List of extremely severe cyclonic storms

Cyclone Biparjoy, at peak intensity while approaching the India-Pakistan border region on June 12, 2023

Behind super cyclonic storms, extremely severe cyclonic storms are the second-highest classification on the India Meteorological Department (IMD)'s intensity scale. There have been 32 of them since reliable records began in 1960. The most recent extremely severe cyclonic storm was Cyclone Biparjoy of the 2023 North Indian Ocean cyclone season.

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] The basin is officially monitored by the India Meteorological Department's Regional Specialized Meteorological Centre in New Delhi.[1] Within the basin, an extremely severe cyclonic storm is defined as a tropical cyclone that has 3-minute mean maximum sustained wind speeds between 90–119 knots (165–220 km/h; 105–135 mph).[1]
