The 2018 North Indian Ocean cyclone season was an above-average period of tropical cyclone formation in the Northern Indian Ocean. The season featured 14 depressions, 10 deep depressions, 7 cyclonic storms, 5 severe cyclonic storms, 4 very severe cyclonic storms, and 1 extremely severe cyclonic storm. The season has no official boundaries,[citation needed] though storms typically form between April and December, with peaks in tropical cyclone activity from May–June and in November.[1]
The India Meteorological Department (IMD) is the official Regional Specialized Meteorological Centre for the Northern Indian Ocean basin,[2] and as such, it is responsible for tracking and issuing advisories on systems in the Arabian Sea and in the Bay of Bengal.[3] If tropical cyclones in the Northern Indian Ocean reach winds of 34 kn (63 km/h; 39 mph), it is given a name from a pre-defined naming list.[4] The Joint Typhoon Warning Center (JTWC) unofficially issues advisories on systems in the Northern Indian Ocean,[5] assigning tropical cyclones a numerical identifier[6] and suffixing it with the letter A for systems in the Arabian Sra and B for systems in the Bay of Bengal.[7] The IMD measures tropical cyclone wind speeds over a 3-minute average[8] while the JTWC uses a 1-minute average.[6]
