Partly cloudy skies, isolated rain showers to prevail over most of PH during 'Undas' break

PAGASA sees low chance of cyclone formation throughout the week

Travelers and families planning activities during the “Undas” break—in observance of All Saints’ Day and All Souls’ Day—can expect partly cloudy skies with isolated rain showers in most of the country, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said on Tuesday, Oct. 28.
As of 3 a.m., the low-pressure area (LPA) that previously brought rains over parts of Visayas and Mindanao was spotted 275 kilometers east of Pag-asa Island, Palawan.
According to PAGASA weather specialist Obet Badrina, the weather disturbance, which is embedded within the Intertropical Convergence Zone (ITCZ), may either dissipate or exit the Philippine area of responsibility (PAR) in the coming hours.
He added that no other LPAs are currently being monitored within the PAR.
Cloudy skies with scattered rains and thunderstorms are expected over Palawan on Wednesday, Oct. 29, due to the trough or extension of the LPA.
From Thursday to Friday, Oct. 30 to 31–the eve of All Saints’ Day—the ITCZ will continue to bring cloudy skies and scattered rains over Visayas and Bicol Region.
The ITCZ is a weather system formed by the convergence of winds from the northern and southern hemispheres, which often produces thunderstorms and periods of prolonged rainfall.
By Saturday, Nov. 1, which marks All Saints’ Day, the eastern sections of Northern and Central Luzon, particularly Cagayan, Isabela, and Aurora, may experience cloudy skies with light to moderate rain showers due to the shear line.
The shear line forms when cold (northeast monsoon) and warm (easterlies) air masses collide, often resulting in rain showers.
Badrina said the chance of a tropical cyclone developing remains low until the end of the week.
Generally fair weather will prevail across most parts of the country during the forecast period, although isolated rain showers or thunderstorms may still occur, particularly in the afternoon or evening.
PAGASA advised the public to stay alert for possible flash floods and landslides, especially in areas experiencing moderate to heavy rains or severe thunderstorms.
