As Typhoon Marce continues to affect northern regions of the Philippines, the latest forecast indicates potentially dangerous levels of accumulated rainfall over the next 24 to 48 hours. The Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) has issued rainfall warnings, highlighting the heightened risk of flooding and rain-induced landslides across several provinces.
24-Hour Rainfall Forecast (Today, November 7)
- Intense to Torrential Rainfall (>200 mm): The provinces of Cagayan, Apayao, and Ilocos Norte are expected to experience the heaviest rainfall today, with accumulated totals exceeding 200 mm. These areas are on high alert for potential flash floods and landslides, particularly in locations that have already received significant rainfall in recent days.
- Heavy to Intense Rainfall (100–200 mm): Significant rainfall, ranging from 100 to 200 mm, is forecasted for Batanes, Ilocos Sur, and Abra. This level of rainfall poses a substantial risk of flooding, and residents in low-lying areas are urged to stay vigilant.
- Moderate to Heavy Rainfall (50–100 mm): Moderate rainfall levels between 50 and 100 mm are expected in Kalinga, La Union, Isabela, and Mountain Province. While the risk of flash floods is comparatively lower here, communities should remain cautious, especially in areas with a history of rain-induced landslides.
24-Hour Rainfall Forecast (Tomorrow, November 8)
- Intense to Torrential Rainfall (>200 mm): On November 8, Ilocos Norte is expected to bear the brunt of the rainfall with accumulated totals once again surpassing 200 mm. Given the potential for increased runoff, communities in this province should prepare for worsening conditions.
- Heavy to Intense Rainfall (100–200 mm): Ilocos Sur, Apayao, and the Babuyan Islands will likely experience heavy rainfall between 100 and 200 mm, maintaining a heightened risk for flash floods and landslides.
- Moderate to Heavy Rainfall (50–100 mm): Moderate to heavy rains are forecasted for Mainland Cagayan, Batanes, Kalinga, La Union, Abra, and Mountain Province. While impacts may be less severe, residents are still advised to monitor local conditions and remain alert.
Safety and Precautionary Measures
PAGASA warns that, under these conditions, areas highly susceptible to flooding and landslides, as identified in official hazard maps, face a heightened threat. Residents in vulnerable zones should take precautionary steps, secure vital belongings, and stay informed through local advisories. Local authorities may implement evacuation orders in particularly high-risk areas to ensure public safety.
