Heavy rains triggered a landslide blocking a mountain road as the Philippines approaches its rainy season.

Dramatic footage shows rocks and soil tumbling down the mountain slopes onto Kennon Road in Benguet province during a storm on May 31 morning.

The rockslide clogged the path and fell on a portion of a retaining wall under construction.

Authorities advised motorists to take alternate routes while the road is being cleared.

A section of Kennon Road was also temporarily closed last May 10 after it was struck by another rain-triggered landslide.

The Philippines and neighbouring countries in Southeast Asia are approaching their annual monsoon rainy season which sees soaring temperatures followed by powerful rain storms in the afternoon leading to widespread flash floods.
