The heat index is expected to reach a dangerous level of 45°C in two areas on Saturday, April 25, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).
In its latest two-day heat index forecast, the state weather bureau said Dumangas in Iloilo and Butuan City in Agusan del Norte are likely to experience the highest temperature for the day at 45°C.
The warning comes as Iloilo continues to endure extreme heat conditions, marking its second consecutive day under the “danger” category after recording heat index levels as high as 46°C the previous day.
PAGASA also placed at least 12 areas under the “danger level,” where residents may experience heat cramps and heat exhaustion, with prolonged exposure increasing the risk of heat stroke.

The weather bureau continues to urge the public to take precautionary measures, such as limiting time under direct sunlight, staying hydrated, wearing light clothing, and seeking shaded or cooler environments to avoid heat-related health risks.
