The Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) issued a flood advisory on Saturday, warning residents within the Cagayan River Basin of potential flooding due to the effects of Severe Tropical Storm “Nika.” The advisory, issued at 4:00 PM, highlights the flood risks from the river’s main stretch and its major tributaries in the coming hours.
Heavy Rainfall and Rising River Levels Expected
According to PAGASA’s hydrological bulletin, the water levels in the main Cagayan River, including tributaries such as Magat, Pinacanauan de Ilagan, and Siffu Mallig, are expected to rise gradually tonight through tomorrow morning. As of 2:00 PM on November 10, water levels remain below alert status. However, a slow increase in river flow has been observed, raising the possibility of overflow in the Upper and Middle Cagayan River areas.
The center of Severe Tropical Storm “Nika” was located approximately 425 kilometers east of Infanta, Quezon, with sustained winds of 110 km/h and gusts up to 135 km/h. Moving westward at 30 km/h, the storm is expected to bring moderate to heavy rainfall across the Cagayan River Basin over the next 24 hours, further stressing river systems and vulnerable areas.
Precautionary Measures for Affected Communities
Residents and local authorities in the areas surrounding the Upper, Middle, and Lower Cagayan River Basin are advised to prepare for possible riverside flooding, riverbank erosion, and rainwater accumulation, especially in low-lying areas with poor drainage systems. Notable areas at risk include San Agustin, Jones, Ilagan, Tuguegarao City, Peñablanca, and Tuguegarao. PAGASA urges local Disaster Risk Reduction and Management Councils (DRRMCs) to undertake preventive measures to mitigate potential impacts from landslides, flash floods, and river overflows.
PAGASA will continue to monitor the situation closely, providing updates on rainfall, water levels, and any emerging risks associated with Tropical Storm “Nika.” The agency advises the public to remain vigilant, stay informed, and follow the directives of local authorities to ensure safety.
