Due to sudden cloud burst over Lhonak Lake in North Sikkim, a flash flood occurred in the Teesta River in Lachen valley. Some army establishments along the valley have been affected and efforts are on to confirm details.
Release of water from the Chungthang dam led to a sudden increase in water level upto 15-20 feet high downstream.
This has led to Army vehicles parked at Bardang near Singtam getting affected. 23 personnel have been reported missing and some vehicles are reported submerged under the slush. Search operations are underway.
