Cyclone Sitrang, near peak intensity on October 24, 2022

A Cyclonic Storm is a category used by the India Meteorological Department (IMD) to classify tropical cyclones, within the North Indian Ocean tropical cyclone basin between the Malay Peninsula and the Arabian Peninsula. Within the basin, a cyclonic storm is defined as a tropical cyclone that has 3-minute mean maximum sustained wind speeds of between 35–48 knots (65–89 km/h; 40–55 mph).

Background

The North Indian Ocean tropical cyclone basin is located to the north of the Equator, and encompasses the Bay of Bengal and the Arabian Sea, between the Malay Peninsula and the Arabian Peninsula.[1][2] The basin is officially monitored by the India Meteorological Department's Regional Specialized Meteorological Centre in New Delhi, however, other national meteorological services such as the Bangladesh and Pakistan Meteorological Department's also monitor the basin.[1][2] The Cyclonic Storm category has historically been used to classify all tropical cyclones with winds between 35–48 knots (65–89 km/h; 40–55 mph).[1][2]
