Typhoon Ketsana
Definition
Typhoon Ketsana, known in the Philippines as Tropical Storm Ondoy, was a catastrophic tropical cyclone of the 2009 Pacific typhoon season that devastated Luzon — most memorably Metro Manila — before striking Indochina. It was the season’s second deadliest and costliest storm, with total damage assessed at about US$1.15 billion and 921 fatalities across the affected countries.

Also Known As
Ondoy (PAGASA local name), the “Ondoy floods.” The international name Ketsana, contributed by Laos, refers to a fragrant wood.
Examples and Analogies
Ondoy is to Metro Manila what Katrina is to New Orleans — a benchmark urban disaster. It dropped roughly a month’s worth of rain on the capital in under 24 hours, the highest 24-hour rainfall total recorded there at the time, turning Marikina, Pasig, Cainta, and neighboring areas into inland lakes.
Usage Scenarios
The storm is routinely cited in flood-control planning, disaster risk reduction and management training, insurance and business-continuity discussions, and annual September commemorations. In Filipino public discourse, “Ondoy” has become shorthand for sudden, overwhelming urban flooding.
Strategies
Post-Ondoy responses include estero (creek) rehabilitation and dredging, improved flood forecasting and warning lead times, pre-emptive evacuation, and the Metro Manila Flood Management Project. At household level, the event popularized emergency go-bags, elevated wiring, and flood insurance.
Security and Safety Measures
A state of calamity was declared over Metro Manila and wide areas of Luzon, with military and civilian rescue teams deployed and evacuation centers activated. Standard safety practice during such events: avoid crossing flooded roads, guard against electrocution, boil drinking water, and monitor PAGASA bulletins.
Historical Context
Ketsana formed east of the Philippines and crossed Luzon on 26 September 2009. A week later Typhoon Parma (Pepeng) compounded the emergency in northern Luzon. Together they exposed the decay of Metro Manila’s drainage, watersheds, and informal settlement policy, and accelerated reforms later codified in the country’s disaster-risk-reduction framework.
Challenges and Controversies
Criticisms followed over the pace of rescue operations, the exposure of informal settlers along waterways, and decades of unimplemented drainage and watershed rehabilitation. The relocation and compensation of flood-zone residents remain politically contentious to the present.
