MANILA—State weather bureau PAGASA said rainy weather is expected to prevail across the country Thursday due to the enhanced southwest monsoon or habagat.
Weather specialist Ariel Rojas said typhoon Hanna and a low-pressure area (LPA) are strengthening the habagat.
As of 4 a.m. Thursday, the typhoon was located 485 kilometers east-northeast of Basco Batanes.
As it moves northwest, Hanna further intensified and currently packs maximum sustained winds of 175 kilometers per hour (kph), with gusts of up to 215 kph.
Tropical cyclone warning signal no. 1 remains hoisted over Batanes and the Babuyan Group of Islands.
Meanwhile, the LPA was spotted 270 kilometers west of Dagupan, Pangasinan. It is unlikely to develop into a tropical cyclone and hit land, Rojas said.
The outer rainbands of Hanna will bring light to moderate with at times heavy rains over Batanes, Babuyan Group of Islands, Ilocos Region, Cordillera Administrative Region and Cagayan Valley.
Monsoon rains are expected over Mimaropa, Zambales, Bataan, Cavite and Batangas.
Metro Manila, Western Visayas, the rest of Luzon, the Visayas and Mindanao will have cloudy skies with rain showers and thunderstorms.
PAGASA warned residents at risk of landslides and floods to take precautionary measures, coordinate with their respective local government units and monitor for updates.
Bad weather forced the cancellation of classes in several provinces.
Hanna is expected to leave the Philippine area of responsibility on Friday.
