10 PH areas to see dangerous heat index up to 43C Sunday

Ten areas across the Philippines are forecasted to experience a dangerous heat index reaching up to 43°C on Sunday, according to PAGASA.

The "danger" classification for heat index ranges from 42°C to 51°C, posing increased risks of heat-related illnesses with prolonged exposure.

Laoag City, Dagupan City, and San Jose in Occidental Mindoro are predicted to have the highest heat index at 43°C.

Other locations expecting dangerous heat index levels include Bacnotan, Aparri, Tuguegarao City, Baler, Iba, Coron, and Masbate City, all at 42°C.

The heat index measures the temperature felt by the human body by considering both air temperature and relative humidity.

PAGASA warns that prolonged exposure under these conditions can lead to heat cramps, heat exhaustion, and heat stroke.

Despite the extreme heat in some areas, isolated rains are also expected due to the influence of the Intertropical Convergence Zone (ITCZ) and prevailing easterlies.

These warnings are based on PAGASA's 24-hour public weather forecast issued on Sunday morning.
