latest Update Flood in North Sikkim:Deadly Cloudburst Triggers Flash Flood in North Sikkim

A cloudburst over Lhonak Lake in north Sikkim on Wednesday led to a flash flood in the Teesta River basin, resulting in the tragic loss of at least 14 lives. Among those affected, 80 individuals, including 22 army personnel, are currently missing.

The deceased, all identified as civilians, include three individuals whose bodies were discovered in north Bengal. Additionally, one of the 23 missing army personnel was successfully rescued later in the day.

The flood, which commenced around 1:30 am, was exacerbated by the release of water from the Chungthang dam, according to officials. Sikkim Chief Secretary V B Pathak reported that over 3,000 tourists from various parts of the country are stranded in different areas of Sikkim.

Nearly 65% of Sikkim’s Lhonak Lake – around 105 hectares – has been drained after a cloudburst forced the water body to overflow and trigger flash floods in the Teesta River. Temporal satellite images (referring to before-and-after) released Wednesday evening by space agency ISRO show dramatic changes in the volume of water in the lake; photos taken on September 17 and September 28 show the bullet-shaped lake holding 162.7 and 167.4 hectares, respectively.
