sections of the country affected by the northeast monsoon, shear line, the easterlies, and weather disturbances coming from the Pacific.<div>WARM AND DRY SEASON FORECAST</div>The state weather bureau declared the start of the country&#x27;s warm and dry season on March 26.Maximum temperatures in the northern regions and lowlands of Luzon could be above or near 39 degrees Celsius in April and May while Metro Manila and Mindanao plains may hit 38 degrees Celsius in April and 37 degrees Celsius in May.Solis said the peak of the warm and dry season occurs between the second half of April and the first half of May.To support initiatives related to mitigating the impacts of heat hazards, the agency also launched a new heat index mapping and monitoring product or iHeatMap. &quot;Hindi na po sya tabulated. Meron [na] tayong mapa... Mas user-friendly sya at interactive,&quot; Impact Assessment and Applications Section Chief Jorybell Masallo said.(It&#x27;s not tabulated anymore; we instead have a user-friendly and interactive map.)<div><a href="https://www.abs-cbn.com/news/weather-traffic/2025/1/30/what-are-the-la-nina-and-el-nino-climate-phenomena-1337">What are the La Nina and El Nino climate phenomena? </a></div>Key features of iHeatMap include high resolution and gridded heat index information, color-coded alerts, hourly forecasts for improved accuracy and reliability, and user-friendly interface optimized for desktop browsing.Masallo said different stakeholders could take advantage of the new product, especially those in the energy and education sectors. &quot;Ito ay for guidance purposes at makakaasa kayo na patuloy itong iiimprove ng PAGASA para makapagbigay kami sa inyo ng mas precise at accurate na heat index forecast,&quot; she assured the public.The product, which is still in its initial launching phase, <a href="https://src.panahon.gov.ph/pubfiles/cad/iaas/ihif_new">can be accessed here</a>.
