MALASIQUI, Pangasinan – A total of 36 families in Pangasinan preemptively evacuated due to rising water levels in a river near their residences on Tuesday.

In an interview on Tuesday, Vincent Chiu, operations chief of the Provincial Disaster Risk Reduction and Management Office (PDRRMO), said 19 families are from Alaminos City and 17 from Bani town. "The families are still staying in evacuation centers," he said.

There was also reported flooding in Bolinao, Labrador, Lingayen, Pozorrubio, and Balungao towns, as well as in Dagupan City, Chiu said.

He also reported a mini-landslide in Bolinao, but all provincial and national roads in the province are passable.

"We remain under blue alert status probably until Thursday," Chiu said, adding there were no reported casualties and injuries so far.

The provincial government, he said, is now implementing localized suspension of classes and work, leaving the decision to the local government units based on the situation in their locality.

The Philippine Atmospheric, Geophysical, and Astronomical Services Administration said in a weather advisory on Tuesday morning that the heavy rainfall outlook in Pangasinan would be between 100 millimeters to 200 millimeters until Wednesday noon due to a low-pressure area (formerly tropical depression Luis) and enhanced southwest monsoon.

Meanwhile, 260 families in La Union evacuated due to the effects of the low-pressure area and southwest monsoon Tuesday.

One-hundred sixty-six families or 510 individuals are staying in evacuation centers in Bacnotan, Bangar, Naguilian, and Bagulin, while 33 families or 119 individuals are staying outside evacuation centers, based on the report of the Provincial Disaster Risk Reduction and Management Office (PDRRMO).

It added that 61 families were preemptively evacuated in Bauang and Aringay.

The PDRRMO also said flooding was reported in San Fernando City and Bauang, Naguilian, and Santo Tomas.

PDRRMO head Marc Cristopher Ortega said in a statement that they have deployed rescue teams and vehicles to evacuate stranded personnel in San Fernando City.

Fallen trees and landslides were also monitored in Naguilian, as well as a mini-landslide in San Jose Castro Road in Sudipen. As of posting time, all have been cleared and the road is now passable to all types of vehicles.

The PDRRMO reported mudslides in Barangay Narra Oeste, San Fernando City, and in Barangay Dallangayan Este, San Fernando City, particularly in Purok 6.

Thirty-four barangays experienced power interruptions in Bauang, Naguilian, and San Fernando.

On Monday night, the provincial government suspended classes at all levels, both in public and private, and work in government offices on Tuesday due to an orange rainfall warning (heavy to intense).

In Ilocos Sur, the Provincial Disaster Risk Reduction and Management Council raised its alert status from white to blue effective 8 a.m. on Aug. 3 to ensure continuous monitoring, preparedness, and coordination of response operations.

PDRRMO head Rhon Arquelada said the Emergency Operations Center has been activated, while its Incident Management Team, rescue personnel, and land and water search-and-rescue assets remain ready for immediate deployment.

Arquelada said PAGASA forecast 50 to 100 millimeters of rainfall in parts of Ilocos Sur and urged residents to rely only on official weather advisories from PAGASA and local authorities to avoid misinformation.

The provincial government advised residents to secure their homes by clearing drainage systems and trimming hazardous trees, stay indoors whenever possible, and immediately report emergencies to local authorities.
