Continuous rains from Typhoon Paolo caused the collapse of a portion of a riprap beside a house in Sitio Oit, Barangay Sta. Fe, San Marcelino town, on Friday.
The San Marcelino Public Information Office reported that no one was injured, but large rocks and mud spilled onto the road, rendering it impassable.
The Municipal Engineering Office immediately deployed a backhoe to assist in clearing operations.
The Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa) said Paolo intensified into a typhoon as it made landfall in Dinapigue, Isabela.
Since Friday morning, nonstop rains have drenched the whole of Zambales and nearby Olongapo City, prompting the issuance of an orange rainfall warning.
An orange warning is raised in areas where intense rainfall-typically 15 to 30 millimeters per hour-is observed or expected to persist for at least two hours./coa
