PAGASA categorizes areas with 42°C to 51°C heat index under the danger category, while areas with a heat index of 52°C and above fall under extreme danger.

PAGASA said heat cramps and heat exhaustion are likely in areas experiencing a danger level heat  index. Heat stroke is also possible with continued exposure.

The public was advised to stay hydrated, limit outdoor activity, and wear fresh clothes to avoid heat-related illnesses. —Jiselle Anne Casucian/VBL, GMA Integrated News
