November 27, Colombo (LNW): The Department of Irrigation has cautioned that severe flooding could develop within the next 24 hours in low-lying areas along the Mahaweli River, particularly within the Yatinuwara and Gangawata Korale Divisional Secretariat divisions.

A red-level warning was issued after sustained heavy rainfall was recorded across the river’s upper catchment, with gauge readings monitored by the department showing a steady rise in water levels.

Officials warned that the combination of continued rain and increasing river flow presents a significant threat to communities situated close to the riverbanks.

Residents living near the Mahaweli in the affected divisions have been urged to remain on high alert, prepare for rapid evacuation if necessary, and take all appropriate safety measures. Disaster response teams have been requested to activate precautionary plans and be ready for immediate deployment.

In a separate advisory, the department also signalled the possibility of minor flooding in the Kelani River valley, particularly in the Ruwanwella Divisional Secretariat area. An amber warning was issued after notable rainfall was observed in the upper sections of the Kelani basin early this morning. Hydrological data suggests that vulnerable low-lying zones could experience inundation within the coming day.

Authorities have called on motorists and residents in these areas to exercise extreme caution, while disaster management units have been instructed to remain prepared for any escalation in conditions.
