At least 193 people have been confirmed dead across Sri Lanka as authorities continue to battle rising floodwaters in parts of the capital after a powerful cyclone left a trail of destruction.

Authorities warned that more rains loom on the horizon, even as rescue teams battle rising waters in parts of Colombo and search desperately for more than 200 missing people. Among them are five Navy personnel, last seen wading into surging currents to divert water from a naval sub-station in Chalai Lagoon — a mission from which they never returned.

The cyclone’s rampage has left the country’s landscape scarred and broken: over 20,000 homes flattened, 122,000 people pushed into state-run shelters, and nearly 833,000 more in urgent need of assistance. Evacuation orders are in place in some areas as water levels of the Kelani River continue to rise rapidly.
