Extremely Severe Cyclonic Storm Mocha was an extremely powerful tropical cyclone in the North Indian Ocean which affected Myanmar and parts of Bangladesh in May 2023. The second depression and the first cyclonic storm of the 2023 North Indian Ocean cyclone season, Mocha originated from a low-pressure area that was first noted by the India Meteorological Department (IMD) on 8 May. After consolidating into a depression, the storm tracked slowly north-northwestward over the Bay of Bengal, and reached extremely severe cyclonic storm intensity. After undergoing an eyewall replacement cycle, Mocha rapidly strengthened, peaking at Category 5-equivalent intensity on 14 May with winds of 280 km/h (175 mph), tying with Cyclone Fani as the strongest storm on record in the north Indian Ocean, in terms of 1-minute sustained winds. Mocha slightly weakened before making landfall, and its conditions quickly became unfavorable. Mocha rapidly weakened once inland and dissipated shortly thereafter.
