Heavy Rainfall Overwhelms Colombo Drainage, Flooding National Hospital
What happened
Nearly 100mm of rain fell within two hours in Colombo, overwhelming the city's drainage system which is designed to handle approximately 30mm per hour. This heavy downpour caused flooding across several parts of the city, damaging shops and roads. A section of the National Hospital was also flooded.

Why it matters
The flooding exposed vulnerabilities in Colombo's commercial capital area. The Colombo Municipal Council stated that the existing drainage capacity was insufficient to handle such heavy downpours, leading to immediate infrastructure damage and requiring planned expansion of the network.
