Disaster management officials have placed emergency response teams on standby as enhanced Southwest Monsoon rains bring moderate to heavy rainfall across the Ilocos Region this week, the PIA reports.

While Tropical Depression Luis is expected to exit the Philippine Area of Responsibility today, August 4, the Southwest Monsoon (Habagat) will continue to bring inclement weather across Ilocos Sur, La Union, and surrounding provinces. PDRRMO Ilocos Sur Head Rhon Arquelada confirmed that the disaster council raised its alert status from white to blue yesterday, August 3, to enable continuous monitoring and deployment readiness.

Arquelada noted that expected rainfall volumes could cause flooding in vulnerable communities. “PAGASA’s rainfall outlook shows that the province may receive 50 to 100 millimeters of rain, so we encourage everyone to stay alert and continue monitoring official weather updates,” Arquelada said.

Arquelada advised residents to understand the difference between official weather tools and take preventative action at home:

  • Heavy Rainfall Warnings: Provide municipal-level forecasts every three hours using Doppler radar, serving as the basis for local class suspensions and flood precautions.
  • Weather Advisories: Cover 24-hour periods to offer a broad provincial outlook.
  • Home Preparations: Cleaning drainage canals, inspecting structural safety, and trimming hazard trees before winds strengthen.

“We advise the public to inspect and secure their homes before the weather worsens by clearing drainage canals and cutting trees that may cause hazards during strong winds,” Arquelada added. “Everyone must stay indoors unless evacuation is necessary and follow local authorities’ instructions.”

To build long-term disaster readiness, the provincial government is continuing Project ‘Agsagana’, a campaign that equips local communities with evacuation protocols, distributes emergency go-bags, and provides first-aid training to schools and public offices.
