Bay to host a Tropical Storm

Simultaneously, Bay of Bengal is expected to host a tropical storm. Numerical weather models indicate the development of a low-pressure system in the south Andaman Sea, forecasted to concentrate into a depression and subsequently intensify into a cyclone by December 2nd. The track of this system is uncertain for now due to complex atmospheric dynamics involved, but consensus among models is anticipated by thursday or friday. Presently, the prevailing trend suggests the cyclone may pass 150-200 km off Chennai coast before moving towards South/Central Andhra Pradesh. So the impact to Chennai and other parts of TN will depend on the proximity of the system.
