Northeasterly wind flow now prevails, early sign of transition from 'habagat' to 'amihan' — PAGASA

Published Oct 7, 2025 09:53 am  |  Updated Oct 7, 2025 01:01 pm
The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said Monday, Oct. 6, that the northeasterly wind flow is currently prevailing over parts of the country, which brings slightly cooler air and serves as an early signal that the country is moving toward the transition period from the southwest monsoon (habagat) to the northeast monsoon (amihan).
PAGASA weather specialist Obet Badrina explained that the northeasterly wind flow is a sign that the country is approaching the transition period, when wind direction gradually shifts from southwest to northeast.
He added that this shift marks the gradual end of the habagat season, characterized by warm and humid winds, and the approach of the cooler amihan season.
Over the next 24 hours, the northeasterly wind flow may bring cloudy skies with rains over Bicol Region and Quezon province, while Cagayan Valley, Ilocos Norte, Apayao, and Aurora partly cloudy to cloudy skies with isolated light rains.
ITCZ to bring scattered rains, thunderstorms
Cloudy skies with scattered rains and thunderstorms may also prevail over Palawan, Visayas, and most parts of Mindanao from Wednesday to Thursday, Oct. 8 to 9, due to the Intertropical Convergence Zone (ITCZ).
The ITCZ forms where northern and southern hemisphere winds converge, producing rain clouds and thunderstorms.
It may continue to bring light to moderate rains over Palawan from Friday to Saturday, Oct. 10 to Oct. 11.
Meanwhile, the rest of the country will have generally fair weather apart from isolated rain showers or localized thunderstorms in the afternoon or evening.
PAGASA advised the public to remain alert for possible flash floods or landslides, particularly during moderate to heavy rainfall or severe thunderstorms.
‘Halong’, LPA pose no threat to PH
Badrina also said that a typhoon with the international name “Halong” remains far from the country and is unlikely to enter the Philippine Area of Responsibility (PAR).
It was last spotted 1,875 kilometers east-northeast of extreme Northern Luzon.
Halong is also not expected to have a direct impact on any part of the Philippines.
PAGASA also monitored a low-pressure area (LPA), south of Halong, which formed 2,285 kilometers east of Eastern Visayas.
Badrina said the weather disturbance may develop into a tropical cyclone but is expected to move north-northwest and dissipate near Halong’s circulation.
