Severe disruptions from Cyclone Ditwah in Sri Lanka

Cyclone Ditwah Sri Lanka

Cyclone Ditwah, which formed in the Bay of Bengal, triggered widespread floods and landslides across Sri Lanka in late November. At least 464 people have been killed in the disaster. A further 1.4 million people have been affected in what is one of the worst natural disasters to hit the country in decades. Some of the worst-hit districts include Badulla, in Uva Province, and Kandy, Nuwara Eliya and Matale, in Central Province, where food supplies and essential utilities remain disrupted.

What to Expect:

Major disruptions to travel and services were forecast to continue for many weeks after the passage of the cyclone. Floodwaters take time to recede and authorities continue clearing mudslide debris. Thousands of people have already been evacuated. Renewed floods and landslides remain possible due to heavy rainfall during the Northeast Monsoon season, which lasts until February 2026.

Travel

Impact on Travel:

Cyclone Ditwah triggered heavy disruptions to all kinds of travel and essential services in the country. Flights were delayed, diverted or cancelled through Colombo (CMB/VCBI) and Jaffna (JAF/VCCJ) airports. Train services were cancelled across all lines at the peak of the cyclone. Railways and other public transport services were slowly resuming operations as of early December. Roads were impassable in multiple areas. Hundreds of houses and other structures were damaged. Colombo’s water supply was also at risk as flooding of the Kelani River threatened the Ambatale Water Plant.

Advice:

  • Confirm the viability of overland travel routes before departure.
  • Follow local alerts and evacuation information.
  • Immediately evacuate vehicles to higher ground if caught in rising water.
  • Remain alert for landslide warning signs, including cracks or bulges in the soil, or the faint rumbling sounds of an approaching debris flow.
  • Implement enhanced personal hygiene and sanitation practices.
  • Seek medical assistance if you develop symptoms of acute diarrhoea.
  • To minimise the risk of contracting mosquito-borne diseases, take measures to prevent mosquito bites and use insect repellents at all times.
