A total of 17 disaster response teams, comprising NDRF and state personnel, have been dispatched to vulnerable areas such as Chennai, Mayiladuthurai, Nagapattinam, Cuddalore and Thanjavur districts.

The India Meteorological Department has issued a red alert for rain for Mayiladuthurai, Nagapattinam and Thiruvarur districts in Tamil Nadu and Karaikal in Puducherry.

A deep depression in the Bay of Bengal is intensifying and expected to become a cyclonic storm, named Fengal, by November 27. It's currently southeast of Trincomalee, Sri Lanka, and moving towards the Tamil Nadu coast.

Moving north-northwestwards at 12 km/h, the storm system is expected to bypass Sri Lanka’s coast and approach Tamil Nadu within the next two days. However, slightly cooler sea surface temperatures closer to the coastline could weaken the system marginally before landfall.

The system is expected to develop into a cyclonic storm within 24 hours, with potential landfall along Tamil Nadu's coast by the end of the week.

The IMD warns that a deep depression over the Southwest Bay of Bengal is likely to strengthen into a cyclonic storm within 24 hours, potentially impacting Tamil Nadu's coast. Authorities urge readiness and caution as the system develops.

According to the India Meteorological Department (IMD), the depression in the southeast Bay of Bengal and the adjoining East Equatorial Indian Ocean will turn into a deep depression in the next 24 hours.

The latest bulletin from the IMD suggests that this depression is likely to intensify into a deep depression within the next 24 hours.
