PAGASA categorizes areas with a 42°C to 51°C heat index in the "danger" category, with a risk for heat stroke.

The heat index is the measure of the temperature that a person feels in contrast to the actual air temperature. Computed by factoring in the humidity as well as the air temperature, the heat index measures "human discomfort" and is the "apparent temperature" felt by the human body.

Earlier today, PAGASA announced the beginning of the rainy season in the Philippines. —Mariel Celine Serquiña/RF, GMA Integrated News
