Barely had residents in Davao City recovered from flash floods that killed at least 30 people when heavy rain Friday night triggered a landslide that threatened at least 20 families.

The families were brought to an evacuation center in the Matina Crossing area, radio dzBB's Davao affiliate reported early Saturday.

Continuous rain also caused floods near the boundary of Davao City and Davao del Norte, prompting families there to prepare to evacuate, the report added.

The National Disaster Risk Reduction and Management Council (NDRRMC) said the death toll from the flash floods that hit Davao City has risen to 30 as of Friday night.

In its 6 p.m. Friday update, the NDRRMC identified the latest fatality as Zaldy Supa, 34, of Arroyo Compound in Matina Crossing.

At least one person - Mark Louie Falomar, three months old, also of Arroyo Compound - remains missing.

The NDRRMC also said the floods affected some 13,746 families in Talomo Proper, Matina Crossing, Ma-a, Matina Pangi, and Matina Aplaya villages.

It said at least 137 houses were destroyed while 268 were damaged by the floods.

At the height of the flooding, the NDRRMC said evacuees sought shelter at five evacuation centers.

The NDRRMC said the Department of Social Welfare and Development provided food packs to the victims and deployed social workers to evacuation centers and funeral parlors for critical incident stress debriefing.
