MANILA, Philippines — Posibleng maranasan sa bansa ang El Niño phenomenon sa ikatlong bahagi ng taon.

Ayon kay PAGASA Forecaster Jori Lois, posibleng mas kakaunti ang mga ulan mula sa buwan ng Hulyo hanggang Setyembre.

Paliwanag nito, “Sa ngayon kasi naglalaban yung neutral condition saka El Niño. Although yung El Niño mas malaki yung percentage kesa doon sa neutral pero pwede pa mag-neutral hanggang sa buong taon.”

Noong taong 1982 – 1983 nakaranas ang bansa ng tag-tuyot kung saan naapektuhan nito ang malaking bahagi ng Luzon, Negros Occidental at Iloilo.

Umabot sa P38 million ang insurance claim sa mga napinsalang palayan at maisan habang nasa P316 million naman ang nalugi sa hydro power generation.

Noong 1986-1987, umabot naman sa P47million ang pinsala sa Luzon, Central Visayas at Western Mindanao, habang nasa P671 million ang hydro power generation loss dahil sa tagtuyot.

Halos 300-libong ektarya ng palayan at maisan naman ang naapektuhan noong 1989-1990, habang nasa P348 million naman ang nalugi sa hydro power generation.

Kinulang naman ang Metro Manila ng 20% ng supply ng tubig noong 1991-1992, habang mahigit sa 4 na bilyong piso ang naitalang pinsala sa agrikultura.

Nakaranas naman ng tagtuyot ang 70 porsyento ng bansa noong 1997-1998, at umabot sa P3 billion ang pinsala sa palay at mais maliban pa sa kakulangan ng tubig at mga sunog sa kagubatan.

Dahil dito, isa sa binabantayan ngayon ng PAGASA ang tubig sa Angat Dam.

Ayon kay PAGASA Hydrologist Richard Orendain, sa ngayon ay nasa 201 meters ang lebel nito, mababa ng walong metro kumpara noong nakaraang taon.

“Eto sa Angat lang binabanggit ko, mataas siya ng 8 meters last year. So kailangan siguro natin na umpisahan muna natin na magtipid na muna sa pagkonsumo ng tubig nang sa gayun ay umabot tayo sa pagdating ng summer.”

Pagkatapos ng isang buwan ay tinatayang bababa pa ang lebel nito sa 195.51 meters kaya’t ngayon pa lamang ay hinihikayat na ang publiko na magtipid sa tubig.

“In the coming 60 days kung talagang 0 yung rainfall natin medyo maaalangan yung supply ng tubig natin pero sa ngayon mahirap pang i-predict dahil may mga pagulan pa rin na mararanasan,” ani Orendain.

Ang Angat Dam ay pangunahing pinagkukunan ng tubig ng daang libong ektarya ng palayan sa Bulacan at mga karatig lugar.

Dito rin kinukuha ang supply ng tubig sa Metro Manila at ito rin ang nagpapatakbo sa isang hydro power plant. (Rey Pelayo / Ruth Navales, UNTV News)

Luzon placed under state of calamity

Marje Pelayo   •   November 18, 2020

MANILA, Philippines — President Rodrigo Duterte has approved the recommendation to place the entire Luzon region under state of calamity following the onslaught of consecutive typhoons.

The President announced on Tuesday evening (November 17) during his weekly public address that he signed the proclamation in response to the recommendation by the National Disaster Risk Reduction and Management Council (NDRRMC).

Based on NDRRMC’s latest report, Typhoon Ulysses caused P2.715-B worth of damage to agriculture and P5.25-B worth of damage to infrastructure.

This is on top of the total amount of damages left by previous cyclones Quinta and Rolly.

Under state of calamity, the national government and the local government units (LGUs) are given authority to use their respective funds to address the needs brought about by the calamity.

Meanwhile, the president stressed his intention to construct sturdy evacuation centers in the country following the devastation of evacuation centers from the recent cyclones.

He asked Congress to fund the construction of such structures as they serve as temporary shelter to victims of calamities and disasters.

