The South west monsoon and activation of a depression which was later developed to tropical cyclone “Tauktae” over the south-east Arabian sea triggered heavy rainfall in Sri Lanka from 12th to 14th May 2021. Western, South and Sabaragamuawa provinces of Sri Lanka were worst affected. Sri Lanka’s Department of Meteorology has reported a maximum rainfall up to 336 millimeters in the Western province particularly in Kalutara district. During this period four deaths have been reported in Gampaha, Colombo & Kegalle districts. Even though rain has stopped, the affected low lying areas are still inundated with floods in the nine districts and have caused damages to residential areas. Agricultural lands and standing crops have also been inundated and damaged as well as the infrastructures. Sri Lanka Metrological department predicts heavy rainfall on 22nd to 25th May and the possibility of continuation of flooding, which may increase the impact and further exacerbate the situation with further reduction of coping capacity of vulnerable households in the affected areas.
