The Intertropical Convergence Zone (ITCZ), or the converging of winds coming from the northeast and southeast which triggers thunderstorms and rain showers, will continue to affect most parts of the country today, the state weather bureau said.
In its latest weather update issued on Friday, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said cloudy skies with scattered rainshowers and thunderstorm will prevail over MIMAROPA, Visayas, and Caraga due to the ITCZ.
PAGASA warned residents on areas affected by the rain-induced weather system on possible flash floods or landslides during severe thunderstorms.
Meanwhile, localized thunderstorms will affect Metro Manila and the rest of the country, bringing partly cloudy to cloudy skies with isolated rainshowers.
Flash floods or landslides are also possible in areas affected by localized thunderstorms during severe thunderstorms, PAGASA added.
The weather agency earlier said that two to four tropical cyclones may enter the Philippine area of responsibility this month but they are not expected to directly affect the country.
Last week, Tropical Depression "Carina" entered the Philippine area of responsibility, the first tropical cyclone that hit the country this July and the third for 2020 after Typhoon Ambo (Vongfong) in May and Tropical Storm Butchoy (Nuri) in June.
Based on historical records, PAGASA said an average of 20 tropical cyclones is expected to enter PAR each year.
PAGASA announced last month the onset of the rainy season in the country.
