Officials warn of heavy rains and landslides as Bay of Bengal disturbance develops

A developing low-pressure system in the Bay of Bengal will bring increased rainfall across Sri Lanka from 14 to 16 November, Meteorology Department Director of Forecasting Merril Mendis announced on 11 November.
The system is expected to move north towards Andhra Pradesh with low probability of direct landfall, but heavy thundershowers exceeding 100 mm are forecast through 13 November in several provinces and the Galle and Matara districts.
National Building Research Organisation Senior Scientist Dr. Wasantha Senadeera said landslide warnings were issued for 52 Divisional Secretariat divisions, noting heightened risk in Kadugannawa following a recent rockfall on the Colombo-Kandy road.
Officials also reported drownings in Colombo, Gampaha, Hambantota, and Matara, while two families were displaced in Kilinochchi. Naval and fishing communities off northern and eastern coasts were advised to remain vigilant.
