Heavy rainfall in Karnataka and Kerala has caused the Kaveri River to overflow, flooding Hogenakkal in Tamil Nadu as Kabini and KRS reservoirs release excess water. While the surge benefits irrigation at the Mettur Dam, it poses major flood risks. Meanwhile, a low-pressure system in the Bay of Bengal has triggered cyclone warnings for Tamil Nadu ports, with heavy rainfall and strong winds forecast in coastal districts. Authorities are on high alert with safety measures, flood monitoring, and disaster response teams deployed.
