ITCZ to bring rains over parts of PHL –PAGASA

MANILA, May 30 — A cloudy and rainy weather in many parts of the country will be experienced on Thursday due to the intertropical convergence zone (ITCZ) across Mindanao, the Philippine Atmospheric Geophysical and Astronomical Services Administration (PAGASA) reported.

Due to the ITCZ and the extended clouds, weather forecaster Alvin Pura said that Central Luzon, Metro Manila, Calabarzon, Mimaropa, Bicol Region, Visayas and Mindanao will experience cloudy skies with light to moderate rain showers and thunderstorms.

Pura said the rest of the country may expect partly cloudy to at times cloudy skies with isolated rainshowers and thunderstoms mostly over the western section.

In PAGASA's extended weather outlook, Metro Manila will experience temperatures of 24 to 33 degrees Celsius while Tuguegarao, Angeles and Olongapo Cities may expect temperatures of 23 to 35 degrees Celsius.

PAGASA added that light to moderate winds from the east to northeast will prevail over Luzon and coming from the southeast over the rest of the country.

The coastal waters throughout the archipelago will be slight to moderate.

Pura noted that the criteria for declaring the start of the wet season still have yet to be met.

“Hindi pa rin nami-meet iyong criteria para mai-declare ang pagsisimula ng panahon ng tag-ulan dahil may mga istasyon pa rin ng PAGASA ang hindi nakakaranas ng mga pag-ulan maging ang habagat o southwest monsoon hindi pa masyado nagpaparamdam,” Pura explained.

“Kung may ulan man, hindi ito dire-diretso sa loob ng limang araw. May mga araw na wala ring ulan. Dapat dire-diretso lang,” he added.

Aside from the southwest winds, Pura said the amount of rainfall in at least five weather bureau stations across the country must reach 25 millimeters in volume for three or five straight days before they can declare the onset of the wet season.

He added that another criteria is that the volume of rainfall should not be less than one millimeter for three consecutive days.

Pura said the rainy season will likely start early next month.

“Patuloy namin binabantayan iyong mga istasyon… Kapag nagtuloy-tuloy ang mga nararanasan nating pag-ulan sa iba’t-ibang parte ng bansa, posibleng mag-deklara na tayo ng start ng wet season,” he noted.

“Kung hindi man this week, siguro by mid-June mai- de-deklara na natin ang simula ng tag-ulan,” he added. (PNA)
