Initial reports suggested as many as 49 people, including 23 army personnel, went missing following a cloudburst over Lhonak Lake in north Sikkim, where flash floods were triggered in the Teesta River basin.
Several teams of the National Disaster Response Force (NDRF) were pressed in for rescue and relief operations. Most of those reported missing and injured due to the flashfloods in Sikkim were reported from Chungthang in Mangan district, and Dikchu, Singtam in Gangtok district and Rangpo in Pakyong district. An official said some 166 people were so far rescued, including the army man.
Assessing the infrastructural damage in the state, Sikkim Chief Secretary said 14 bridges collapsed, with nine of them being under Border Roads Organisation (BRO) and five others belonging to the state government.
Parts of National Highway-10, the main link between Sikkim and the rest of the country, were washed away, while a flood alert was issued for North Bengal and Bangladesh through which the Teesta River flows.
Several towns, including Dikchu, Singtam and Rangpo, located in the Teesta basin, were flooded with the upsurge in the river. A notification by the education department said that all schools located in Mangan, Gangtok, Pakyong and Namchi districts will remain closed till October 8.

On Wednesday, the National Disaster Management Authority (NDMA) said the possible cause of the flash floods in Sikkim could be a combination of excess rainfall and a Glacial Lake Outburst Flood (GLOF) event at South Lhonak Lake in North Sikkim. The NDMA also said the Himalayan ranges are host to many glacial lakes, estimated through remote sensing techniques at about 7,500 and of these, Sikkim has around 10 per cent of which nearly 25 are assessed to be at-risk.
The National Remote Sensing Centre, one of the Isro centres, also conducted a satellite-based study on the outburst of the South Lhonak lake in Sikkim by obtaining temporal satellite images (before & after) over the water body. The space agency said it will continue monitoring the lake further using the satellite data.
