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.

India Meteorological Department said the depression over Bay of Bengal is likely to intensify into a deep depression.

The deep depression is set to bring significant rainfall to coastal districts like Nagai, Karaikal, Thanjavur, Mayiladuthurai, and Ramanathapuram. These areas are likely to bear the brunt of the weather system. The storm’s proximity is expected to bring intense rainfall to the Delta region, which could result in localized flooding and waterlogging.

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.

IMD has issued a red alert for Nagapattinam, Thiruvarur and Mayiladuthurai districts and the Karaikal area on November 26, with the possibility of extremely heavy rainfall in many places across these four districts. On November 27, Mayiladuthurai, Cuddalore and the Karaikal area have been issued a red alert.

A deep depression in the southwest Bay of Bengal is forecasted to develop into a cyclone by Wednesday. It will likely move towards Tamil Nadu, while closely missing the Sri Lankan coast, according to the India Meteorological Department.

Tamil Nadu is bracing for a deep depression that could intensify into a cyclonic storm on November 27, bringing heavy to very heavy rainfall in coming days. While the NDRF, SDRF teams have been deployed in several districts,

The deep depression lay about 310 km southeast of Trincomalee, 590 km south-southeast of Nagappattinam, 710 km south-southeast of Puducherry and 800 km south-southeast of Chennai

Coastal and delta districts of Tamil Nadu are expected to experience intense rainfall over the next five days due to a deep depression moving towards Sri Lanka-Tamil Nadu coasts. Heavy rain is anticipated in various districts,

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.
