MANILA, Philippines —  The impact of the southwest monsoon is bringing monsoon rains over the areas of Ilocos Norte, Ilocos Sur, Apayao, Abra, Batanes and Babuyan Islands, according to PAGASA.

Meanwhile, cloudy skies and scattered rain showers and thunderstorms with at times moderate to heavy rains will prevail over Metro Manila and the rest of Ilocos Region, rest of Cordillera Administrative Region, rest of Cagayan, Zambales, Bataan, Tarlac, Pampanga, Bulacan, Cavite, Batangas, and Occidental Mindoro.

The rest of the country will continue to experience cloudy to cloudy skies with isolated rain showers or thunderstorms, also due to the southwest monsoon.

The public is warned that floods and landslides may be possible especially in coastal and low lying areas due to heavy rains and severe thunderstorms.

Meanwhile, four active tropical cyclones are moving outside the Philippine Area of Responsibility (PAR).

The tropical depression formerly TD Gorio is now 760 kilometers northeast of Itbayat, Batanes.

Tropical Storm Lupit is moving 550 kilometers west northwest of Itbayat, Batanes.

Meanwhile, another tropical depression has been located at 2,095 kilometers east northeast of extreme northern Luzon while a tropical storm was spotted at 2,785 kilometers of extreme northern Luzon as well.

 

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.

Southwest monsoon affecting Luzon, ITCZ affecting Southern Mindanao

Marje Pelayo   •   September 13, 2021

MANILA, Philippines — Tropical cyclone Chantu (Typhoon Kiko) has exited the Philippine Area of Responsibility (PAR) and is now 790 kilometers North of Itbayat, Batanes.

According to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), the Southwest Monsoon and the Intertropical Convergence Zone (ITCZ) will bring cloudy skies with scattered rain showers and thunderstorms over the areas of Babuyan Islands, Batanes, Ilocos Region, Abra, Benguet, Zambales, Bataan, MIMAROPA, the Zamboanga Peninsula, and the Bangsamoro.

This may cause flash floods or landslides due to heavy to at times intense rains in the said areas.

Meanwhile, Metro Manila and the rest of the country will have partly cloudy to cloudy skies with isolated rain showers due to the combined effects of the Southwest Monsoon and localized thunderstorms.

All Tropical Cyclone Wind Signals are now lifted.

However, PAGASA said the enhanced Southwest Monsoon will bring occasional gusts reaching strong breezes to near gale strength over the coastal and upland or mountain areas of Northern Luzon, Central Luzon, Metro Manila, CALABARZON, and MIMAROPA in the next 24 hours.
