The Philippine Institute of Volcanology and Seismology (Phivolcs) warned of possible lahar flows at Mayon and Kanlaon volcanoes as Tropical Storm Ada brings heavy to heavy rains over Luzon and the Visayas.
PAGASA said Ada could dump 100 to 200 millimeters of rainfall, which may trigger muddy and debris-laden flows that pose life-threatening risks to nearby communities.
At Mayon, hot and non-eruption lahars may affect several river channels in Albay, while Kanlaon, currently at Alert Level 2, is also vulnerable due to recent ash deposits and weakened slopes.
Phivolcs urged residents and local government units to closely monitor weather advisories and implement preemptive safety measures.
Meanwhile, Ada has caused major travel disruptions, stranding over 5,000 passengers at ports and forcing the cancellation of 16 domestic flights nationwide.
