Warm, Humid Weather to Persist, Isolated Thunderstorms Possible

(PNA) — Warm and humid weather conditions with chances of isolated rainshowers or thunderstorms mostly in the afternoon or evening will prevail over the country on Monday, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).

In its advisory, PAGASA said that presence of the ridge of high pressure area (HPA) continues to be the dominant weather system affecting Luzon.

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

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

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

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

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

Light to moderate winds coming from the east to southeast will prevail over the whole country. The coastal waters throughout the archipelago will be slight to moderate.

On Sunday, Metro Manila had its highest temperature at 33.5 degrees Celsius recorded at around 3 p.m. at the agency’s Science Garden in Diliman, Quezon City.

The temperature on Monday in Metro Manila will range 24-35 degrees Celsius while the heat index will be 29-39 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