“Iyon sana ang tugunan ng Congress kasi kapag ganitong deluge, [That’s something Congress must address because in times of a deluge] they tend to go to places for shelter and relief,” Duterte said.

“We build a strong structure, stronger than a typhoon that would come their way for people to stay. Maybe small rooms with many comfort rooms where people can really stay for a while,” he added.

To date, the NDRRMC reported a total of 73 individuals perished from Typhoon Ulysses in addition to only 25 from Super Typhoon Rolly — the strongest cyclone that hit the country this year. MNP (with reports from Rosalie Coz)

Rains increase water levels in major dams in Luzon, PAGASA says

Robie de Guzman   •   October 12, 2020

MANILA, Philippines – Water levels in dams across Luzon have increased following days of rains, the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) said Monday.

Data from PAGASA showed that as of 6 a.m. Oct. 12, the water level of Angat dam has significantly increased to 181.98 meters, which is 2.39 meters higher than the 179.59 meters recorded last Sunday.

While it is above its 180-meter minimum operating level, PAGASA said the current level is still below its 210-meter normal high water level during the rainy season.

“Ngayon ang pinakamababang bagsak ng tubig na Angat (dam)… Dapat ngayong mga panahon na ito, nasa mga 200 meters na tayo para pagdating ng Disyembre meron tayong sapat na tubig,” PAGASA Hydrologist Maximo Peralta told UNTV News in a phone interview.

Angat dam supplies water to Metro Manila and nearby provinces.

Other dams in Luzon being monitored by the bureau also saw slight increases in water levels on Monday.

Ipo dam’s water level is currently at 101.11 meters which is slightly higher than its normal high water level of 101 meters.

The management of Ipo Dam has been discharging water after the dam reached its spilling level.

La Mesa dam water level is also nearing its overflowing level of 80.15 after it rose to  79.73 meters.

Dam authorities have earlier advised areas along Tullahan river to be alert of possible flooding should the dam breach its spilling level.

Magat dam in Isabela currently has a water level of 182.20 meters, below the spilling level of 193 meters.

PAGASA said the rains in the past few days have helped boost the levels of water in dams.

The weather bureau said dam levels are expected to further rise due to rains brought about by the La Niña phenomenon that has started this October.

Around 5 to 8 more tropical cyclones are also expected to enter the Philippine area of responsibility from October this year to March next year which may also help dams in the country reach their normal high water levels. – RRD (with details from Correspondent Rey Pelayo)

Angara wants more COVID-19 mega quarantine facilities in Cebu

Robie de Guzman   •   June 30, 2020

MANILA, Philippines – Senator Sonny Angara on Tuesday called for the establishment of more mega quarantine facilities in Central Visayas, especially in Cebu as it emerges as the new epicenter of the novel coronavirus disease (COVID-19) in the country.

“The Department of Health should step up its response in Cebu City because the only way that we can flatten the curve is if all areas of the country are able to control the spread of the disease,” Angara said in a statement.

As of June 28, 2020, Region 7 has breached the 8,000 mark on the total number of confirmed COVID-19 cases, with Cebu City accounting for 4,962 of these infections.

A total of 252 COVID-19 deaths have also been recorded, with 157 of these from Cebu City.

Cebu City is the only area in the country placed under enhanced community quarantine.

The Inter-Agency Task Force for the Management of Emerging Infectious Disease (IATF) earlier said it is now looking for possible sites to construct additional isolation or quarantine facilities in Cebu City.

Angara noted that a newly-constructed quarantine facility in the city, which can accommodate more than 300 patients, was opened on Monday, June 29.

The senator, a COVID-19 survivor, also called on more hospitals in Cebu City to consider using convalescent plasma therapy to treat severe cases of coronavirus disease.

Some hospitals in Metro Manila and Cebu undertook efforts to use convalescent plasma therapy and hybrid therapeutic plasma exchange as possible treatments for COVID-19 patients.

The hybrid therapeutic plasma exchange involves the removal of bad plasma from a patient and replacing these with good plasma from donors.
