In neighbouring Kanniyakumari district, continuous rainfall over the last four days had resulted in many dams getting steady inflow.

Courtallam out of bounds

Following the rains, major waterfalls including Courtallam (Main falls, Five Falls) in Tenkasi district and Chinna Suruli in Theni district, among others experienced flash floods.

As the State government has not yet permitted tourists inside these falls due to the prevailing COVID-19 pandemic, the locations wore a deserted look. As a precautionary measure, police and Forest Department personnel were on duty.

A senior Forest official in the southern districts said that the Department has deployed more staff members in the waterfalls situated in forest areas cautioning visitors not to step in.
