Coastal regions of India are bracing for heavy rainfall as an upper air cyclonic circulation over the central Andaman Sea has shifted to the North Andaman Sea, according to the India Meteorological Department (IMD).

This atmospheric condition is anticipated to develop into a Low-Pressure Area over the East Central Bay of Bengal and the adjoining North Andaman Sea within the next 24 hours. The IMD stated that the system is likely to move west-northwest and intensify into a depression by the morning of October 22, eventually evolving into a cyclonic storm by October 23 over the East Central Bay of Bengal.

Following this development, the cyclone is expected to continue its northwest trajectory, reaching the northwest Bay of Bengal off the coasts of Odisha and West Bengal by the morning of October 24.

The IMD has issued weather warnings indicating that very heavy rainfall is likely in South Interior Karnataka and the Andaman & Nicobar Islands. Additionally, heavy rainfall is expected in several other regions today, including Gujarat, Konkan & Goa, Madhya Maharashtra, Coastal and North Interior Karnataka, Kerala, Tamil Nadu, Rayalaseema, and Andhra Pradesh.

On October 19, heavy rains impacted Tamil Nadu, leading to major disruptions in services due to persistent rainfall. Footage from Chennai revealed extensive waterlogging on roads, with several areas experiencing extremely heavy rain until 8:30 am on Thursday. Kathivakkam and Manali recorded 23 cm and 21 cm of rain, respectively, while Cholavaram experienced 30 cm, Red Hills 28 cm, and Avadi 25 cm.

The depression over the west-central and adjoining southwest Bay of Bengal has been moving west-northwest at a speed of 14 km per hour, having crossed the north Tamil Nadu-south Andhra Pradesh coasts between Puducherry and Nellore at around 4:30 am on Thursday.
