Tail-end of the cold front, TCZ brings rains over Eastern section of Luzon, Mindanao

MANILA, May 26 — The Philippine Atmospheric Geophysical and Astronomical Services Administration (PAGASA) said that most parts of the country will continue to experience a mixture of sunny and rainy weather on Sunday.

Weather forecaster Aldczar Aurelio said that except for eastern Luzon and Mindanao, Metro Manila and the rest of the country will continue to experience sunny to partly cloudy skies with possible isolated rains in the afternoon or evening due to evaporation or localized convection.

Aurelio said that the diffused tail-end of a cold front is affecting the eastern section of Luzon, while the inter-tropical convergence zone (ITCZ) is affecting Southern Mindanao.

In its advisory, PAGASA said Cagayan Valley, Bicol Region, SOCCSKSARGEN and Zamboanga Peninsula will experience cloudy skies with light to moderate rain showers and thunderstorms.

PAGASA also said light to moderate winds from the southeast to south will prevail over Luzon and Visayas and coming from the east to northeast over Mindanao.

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

Aurelio said that Metro Manila and the rest of the country will have "partly cloudy to at times cloudy skies with isolated rainshowers or thunderstorms mostly over the western section."

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

PAGASA said in its Sunday forecast that Metro Manila may expect temperatures of 24 to 35 degrees Celsius, while Tuguegarao City may expect temperatures of 23 to 34 degrees Celsius.

Angeles and Olongapo Cities may experience temperatures of 26 to 34 degrees Celsius.

Aurelio further noted that the country is expected to be storm-free in the coming days.

He said that PAGASA is not seeing any weather disturbance near the Philippine territory that may intensify into a cyclone for the next two to three days.

The state weather bureau expects one to two storms to affect the country this month.

The country has remained storm-free since the start of the month.

Aurelio added that the weather is on the transition period and must meet the criteria to declare the onset of rainy season.

Aurelio said five PAGASA stations must record at least 25 millimeters of rainfall for five consecutive days and not less than one millimeter for three consecutive days.

He added that the southwest monsoon or “habagat” must also be the dominant wind system in the country to declare the onset of the rainy season.

Aurelio said the southwest wind has started blowing into the country, while the easterly wind or the warm air from the Pacific Ocean is already weakening.

“Since we are now in the transition period, posibleng unang linggo ng Hunyo ay mai-i-deklara na rin ang simula ng rainy season,” (… it is possible on the first week of June, we can declare the start of the rainy season), he noted. (PNA)
