Fifteen locations had heat indices above the “danger” threshold on Sunday, May 7, according to the monitoring of the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).
PAGASA defines the heat index as the measurement of how hot it feels when relative humidity is factored in with the actual air temperature.
The areas with the highest heat indices observed on Sunday were Dipolog, Zamboanga del Norte (45°C); Daet, Camarines Norte (44°C); Legazpi City, Albay (44°C); Zamboanga City, Zamboanga del Sur (44°C); Aparri, Cagayan (43°C); Iba, Zambales (43°C); Infanta, Quezon (43°C); Masbate City, Masbate (43°C); Roxas City, Capiz (43°C); Catarman, Northern Samar (42°C); Dagupan City, Pangasinan (42°C); Laoag City, Ilocos Norte (42°C); Ninoy Aquino International Airport, Pasay City (42°C); San Jose, Occidental Mindoro (42°C); and Sinait, Ilocos Sur (42°C).

In the next 24 hours, PAGASA said the Kalayaan Islands will have cloudy skies with scattered rain showers and thunderstorms due to a low pressure area.
It warned of moderate to occasional heavy rains that could cause flooding or landslides in the Kalayaan Islands.
Meanwhile, the rest of the country will continue to experience partly cloudy to cloudy weather with isolated rain showers or localized thunderstorms due to the easterlies.
