The Southwest Monsoon or Habagat will continue to affect Luzon and the western section of Visayas on Sunday, bringing scattered rains and thunderstorms to several areas, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said.
PAGASA said cloudy skies with scattered rains and thunderstorms are expected over the Ilocos Region, Cordillera Administrative Region, Batanes, Cagayan, Zambales, Bataan, Nueva Ecija, Tarlac and Occidental Mindoro.
Moderate to at times heavy rains in these areas may trigger flash floods or landslides, it said.
Metro Manila, the rest of Luzon and Visayas will experience partly cloudy to cloudy skies with isolated rain showers or thunderstorms. Severe thunderstorms may also cause flash floods or landslides.
