Cyclonic Circulation Over North Andaman Sea Expected to Form Low-Pressure Area by October 22

The India Meteorological Department (IMD) in Amaravathi has announced that a fresh upper air cyclonic circulation is expected to form over the North Andaman Sea around October 20. According to the IMD, this system is likely to develop into a low-pressure area over the Central Bay of Bengal by October 22, after which it is expected to move northwestwards and intensify further.

The IMD also noted the persistence of a well-marked low-pressure area over south coastal Andhra Pradesh and adjoining north coastal Tamil Nadu. This cyclonic circulation extends up to 5.8 km above mean sea level and is tilting southwestwards. It is predicted to move west-northwestwards and weaken into a low-pressure system soon.

Meanwhile, private weather website Skymet has also issued a report stating that the cyclonic circulation forming over the North Andaman Sea may have the potential to evolve into a tropical storm. According to Skymet, the system is expected to move across the Myanmar-Thailand region and enter the east-central Bay of Bengal by October 19 or 20. As it moves towards the central parts of the Bay of Bengal, the circulation is likely to strengthen further.

The forecast highlights that conditions in the Indian seas are conducive for low-pressure systems to develop into tropical storms. The potential for intensification is heightened by the availability of oceanic heat and sufficient sea travel. As a result, the entire coastline from Odisha, West Bengal, Bangladesh, and Myanmar could be vulnerable to the impact of this potential storm, urging coastal regions to stay alert and prepared.
