Cyclone Hamoon
North Indian Ocean cyclone in 2023

Very Severe Cyclonic Storm Hamoon 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. Five people died and 63 others sustained injuries as Hamoon made its devastating landfall in Bangladesh on 26 October. Over 6 million people 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.

Why this record matters
“Cyclone Hamoon” is worth following because a concise public description often conceals a longer documentary argument. Here, Cyclone, Hamoon and North provides the most credible route into that argument.
The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated May 1, 2026. The linked authority identifier is Q123170303. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2023.
Modern boundaries and familiar names can conceal earlier jurisdictions or structures that do not align with the present site. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
