The state weather bureau on Monday advised the public to bring umbrellas and raincoats as occasional rains are expected over parts of Luzon and Visayas due to southwest monsoon or “hanging habagat” as it continues to be the dominant weather system affecting the country.
The southwest monsoon, which is associated with the occurrence of intermittent to continuous rains, is the prevailing wind system during the rainy season.
In its Monday forecast, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said occasional rains will be experienced over Metro Manila, Ilocos Region, and the provinces of Mindoro, Palawan, Cavite, Laguna, Batangas, Rizal, Bataan, Pampanga and Zambales while cloudy skies with light to moderate rains and isolated thunderstorms are expected over Eastern Visayas and the rest of Luzon.
Partly cloudy to cloudy skies with isolated thunderstorms will prevail over Mindanao and the rest of Visayas.
PAGASA also said moderate to strong winds blowing from the southwest to south will prevail over Luzon and Visayas and the coastal waters along these areas will be moderate to rough.
Elsewhere, winds will be light to moderate coming from the southeast to south with slight to moderate seas.
In a weekly outlook, PAGASA noted that by Monday until Thursday (August 10-13), the concentration of maximum rainfall is expected to shift to Ilocos Region, Zambales and Bataan. These areas will have monsoon rains which may trigger flashfloods and landslides while the rest of Luzon will have cloudy skies with light to moderate rains and isolated thunderstorms while Visayas and Mindanao will have generally fair weather.
By Friday (August 14), Ilocos region will have cloudy skies with light to moderate rains and isolated thunderstorms while Metro Manila and the rest of the country will experience partly cloudy to cloudy skies with isolated thunderstorms.
