Sri Lanka: Floods - Operation Update Report n° 1 (DREF n° MDRLK012) Format Summary of major revisions made to emergency plan of action: Southwest monsoon rainy season continued with low rainfall since the DREF allocation without significant impact after the initial flooding on 14-16 May 2021. However, the intensity of the rainfall increased on 3-5 June with over 300mm of rain in certain areas, which caused floods and landslides again in the same districts where the current DREF operation is ongoing, as well as three adjacent districts in the western and southwestern part of the country. Affected districts include Colombo, Gampaha, Kaluthara, Rathnapura, Puttlam, Kegalle and Nuwara Eliya.
