The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) on Good Friday, April 3, warned of hot and humid weather conditions across most parts of the country as easterlies continue to dominate the prevailing weather system.
In its weather forecast, PAGASA said the easterlies—warm winds originating from the Pacific Ocean—are currently affecting Central Luzon, Southern Luzon, the Visayas, and Mindanao, bringing generally fair but humid conditions.
PAGASA weather specialist Leanne Loreto explained that much of the country will continue to experience elevated temperatures and high humidity levels.
Metro Manila and most parts of the country, PAGASA said, will experience partly cloudy to cloudy skies with isolated rain showers or thunderstorms due to easterlies.
Meanwhile, several areas, including the Ilocos Region, the Cordillera Administrative Region, and Cagayan Valley, may also encounter similar conditions due to localized thunderstorms.
Loreto noted that while rainfall is possible, widespread rain is unlikely. If there are rain showers, she explained, these will be “brief and isolated.”
However, PAGASA warned that severe thunderstorms may still trigger flash floods or landslides, particularly in vulnerable areas.
PAGASA added that on April 4, rainfall chances may slightly increase in parts of Eastern Visayas, Caraga, Davao Region, and Northern Mindanao due to localized thunderstorm activity, although no major weather disturbance is expected.
Heat Index: ‘Extreme Caution’ levels
PAGASA also flagged dangerously high heat index levels, with some areas falling under the “extreme caution” category.
In its heat index monitoring as of 5 p.m. on April 2, PAGASA said the heat index may reach 36°C in Metro Manila and 41°C in Cotabato City, as well as in Dumangas, Iloilo.
PAGASA explained that the heat index reflects the combined effect of temperature and humidity, making conditions feel significantly hotter than the actual air temperature.
Loreto noted that “the higher the moisture, the hotter it will feel, or the higher the heat factor.”
PAGASA urged the public to limit outdoor activities, particularly between 10 a.m. and 3 p.m., when heat levels are at their peak.
The agency also reminded the public that prolonged exposure to high temperatures may lead to heat cramps, heat exhaustion, and other heat-related illnesses.
Residents are advised to stay hydrated and seek shaded or cooler environments to avoid heat-related risks.
