Tropical Storm Co-May Displaces 278,000 in the Philippines: A Wake-Up Call on Infrastructure Failures and Climate Readiness
Over 278,000 people have been displaced by Tropical Storm Co-May in the Philippines. Floods, landslides, and collapsing infrastructure expose deep systemic vulnerabilities amid worsening climate events.

A Nation Underwater: The Human Toll of Tropical Storm Co-May
Tropical Storm Co-May swept through the northern and central Philippines in late July 2025, unleashing a cascade of destruction that forced more than 278,000 people to evacuate from their homes. The storm intensified the southwest monsoon, drenching communities with relentless rains and triggering deadly landslides and flash floods.
What began as a moderate weather disturbance evolved into a major humanitarian crisis. Rivers overflowed. Hillsides collapsed. Entire barangays were submerged under chest-deep water. By the time the storm system cleared, at least 25 lives were confirmed lost, dozens more were injured, and families across Luzon were left clinging to rooftops and rescue ropes.
Yet behind the headlines lies a deeper crisis—one that speaks not only to the power of nature but to the enduring fragility of Philippine infrastructure during climate shocks.
A Disaster Foretold: Storm Progression and Ground Impact
Co-May made landfall over Pangasinan province, with wind speeds reaching 120 km/h and gusts as high as 165 km/h. Though it did not classify as a super typhoon, its combination with the seasonal southwest monsoon created intense rainfall across several regions, including Metro Manila, the Ilocos region, Cordillera Administrative Region, Central Luzon, and Calabarzon.
By the second day of landfall, landslides had already been reported in mountainous areas of Benguet, Ifugao, and Nueva Vizcaya. Major rivers like the Pampanga and Agno swelled beyond danger levels. In urban regions such as Malabon, Marikina, and Quezon City, roads turned into rivers and vehicles floated or stalled in knee- to waist-deep waters.
At the peak of the crisis, more than 800 evacuation centers were opened. Thousands of homes, many built with light materials or on unauthorized land, were destroyed or left uninhabitable. Agricultural losses mounted in lowland farmlands, especially in rice and vegetable-growing provinces like Nueva Ecija and Tarlac, further aggravating food supply concerns.
Systemic Infrastructure Collapse in the Face of Climate Pressure
Despite repeated warnings and decades of typhoon exposure, Tropical Storm Co-May made one thing disturbingly clear: large sections of Philippine infrastructure remain deeply vulnerable during climate-induced disasters.
1. Broken Drainage and Flood Management
Many areas that flooded—like Marikina, Calamba, and Valenzuela—had experienced similar crises in the past. Yet drainage systems remained outdated, clogged, or insufficient for modern rainfall volumes. Urban development had outpaced investment in underground drainage, and natural water pathways had been paved over by housing projects or malls.
2. Landslide Zones Without Reinforcement
In upland barangays, deforestation and unchecked hillside developments left entire communities exposed. Without protective walls, soil anchors, or early warning landslide sensors, entire families were buried under collapsing hills. Several fatalities occurred in informal housing settlements built on steep slopes or near riverbanks.
3. Power Grid and Communication Breakdown
In several northern provinces, power lines collapsed, plunging areas into darkness for days. Cell towers were knocked out, cutting off access to emergency hotlines. In flood-prone communities, residents had no way to receive evacuation orders in time, resulting in late rescues or tragic losses.
4. Evacuation Centers Overcrowded and Under-resourced
With over 278,000 evacuees, many shelters operated beyond capacity. Families were packed into classrooms, gyms, and covered courts with little access to clean drinking water, food, sanitation, or privacy. For elderly people and children, the risks of dehydration, infection, and trauma increased significantly.
Human Resilience Amid Chaos
Despite the shortcomings, stories of bravery and solidarity emerged. In many towns, local government workers waded through floods to assist the elderly. Coast Guard personnel used inflatable boats to rescue residents stranded on rooftops. Private citizens volunteered food, clothes, and fuel to support rescue missions.
One resident of Bulacan described how her family survived by tying themselves together with nylon rope and holding onto a water tank while currents swept through their home. Another family in Ilocos Norte dug through mud to save neighbors buried under a landslide.
These stories, however inspiring, cannot substitute for the absence of structural preparedness.
Presidential Response and Call for Action
President Ferdinand Marcos Jr. visited several evacuation sites in Rizal and Bulacan, pledging immediate assistance and promising a reevaluation of national disaster management protocols. Emergency funds were released, and several provinces declared states of calamity to unlock financial and logistical resources.
Still, the event triggered criticism from lawmakers and civil society groups who pointed to long-standing gaps in disaster planning, especially in provincial towns where local governments lack sufficient training, funding, or equipment.
Economic Aftershock
While the physical damage from Co-May is still being assessed, the economic toll is already considerable:
-
Agriculture: Early reports suggest tens of thousands of hectares of crops were submerged, delaying the next planting cycle. With rice and corn fields especially affected, food prices are expected to rise in the short term.
-
Education: Schools used as evacuation centers will remain closed indefinitely in some areas, delaying the academic calendar and impacting over 200,000 students across Luzon.
-
Small Businesses: Wet markets, sari-sari stores, and informal vendors suffered inventory losses due to flooding, with limited insurance protection or access to capital for recovery.
-
Healthcare: Local health centers are overwhelmed with cases of diarrhea, respiratory infections, and wounds from debris or flood exposure.
Climate Change and a Nation on the Frontlines
Scientists have long warned that the Philippines—situated on the typhoon belt and the Pacific Ring of Fire—is especially vulnerable to climate change. Storms like Co-May are becoming more frequent, more erratic, and more intense.
Rising sea temperatures and changing atmospheric patterns are causing typhoons to bring heavier rains and to linger longer over land. The rainy season has also grown more unpredictable, making it harder for farmers and local officials to plan ahead.
Unfortunately, the country’s adaptation infrastructure—whether in flood mapping, housing policy, or early warning systems—has not evolved at the same pace.
The Path Forward: From Recovery to Resilience
As the waters recede, rebuilding efforts must go beyond patching roofs or repairing roads. The country needs a new blueprint for climate resilience—rooted in equity, science, and proactive investment.
Key recommendations include:
-
Modernize Drainage Networks in all major cities and integrate climate models into urban planning.
-
Strengthen Geohazard Mapping to ensure that all communities understand their landslide, flood, and storm surge risk.
-
Reinforce Housing Safety Standards, especially in informal settlements, and provide relocation incentives for high-risk areas.
-
Expand Disaster Training for local government units and barangay councils to ensure faster, decentralized response.
-
Invest in Climate-Smart Agriculture, early warning technologies, and renewable energy microgrids to reduce storm disruptions.
Conclusion
Tropical Storm Co-May was not a super typhoon. Yet it displaced hundreds of thousands, killed dozens, and revealed how even a Category 1 storm can bring the nation to its knees when infrastructure fails and planning lags behind climate reality.
As recovery unfolds, the Philippines faces a stark choice: return to business as usual, or reimagine its systems to withstand a future where climate events are no longer rare, but routine.
For the sake of the 278,000 who lost homes—and the millions still vulnerable—urgent change is not optional. It’s a necessity.
