PAGASA issues Undas 2026 outlook; monsoon, shear line and ITCZ to affect country through Nov. 2
Published · Updated
What happened
PAGASA published a Special Weather Outlook on October 28 covering the Undas period through November 2. The agency said the northeast monsoon, shear line, and ITCZ will influence weather conditions nationwide, and identified Batanes and Extreme Northern Luzon as areas to watch for rain during the peak travel period.
Why it matters
The weather outlook arrives before a high-mobility holiday period when ferries, flights, road travel, and cemetery visits increase. An official forecast window tied to multiple weather systems can change local government deployment, transport advisories, and relief positioning over the next 24-72 hours.
PAGASA released a Special Weather Outlook for Undas 2026 on October 28, saying the northeast monsoon, shear line, and the intertropical convergence zone will affect parts of the Philippines through November 2. The bulletin flags cloudy to rainy conditions over the holiday travel window, with Batanes expected to see isolated light rains on October 30 and rains by October 31. Coming days after recent typhoon stress in the north, the outlook puts local preparedness, transport management, and relief pre-positioning under near-term scrutiny.
