Typhoon “Quinta” lashed Luzon overnight, dumping heavy rains that caused flooding, toppling power lines, and whipping up giant waves that sank at least 30 boats off Batangas and Bataan provinces, disaster officials said on Monday.

No deaths were reported, but 12 fishermen were missing in Catanduanes province, according to the National Disaster Risk Reduction and Management Council (NDRRMC).

Seven fishermen from Tabaco City, Albay province, were also reported missing at the height of the typhoon, but six of them were later found in Virac, Catanduanes. The seventh, 50-year-old Joselito Ouapeuprecua, was still missing as of Monday afternoon.

The Philippine Coast Guard said it rescued seven of eight crew members of a yacht that capsized off Bauan town in Batangas.

Quinta (international name: Molave), packing wind speeds of 125 kilometers per hour and gusts of up to 150 kph, triggered flooding and prompted forced evacuations of tens of thousands of people in the Bicol, Calabarzon and Mimaropa regions.

As of 4 p.m. on Monday, the typhoon was located 310 km west of Calapan City, Oriental Mindoro province, moving westward at 25 kph, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa) said. It was expected to leave the Philippine territory on Tuesday morning,

Forced evacuations

Jessar Adornado, operations chief of the Office of Civil Defense (OCD) Bicol, said Quinta affected 608 villages and 213,145 families (843,508 people) in the region.

Local disaster councils on Sunday were able to evacuate 27,946 families (106,350 people). They have started sending home more than 18,000 families (64,000 people) as the weather improved on Monday, the OCD Bicol said.

In Calabarzon, the number of evacuees and affected residents rose to 2,061 families (8,141 people) across 108 villages. In Mimaropa, 762 families (2,964 people) were staying in temporary shelters.

Flooding was experienced in different parts of Oriental Mindoro province, Gov. Humerlito Dolor said.

In Pampanga province, water from the upstream of the Pampanga River worsened floods in 50 coastal villages where high tide raised water levels to 1.5 meters.

Bustos, Ipo dams

Bustos and Ipo dams in Bulacan province released water, submerging at least 21 low-lying villages in the towns of Calumpit and Hagonoy in floodwater that reached up to 1.5 meters on Sunday, officials said.

As of Monday noon, portions of 21 national roads were impassable due to road cuts, landslides, mudflows, collapsed bridges, sunken pavements, fallen trees and electrical posts, and flooding, according to the Department of Public Works and Highways (DPWH).

The NDRRMC said the 12 fishermen were reported missing in Barangay Pananaogan, Bato town; Barangay Cagdarao, Panganiban town; and Barangay Poblacion District III in Gigmoto town, all in Catanduanes.

According to the Coast Guard, the yacht, the MV Oceanic Explorer 3, sank in rough seas while anchored off Keppel shipyard in Barangay San Roque, Bauan, around 7 a.m. on Monday.

Seven of the eight crew members were rescued. They were identified as Tomas del Rosario, Jaime Mete Jr., Johnpaul Servando, Juliet Mayang, Andres Lazalita, Jove Muchillas and Archie Gallardo.

The Coast Guard Bauan substation said rescuers would continue to look for the eighth crew member, Rodolfo Sarabia.

In Bataan province, giant waves destroyed 30 motorized boats in Mariveles town. A roll-on, roll-off vessel, the MV RoRo-12, ran aground off Bonito Island in Tingloy town, Batangas.

Bustos Dam discharged water at up to 375 cubic meters per second (cms) on Saturday when its water elevation reached 17.01 meters above sea level (masl), which was near its spilling level of 17.34.

The water elevation at Ipo Dam was at 101.25 masl on Sunday, slightly above its 101-masl spilling mark, forcing dam officials to release water at 200 cms.

Both dams catch Angat Dam’s runoff rainwater and water discharges. 

Power outages

As of 4 p.m. on Monday, Quinta had rendered unavailable 13 69-kilovolt power transmission lines, one 230-kv line and two 5000-kv—mostly in Calabarzon and Bicol.

According to National Grid Corp. of the Philippines, the affected 69-kv lines are Batangas-Mabini,

Batangas-Ibaan-Rosario, Batangas-Bauan, Calaca-Balayan-Nasugbu/Calatagan, Calaca-Taal, Bay-Calamba, Pitogo-Mulanay, Naga-Libmanan, Naga-Lagonoy, Naga-Iriga, Naga-Tinambac, Tiwi-Malinao-Tabaco, and Daraga-Sorsogon.
