According to the Indian Meteorological Department, a low-pressure area over the north Andaman Sea and surrounding areas of the south Andaman Sea and southeast Bay of Bengal is likely to gradually intensify into a cyclonic storm over the west-central and surrounding eastcentral Bay of Bengal by Monday (IMD). Around Saturday, October 22, the system is predicted to travel west-northwestward, concentrate into a depression over East Central and the surrounding Southeast Bay of Bengal, and then further deepen into a deep depression the following day.
By Monday, October 24, the system is expected to recurve northward, develop, and become a cyclonic storm over the westcentral and adjacent eastcentral Bay of Bengal, according to the weather forecasting office.
For issuing advisories and identifying tropical cyclones, six regional specialised meteorological centres (RSMCs) and five regional Tropical Cyclone Warning Centers (TCWCs) are required. 13 member nations of the WMO/ESCAP Panel, including Bangladesh, India, Iran, Maldives, Myanmar, Oman, Pakistan, Qatar, Saudi Arabia, Sri Lanka, Thailand, United Arab Emirates, and Yemen, are served by IMD, one of the six RSMCs, which issues tropical cyclone and storm surge advisories.
One of the names Thailand recommended for the cyclone is Sitrang (pronounced Si-trang).
