<p>MANILA — The low pressure area (LPA) that used to be Tropical Depression Wilma is expected to fully dissipate within the Philippine area of responsibility, but state weather bureau PAGASA warned that rains will persist in parts of Luzon due to the combined effects of the LPA, the shear line, and the northeast monsoon, or amihan.</p><p>In its 5:00 p.m. bulletin on Monday, December 8, weather forecaster Leanne Loreto said the remnant circulation of Wilma continues to influence weather conditions over Mimaropa, though it is no longer expected to reintensify.</p><p>“Kahapon nga po ay nag-downgrade na o mas humina bilang isang low pressure area lamang iyong bagyo. Ngunit sa ngayon, nakakaapekto pa rin po ito sa bahagi ng MIMAROPA area, specifically sa may Palawan, Mindoro provinces, pati na rin po sa may Marinduque,” said Loreto.</p><div><a class="fr-green fr-strong" href="https://www.abs-cbn.com/news/weather-traffic/2025/12/8/no-storm-expected-this-week-but-amihan-shear-line-will-bring-rains-in-northern-luzon-0022">No storm expected this week, but Amihan, shear line will bring rains in Northern Luzon</a></div><p>“Sa ngayon, hindi na natin ito inaasahan na mag-develop muli bilang isang bagyo. Sa halip ay nakikita natin na ito po’y mag-dedisipate na lamang sa loob ng ating area of responsibility o malulusaw ng tuluyan,” she added.</p><p>As of Monday afternoon, the LPA was located about 200 kilometers east-southeast of Puerto Princesa City. </p><p>While weakening, it may still bring flash floods and landslides across rain-prone communities.</p><div> </div><div><strong>SHEAR LINE TO AFFECT NORTHERN AND EASTERN LUZON</strong></div><p>Beyond the LPA, Loreto said the shear line, where cold <em>amihan </em>winds meet warm easterlies, continues to trigger cloudy skies and scattered thunderstorms over large portions of Northern and Eastern Luzon.</p><p>“Ito naman pong shear line o iyong linya kung saan nagsasalubong iyong hanging amihan at iyong easterlies ay magdadala po ng makulimlim na panahon,” Loreto said.</p><p>The strongest rains are expected in Cagayan Valley and the Cordillera Administrative Region, with rainfall totals possibly reaching up to 100 millimeters by Tuesday afternoon. PAGASA warned that such volumes may lead to localized flooding and landslides.</p><div><a class="fr-green fr-strong" href="https://www.abs-cbn.com/news/weather-traffic/2025/12/8/temperature-in-parts-of-ph-expected-to-dip-to-7-9-c-in-early-2026-pagasa-1445">Temperature in parts of PH expected to dip to 7.9 °C in early 2026: PAGASA</a></div><div><br/></div><div><strong>AMIHAN BRINGING COOLER TEMPERATURES</strong></div><p>The northeast monsoon has begun to intensify, lowering temperatures, especially in the Ilocos Region, Central Luzon, and Metro Manila.</p><p>“Kaya ngayon ay nagsisimula na nga po natin maramdaman iyong simoy ng amihan o iyong simoy ng Pasko, mas bumababa na din po iyong ating mga temperature,” Loreto said.</p><p>“Specifically po dito sa may areas ng Ilocos Region and parts din po dito sa Metro Manila and the rest of Central Luzon,” she added.</p><p>Baguio City is forecast to experience temperatures as low as 13°C by Tuesday, while Metro Manila’s maximum temperatures will remain at around 30°C.</p><p>PAGASA said that based on current monitoring, no new weather disturbances are expected to form in the next one to two weeks.</p><p>“At sa next 1 to 2 weeks, so inaasahan nga po natin na wala pang mabubuo na kahit anumang sama ng panahon.
