Super Typhoon Choi-Wan sits 2,580 kilometers east-northeast of Northern Luzon, casting a long weather extension over the Philippines despite staying well outside the country’s area of responsibility. While the storm itself moves toward Japan, its trough is currently triggering scattered rains and thunderstorms throughout Visayas and Mindanao.
This shift in weather patterns requires residents in the affected southern regions to remain alert for sudden flooding and potential landslides. According to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), the risks are particularly elevated during severe thunderstorm activity, where heavy downpours can turn localized weather into dangerous hazards for low-lying communities.
Weather specialist Aldczar D. Aurelio confirmed that while Choi-Wan will not enter the Philippine Area of Responsibility, its influence persists throughout the day. PAGASA reports that the typhoon will move further away, ultimately clearing the region's weather. Once the trough dissipates, the Intertropical Convergence Zone—a band of clouds caused by trade winds from both hemispheres—is expected to move in, maintaining a risk of rainfall and flooding for the Visayas and Mindanao.
In contrast to the southern rains, Luzon, including Metro Manila, Baguio, and Legazpi, is forecast to experience generally fair conditions from Monday through Wednesday. Aside from typical localized afternoon and evening thunderstorms, no major weather disturbances are anticipated in the north. PAGASA has not issued any gale warnings, though officials note that offshore thunderstorms may still cause temporary increases in wind speed and wave heights.
