PAGASA warns 31 areas will hit danger-level heat index on Sunday

PAGASA reported that a shear line will affect extreme Northern Luzon while easterlies will impact the rest of the country on Sunday.

Batanes and Babuyan Islands are expected to experience cloudy skies with scattered rain showers and thunderstorms due to the shear line, potentially leading to flash floods or landslides.

Metro Manila and other parts of the Philippines may have partly cloudy to cloudy skies with isolated rain showers or thunderstorms in the afternoon and evening due to easterlies, posing risks for flash floods during severe storms.

PAGASA warned that 31 areas in the country will experience a heat index ranging from 42°C to 46°C on Sunday, categorized under the danger level, advising residents to take precautions against heat-related illnesses.

The heat index at Ninoy Aquino International Airport (NAIA) is expected to reach 43 degrees Celsius, with other areas such as Dagupan City and Roxas City reaching up to 46°C.

To prevent heat cramps, exhaustion, and stroke, PAGASA recommends limiting outdoor activities, staying hydrated with water, wearing protective clothing, and scheduling strenuous tasks during cooler times of the day.
