Warm, Humid Weather to Continue — PAGASA

(PNA) — Except for isolated rainshowers in the afternoon or evening due to localized thunderstorms, most parts of the country will continue to experience warm and humid weather on Wednesday due to the effects of the ridge of high pressure area (HPA), according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).

PAGASA weather forecaster Jun Galang said HPA remains the dominant weather system affecting the country this time of the year.

He said despite a warmer weather, the occurrence of isolated rains will still prevail due to localized thunderstorms expected mostly in the afternoon or evening.

He explained that the convective activity brought about by intense heat triggers the formation of more cumulonimbus clouds or dark clouds associated with thunderstorms that bring rains.

The HPA which is the opposite of the low pressure area (LPA), is associated with light winds, less rainclouds, and drier air.

He said residents of places directly hit by the heat of the sun, without trees, and surrounded by concrete roads would feel much hotter.

Galang said the country will remain storm free in the next two to three days as no weather disturbance seen near the Philippine Area of Responsibility (PAR).

For Wednesday’s weather forecast, PAGASA said partly cloudy to cloudy skies with isolated thunderstorms will be experienced over the whole country mostly in the afternoon or evening.

Light to moderate winds blowing from the southeast to south will prevail throughout the archipelago and its coastal waters will be slight to moderate.

On Tuesday, Metro Manila had its highest 35.5 degrees Celsius temperature recorded at around 2 p.m. at the agency’s Science Garden in Diliman, Quezon City.

The temperature on Tuesday in Metro Manila will range 25-36 degrees Celsius while the heat index will be 28-39 degrees Celsius.

The heat index is the human discomfort index that gives the “apparent” temperature or what humans perceive or feel as the temperature affecting their body. High air temperatures and high relative humidity will give high apparent temperatures or indices. Full exposure to sunshine can increase the heat index by 9°C. (PNA) JBP/CLTC
