Heat index in Metro Manila at extreme caution, up to 42°C

The heat index in Metro Manila on Thursday is classified as 'extreme caution' due to the influence of easterly winds, reaching up to 42 degrees Celsius at NAIA and 40 degrees Celsius at Quezon City's Science Garden.

Metro Manila and other parts of the country will experience partly cloudy to cloudy skies with isolated rain showers or thunderstorms, posing risks for flash floods or landslides during severe storms.

PAGASA warns that Batanes and Cagayan will have cloudy skies with scattered rain showers and thunderstorms due to a Frontal System, potentially leading to flash floods or landslides from moderate to heavy rains.

To prevent heat cramps, exhaustion, and stroke, PAGASA advises limiting outdoor activities, staying hydrated, avoiding alcohol and caffeine, wearing protective clothing, and scheduling strenuous tasks during cooler parts of the day.

The weather bureau forecasts light to moderate winds from an east to northeast direction for eastern Northern Luzon with slight to moderate coastal waters expected across the country.
