MANILA, Philippines – The state weather bureau PAGASA is currently monitoring the movement of two low pressure areas (LPA) within the Philippine area of responsibility (PAR) and another outside PAR.

One is located about 195kph southwest of Sinait, Ilocos Sur which the agency expects to bring scattered rain showers and thunderstorms that may trigger floods and landslides.

The agency, meanwhile, noted that the other LPA, spotted at a distance of 335 kilometers east of Aparri, Cagayan, will not yet directly affect any part of the country.

Meanwhile, Pagasa said that the third LPA located at 1,120 kilometers east of Mindanao is also expected to enter PAR.

The weather agency clarified, however, that there is slim chance that any of the three LPAs would develop into tropical cyclone.

Despite occasional rains, there are still 17 areas across the country which are experiencing drought specifically areas in Bicol and Eastern Visayas. –Marje Pelayo (with details from Rey Pelayo)  

Scattered rains to prevail over Metro Manila, other areas due to LPA, ITCZ

Marje Pelayo   •   September 17, 2021

MANILA, Philippines — State weather bureau PAGASA forecasts scattered rains over Metro Manila and other areas due to the combined effects of the Intertropical Convergence Zone (ITCZ) and brewing low pressure area (LPA) south of the country.

Aside from Metro Manila, scattered rains will also prevail over the areas of areas in Central Luzon, CALABARZON, MIMAROPA, Western Visayas, Zamboanga Peninsula, Bangsamoro, SOCCSKSARGEN, Isabela, Quirino, Nueva Vizcaya, Benguet, Ifugao, La Union, Pangasinan, and Camarines Norte.

This, as PAGASA monitors the LPA specifically located at 90 kilometers east southeast of Romblon, Romblon, based on PAGASA’s 4:00AM forecast.

The LPA, embedded in the ITCZ generally affects Southern Luzon, Visayas, and Mindanao.

Meanwhile, the rest of the country will have isolated rains or thunderstorms due to the impact of ITCZ combined with localized thunderstorms.

These weather conditions are likely to cause flash floods or landslides due to moderate to at times heavy rains or severe thunderstorms.

Thus, residents in areas prone to these hazards are advised to take precautionary measures for possible danger.

La Niña likely in the last quarter of 2021 — PAGASA

Marje Pelayo   •   September 14, 2021

MANILA, Philippines — The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said that La Niña may occur in the coming months.

Based on the agency’s La Niña Alert issued on Tuesday (September 14), there is a 70% to 80% chance that La Niña will form in the last quarter this year.

This phenomenon may persist or prevail until the first quarter of 2022, the agency said.

Also, PAGASA’s rainfall forecast suggests that above-normal rainfall conditions in many areas may be experienced in the next several months.

This can be attributed to the expected stronger easterlies, enhanced Northeast monsoon and tropical cyclone occurrences, according to the advisory.

“The eastern sections of the country which normally receive more rainfall during the last quarter of the year could further increase the likelihood of more adverse impacts such as floods and landslides over highly vulnerable areas,” PAGASA Administrator Vic Malano said in the advisory.

“With this scenario, all concerned agencies are advised to take precautionary measures to mitigate the potential adverse impacts of this looming La Niña,” he added.

La Niña phenomenon refers to the unusually cool ocean surface temperatures in the central and eastern equatorial Pacific.

MANILA, Philippines — The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) Hydrometeorology Division advises residents in some parts of Bulacan to take caution amid the continuous spilling operations at Ipo Dam.

As of 8:00 a.m. Tuesday (September 14), the water level of Ipo Dam is 100.72 meters.

The dam management continues to conduct spilling operations with one gate open and thus, PAGASA advised residents in low-lying areas and those living near the riverbanks of Angat River from Norzagaray, Angat, San Rafael, Bustos, Baliuag, Pulilan, Plaridel, Calumpit, and Hagonoy to be alert for possible increase in water level.

PAGASA assured that it will continue to monitor the hydrological condition of Ipo Dam along with the Dam management for updates.
