Rainy season almost here

AN inter-tropical convergence zone (ITCZ) brought cloudy skies and light to moderate rains in most parts of Mindanao on Wednesday, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa).

Pagasa weather forecaster Fernando Cada said the ITCZ, a mass of thick clouds coming from south Asia, is considered a breeding ground for low-pressure areas (LPAs) or potential cyclones.

Cada added that the ITCZ induced cloudy skies with light to moderate rainshowers and thunderstorms over regions of Northern Mindanao, Autonomous Region in Muslim Mindanao, Davao, Soccsksargen and Zamboanga peninsula.

Cada noted that the rest of the country, including Metro Manila, generally had fair weather but isolated thunderstorms occurred in the afternoon or evening.


Convective activity brought about by intense heat triggers the formation of more cumulonimbus clouds or dark clouds associated with thunderstorms that bring rains.
Cada said the presence of an ITCZ signals the start of the rainy season.

He added that the ITCZ cannot move upward because of the presence of a ridge of high pressure area (HPA).

“The ITCZ usually pops out in June but the HPA is still there. We’re not experiencing the southwest monsoon or locally known as hanging habagat, which dominates our weather system during the rainy season,” Cada said in Filipino.

This year’s rainy season, he added, is expected to commence by the second or third week of June

Cada said the wind pattern prevailing in the country will be light to moderate winds blowing from the east to southeast and the coastal waters throughout the archipelago will be slight to moderate.
