The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) warned that seven areas may experience a heat index ranging from 42 to 46 degrees Celsius (°C) on Friday, March 28.

A heat index between 42°C and 51°C is considered “dangerous,” as heat cramps and heat exhaustion are likely, and heatstroke may occur with prolonged exposure.

PAGASA identified the following areas that could reach dangerous heat index levels on Friday: Dagupan City, Pangasinan (46°C); General Santos City, South Cotabato (43°C); Aparri, Cagayan (42°C); Tuguegarao City, Cagayan (42°C); Cubi Pt. Subic Bay, Olongapo City, Zambales (42°C); Sangley Pt., Cavite City, Cavite (42°C); and Cuyo, Palawan (42°C).

The public is urged to stay hydrated, limit outdoor activities, and avoid prolonged sun exposure to prevent heat-related illnesses.
