The intertropical convergence zone (ITCZ) will continue to affect Mimaropa, Visayas, and Mindanao, while the easterlies will prevail over Metro Manila and the rest of the country in the next 24 hours, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said on Monday, May 10.

Scattered rain showers and thunderstorms may affect Oriental Mindoro, Occidental Mindoro, Marinduque, Romblon, Palawan, Visayas, and Mindanao due to the prevalence of the ITCZ.

PAGASA advised those in these areas to remain alert against possible flash floods or landslides during moderate to at times heavy rains.


Meanwhile, Metro Manila and the rest of the country will have “fair weather” with partly cloudy to cloudy skies in the morning and isolated rain showers in the afternoon or evening.

Due to the easterlies, most parts of the country will continue to experience warm and humid weather conditions in the next few days.

Based on its extended weather outlook for key areas from May 11 to 14, PAGASA said that maximum air temperatures may reach 34-35 degrees Celsius in Metro Manila, 36-37 degrees Celsius in Tuguegarao City, 27 degrees Celsius in Baguio City, 31-32 degrees Celsius in Tagaytay City, 32-33 degrees Celsius in Puerto Princesa City, 31-32 degrees Celsius in Metro Cebu, 32-33 degrees Celsius in Metro Davao, and 32-35 degrees Celsius in Zamboanga City.

The highest recorded air temperature in the Philippines was 42.2 degrees Celsius in Tuguegarao, Cagayan on May 11, 1969.

Meanwhile, the highest recorded air temperature in Metro Manila was 38.5 degrees Celsius on May 14, 1987.

Air temperature is different from heat index as the latter is the measurement of how hot it really feels when relative humidity is factored in with the actual air temperature.

It is at least 3 degrees Celsius to 4 degrees Celsius higher than the actual air temperature.

The highest heat index so far in 2021 was recorded in Dagupan City, Pangasinan on May 8 at 51℃.
