Following the IMD warning about the cyclone posing a grave danger to life and health and safety of the public, Section 144, prohibiting the assembly of more than four people, has been imposed in Puducherry, beginning Tuesday night. It will continue till the morning of November 26, Puducherry's District Magistrate informed.

Indian Navy also informed that five flood relief teams and a diving team is ready for deployment at Chennai.
"One flood relief team each on standby at Naval Detachment Nagapattinam, Rameswaram and air station INS Parundu. INS Jyoti deployed with HADR brick and diving teams along Tamil Nadu and Puducherry coast," the Indian Navy said.
RK Jenamani, senior scientist at IMD, said Nivar Cyclone is currently 50km south-west of Chennai and is moving north-westward.
"The prediction is that it is likely to move towards Tamil Nadu coast and cross close to Puducherry at around 5 pm tomorrow. It will intensify further," he added.
Puducherry has installed "Number 7 storm warning cage at the port areas" in response to the cyclonic storm, which means the port will experience severe weather from a storm of light or moderate-intensity that is expected to cross over or near the port. A disaster rescue team of 40 people have reached Puducherry with the safety equipment to deal with the storm.
