Very Severe Cyclonic Storm Hamoon[a] (/hɑːˈmun/) was a moderately strong tropical cyclone that affected Bangladesh, India, and Myammar during October 2023. The fourth named storm of the 2023 North Indian Ocean cyclone season, Hamoon formed from a low-pressure area over the west-central Bay of Bengal on 21 October. Initially slowly developing, after it entered an area favorable for development, it rapidly intensified, peaking as a very severe cyclonic storm on 24 October. However, soon after, Hamoon weakened due to wind shear, later making landfall in Bangladesh as a severe cyclonic storm. Once inland, Hamoon degenerated into a low-pressure area, last being noted on 26 October. Prior to Hamoon's landfall, officials in Bangladesh ordered the evacuation of over 1.5 million people as it was expected to have a severe impact on the nation. As Hamoon made its devastating landfall in Bangladesh on 26 October, five people died from Hamoon's winds. Additionally, 63 others sustained injuries. Over 6 million lost power, primarily in the port of Cox's Bazar, where several days after Hamoon made landfall, over 5 million were still without power. Elsewhere, a weakening Hamoon mainly brought light rainfall to India and Myanmar. In total, according to Aon, the cyclone caused around $250 million in damage.
