The Northeast Monsoon officially ended over the South Peninsula on December 31, 2025, but an unseasonal weather system is set to bring fresh rainfall to the extreme south.

A depression has formed over the southeast Bay of Bengal and adjoining equatorial region under a cyclonic circulation.

Moving west-northwest, the system will approach Sri Lanka and the South Tamil Nadu coast.

While further intensification is unlikely, heavy to very heavy rain is expected over Sri Lanka, with spillover effects into Tamil Nadu.

Rainfall will increase over South Coastal Tamil Nadu from late night tomorrow, peaking between January 9 and 11. Pamban, Tuticorin, Nagercoil and Kanyakumari are at risk.

Seas will remain very rough. Conditions improve from January 12.
