Heavy rain struck Maasim town, Sarangani Province, southern Mindanao, Philippines, on October 6, causing flash floods that temporarily shut down portions of the national highway traversing the area.
At least one person was electrocuted while four others were injured during the floods, local media reported.
At around 15:00 LT (local time), floodwaters mixed with mud, logs, branches, and other debris surged across the highway in Barangay Tinago, Poblacion, after Tinago Creek overflowed, leaving the highway impassable.
Videos of the flooding went viral on social media. One video showed a man clinging to a tree in order to save himself from the flooding waters rushing past him.

According to the Municipal Disaster Risk Reduction and Management Office (MDRRMO), the creek had been partly clogged by debris from nearby slopes, worsening the overflow.
At least four barangays were damaged by the flash flooding, affecting approximately 100 families, according to the Maasim Municipal Disaster Risk Reduction and Management Office (MDRRMO). Over 20 houses were damaged or submerged, forcing residents to evacuate and seek immediate shelter.
By late evening, road-clearing operations had removed most obstructions, allowing vehicles to pass through reopened sections.
The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) attributed the rains to the Intertropical Convergence Zone (ITCZ), which continues to bring scattered and occasionally intense rainfall across parts of Mindanao.
MDRRMO stated that relief and assessment teams had been mobilized to evaluate the impacts, assist residents, and restore disrupted utilities.
The Sarangani provincial government said that it would provide assistance to affected communities. PAGASA forecasts continued light to moderate rain and a risk of localized flooding through October 7.
Road crews remain on alert for additional runoff or slope movement, and local disaster units continue to advise residents and motorists to stay vigilant during periods of heavy rain and to follow any evacuation or traffic advisories.
