Authorities warn of minor flooding threat in Gin and Nilwala river valleys

The Irrigation Department issued the flood warning at 2:30 a.m. on September 24, with alerts remaining in effect until 2:30 a.m. on September 25. Residents and authorities in vulnerable areas along both river systems have been advised to exercise caution during this period.

Significant rainfall in the upper catchment areas of the Gin and Nilwala rivers has elevated water levels, prompting the department to issue precautionary warnings for communities in flood-prone zones. While authorities have characterised the expected flooding as minor, residents in low-lying settlements are being urged to remain vigilant.

The Irrigation Department typically issues such alerts to enable local authorities and communities to take preventive measures, including the movement of livestock and protection of stored crops. Residents in affected areas are advised to monitor official updates and heed any further guidance from local government bodies.
