Most parts of the country will have a mixture of sunny and partly cloudy weather except for Southern Mindanao, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) on Monday.
In an interview, PAGASA weather forecaster Jori Loiz said an intertropical convergence zone (ITCZ) is affecting Southern Mindanao while a ridge of a high pressure area is affecting Luzon.
Loiz said due to ITCZ which is the breeding ground for low pressure areas (LPAs) or potential cyclones, the Soccsksargen and Zamboanga Peninsula will experience cloudy skies with light to moderate rains and thunderstorms.
He added that a cloud cluster outside the country that has a low chance to develop into a weather disturbance is being monitored.
Loiz explained that Luzon is experiencing a heat surge because of the ridge of a high pressure area. A high-pressure area brings dry and warm winds.
To avoid heat exhaustion, people should stay indoors as much as possible, Loiz said.
People are also advised to wear clothing made of light materials with light colors, to stay hydrated by drinking plenty of water and to avoid eating food high in protein, which can increase body heat.
For Monday forecast, Loiz said that Metro Manila and the rest of the country will be partly cloudy to cloudy with isolated rainshowers or thunderstorms mostly in the afternoon or evening.
In its advisory, PAGASA said that light to moderate winds blowing from the east to southeast will prevail over Luzon and coming from the east over the rest of the country.
The coastal waters throughout the archipelago will be slight to moderate. PNA
