In the wake of a cyclonic storm warning over the Tamil Nadu-Puducherry coast in the next 24 hours, six teams of the National Disaster Response Force (NDRF) have been deployed in Cuddalore and Chidambaram towns for pe-positioning on Monday, news agency ANI reported.

"The Depression over southwest and adjoining southeast Bay of Bengal about 600 km south-southeast of Puducherry and 630 km south-southeast of Chennai. It is very likely to intensify into a cyclonic storm during the next 24 hours," the IMD said.

Due to well-marked low pressure over the southwest Bay of Bengal, a cyclonic storm is expected on the Tamil Nadu-Puducherry coast in the next 24 hours, the IMD had informed earlier today.

"The well-marked low pressure over southwest Bay of Bengal is very likely to intensify further into a cyclonic storm during next 24 hours and move towards Tamil Nadu-Puducherry coast. It's likely to cross between Karaikal and Mamallapuram by November 25 afternoon," said S Balachandran, IMD Chennai.

On Sunday, the IMD had said the "very severe" cyclonic storm "GATI" over the southwest Arabian Sea has moved westwards, the ANI report said.
