In a recent advisory, the India Meteorological Department (IMD) has issued a warning about a developing cyclonic threat in the Southwest Bay of Bengal. The depression, steadily gaining momentum, is currently moving west-northwestwards at a speed of 9 kmph. As of 11 pm on December 1, the center of the depression is located at Latitude 10.3 N and Longitude 85.3 E, approximately 630 km east-southeast of Puducherry.
The storm`s position places it at a distance of 630 km east-southeast of Chennai, 740 km southeast of Nellore, 810 km southeast of Bapatla, and 800 km south-southeast of Machilipatnam, according to the latest IMD bulletin. The system is expected to intensify into a Deep Depression within the next 12 hours and further evolve into Cyclonic Storm `Michaung` over the Southwest Bay of Bengal by December 3.
Projections indicate that the cyclonic disturbance will shift northwestwards, reaching the vicinity of south Andhra Pradesh and adjoining north Tamil Nadu coasts by the forenoon of December 4.

At this time, the Cyclonic Storm is expected to have a maximum sustained wind speed of 80-90 kmph, with gusts reaching up to 100 kmph.
In response to the impending threat, Tamil Nadu Chief Minister MK Stalin conducted a review meeting on Friday with 12 district administration heads.
