The residents of Metro Manila are being cautioned about intensifying temperatures in the region, which may reach 39°C to 41°C in the coming days. 

On Monday (May 17), the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) announced that temperature in the Greater Manila area could escalate to the ‘exreme caution’ level. 

“Sa Metro Manila, from 39 to 41 degrees Celsius ang possible heat index values in the next 3 to 4 days,” PAGASA weather forecaster Chris Perez told Inquirer

According to the weather monitoring agency, the heat index is a “human discomfort index that gives the ‘apparent’ temperature or what humans perceive or feel as the temperature affecting their body.”

PAG-ASA is urging the public to stay indoors as much as possible and to stay hydrated at all times.

“As much as possible kung walang importanteng gagawin sa labas, manatili lang sa loob ng bahay,” Perez told ABS-CBN’s Teleradyo.

Meanwhile, for those who need to go out – staying under shaded and cool places is ideal. 

“Yung mga kasama nating di maiwasang nasa labas because of the nature of their work, as much as possible sumilong at uminom ng tubig to keep themselves hydrated,” Perez recommended. 

Apart from this, PAGASA also advised people to divide meals into smaller portions throughout the day and to avoid high-protein food, which increases metabolic rate and raises body temperature.

Although hot weather is felt all over the country, Perez said isolated rains and thunderstorms caused by easterlies or warm winds from the Pacific Ocean may persist, especially in the afternoon or evening. 

Pangasinan’s Dagupan City logged the year’s record-high 53°C heat index last May 14. On Sunday (May 16), it recorded another heat index high of 49°C.
