Several roads in Northern Luzon remained affected on Tuesday, August 4, 2026, as authorities continued clearing operations following the heavy rains brought by former Tropical Depression #LuisPH.

In Benguet, the Department of Public Works and Highways (DPWH) in the Cordillera region said Tawang–Ambiong Road remains temporarily closed due to a soil collapse and falling rocks.

The Gov. Bado Dangwa National Road in Poblacion, Kibungan, and another section of the same highway in Daclan, Tublay remain open to one lane only because of rockfall and collapsed stone masonry. Clearing operations are ongoing.

In Baguio City, Kennon Road remains closed to non-residents due to continuous rainfall. Motorists have been advised to use safer alternative routes such as Marcos Highway.

In Apayao, the Conner–Kabugao Road in Luttuacan, Kabugao is also limited to one lane because of a landslide, while the Apayao–Ilocos Norte Road in Poblacion, Kabugao is one-lane passable due to mudflow.

In Isabela, emergency response equipment remains on standby even though Luis has weakened into a low-pressure area.

Authorities also continue to enforce a no swimming, no sailing, no fishing policy, along with a liquor ban, because of rough seas and strong winds along the province's coastal areas.

Officials said no evacuees, injuries, or deaths have been reported in the province due to the weather disturbance.

The rainfall has also helped raise the water level at Magat Dam after months of dry weather, benefiting farmers who rely on the reservoir for irrigation.

"Ang mga pag-ulan nito ay sabihin natin na nag-increase ang elevation. However, hindi pa tayo kampante kasi baka pag-alis ng bagyo ay maranasan na naman ang continuous na walang pag-ulan," Engr. Gileu Michael Dimoloy, department head of the National Irrigation Administration–Magat River Integrated Irrigation System (NIA-MARIIS), said.

As of 10 a.m. Tuesday, the water level at Magat Dam had risen to 165.41 meters, but the NIA said it remains at a critical level.

The agency said restoring the dam's water level is important because it supplies irrigation to about 95,000 hectares of farmland cultivated by more than 62,000 farmers.

Dimoloy said cloud seeding remains one of the agency's measures to help improve the water supply.

"At least maitawid lang natin hanggang sa pag-ani ng mga farmers. Bago dumating itong bagyo ay nag-conduct tayo ng cloud seeding, and nakita naman natin 'yung epekto nito," he said.
