The Philippines continues to grapple with persistent rainfall as a shear line dominates weather patterns across the region. This system extends from the Philippines through Vietnam and into parts of Malaysia, triggered by the collision of a cold surge and easterly winds. The interaction has led to significant weather events, including landslides and flooding, particularly in the Bicol Region and Catanduanes.
Ongoing Heavy Rainfall and Forecast
The shear line has caused relentless rainfall across the region, with Catanduanes experiencing landslides and widespread flooding in homes. The Bicol Region, already inundated by back-to-back typhoons earlier this season, is again facing a significant weather challenge.
As this system progresses northward, conditions in southern areas, such as Samar and northern Mindanao, are expected to improve. However, heavy precipitation is forecasted to continue in Metro Manila and northeastern Luzon, with the heaviest downpours likely over Cagayan and Apayao.
Residents in flood-prone areas are urged to take precautions. Local authorities may advise evacuation for those in high-risk zones. Individuals are reminded to avoid walking or swimming in floodwaters, which often contain sewage and other hazards.
Thunderstorms in Cebu and Spring-like Patterns
The shear line has also triggered intense thunderstorms in Cebu, accompanied by vivid lightning displays. These events resemble spring storms typically seen in the United States or Japan, where colliding air masses create unstable atmospheric conditions. While the thunderstorm activity is expected to decrease in Cebu, isolated showers may persist into the week.
Tuesday’s forecast predicts scattered showers in Metro Manila and continued rainfall in northeastern Luzon. Meanwhile, Visayas is likely to see gradual improvement, with only light rainfall in southern areas.
Broader Regional Impact
The effects of the shear line extend beyond the Philippines. Malaysia has reported flooding in central regions, and southeastern Vietnam continues to deal with heavy rainfall. Even areas as far as southern India are seeing increased rain due to related easterly interactions.
The system’s influence remains active, with another wave of rain anticipated for Vietnam by midweek. Rainfall accumulations highlight the widespread nature of this weather pattern, affecting multiple nations across Southeast Asia.
Wave and Surf Conditions
For coastal enthusiasts, wave conditions are moderate across northern Luzon, with long-period swells reported from Tacloban to Siargao. While not as intense as the previous week, these conditions are still notable, especially for surfing communities.

A Glimpse at Broader Weather Trends
Elsewhere in Asia, snow-related weather patterns have tapered off in Japan due to shifting winds. Northwestern winds, crucial for coastal-effect snow, have given way to southwesterly breezes, bringing a temporary reprieve to areas recently impacted by record-breaking snowfall in Korea. Seoul, which experienced unprecedented November snowfall, is currently enjoying milder weather conditions.
As this system moves away, attention shifts to improving conditions across the Philippines. However, preparedness remains essential, especially in flood-affected regions.
Final Words
Residents across the Philippines and Southeast Asia are advised to monitor updates from local authorities and take necessary precautions. The persistence of the shear line highlights the importance of staying informed and prepared for changing weather patterns.
