General Flood Advisory
A general flood advisory has been issued at 6 AM on May 18, 2024, particularly highlighting the Cordillera Administrative Region (CAR). The advisory, labeled GFA#8, serves as a precautionary measure due to the increased likelihood of flooding in this mountainous area, which can be exacerbated by the ongoing weather conditions.
Detailed Advisory for CAR (Cordillera Administrative Region)
Residents and local authorities in the Cordillera Administrative Region are urged to stay alert and take necessary precautions against potential flooding. Given the region’s topography, heavy rainfall can quickly lead to river swelling and landslides. Continuous monitoring of weather updates and adhering to local advisories are crucial for ensuring safety.
Recommendations for the Public
- Stay Informed: Keep updated with the latest weather reports and advisories issued by the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).
- Prepare for Emergencies: In areas prone to flooding or landslides, ensure that emergency kits are ready and evacuation plans are in place.
- Avoid Risky Areas: During heavy rainfall or thunderstorms, avoid low-lying and mountainous regions, as well as riversides which are more susceptible to flash floods and landslides.
- Safety Measures for Mariners: For those in coastal areas, stay updated on the latest sea condition forecasts, and avoid venturing out to sea if rough conditions are expected.
By taking these precautions, residents across the affected areas can mitigate the risks posed by the current weather patterns and ensure their safety during this period of instability.
