Meteorological history
editThis section needs to be updated.(October 2023) |
On 21 October, a low-pressure area was formed in the Bay of Bengal. On the same day, JTWC issued a TCFA and classified the disturbance as Tropical Depression 06B. Due to its favorable conditions, 06B intensified into a cyclonic storm, which granted the name Hamoon by the IMD. On 24 October, Hamoon intensified into a category 2-equivalent cyclone, reaching its peak intensity with sustained winds of 120 km/h (75 mph) and gusts of 140 km/h (85 mph). The storm landed on Cox's Bazar on the Bangladesh coast, bringing strong winds and intense rainfall into that area.[2] Hamoon dissipated over Myanmar on October 25 as it moved inland.
Impact

editCyclone Hamoon brought heavy rainfall and strong winds to coastal Bangladesh, with seventeen killed and many injured.[3]
Response
editBangladesh
editThe government has implemented comprehensive measures to evacuate 1.5 million people from vulnerable areas, relocating them to government shelters across 10 coastal districts in preparation for Cyclone Hamoon.[4] The Chittagong Port Authority has taken precautionary measures by dispatching 88 ships to the deep sea in order to safeguard against potential damages from Cyclone Hamoon.[5]
Volunteers from various organizations, including the Bangladesh Water Development Board, Fire Service, Red Crescent, and other volunteer groups, are prepared to handle the situation.[citation needed] Additionally, the local administration has urged fishermen to seek safe shelter through loudspeakers, and launches have been instructed to anchor in secure positions.[citation needed] The Bangladesh Inland Water Transport Authority (BIWTA) took the precautionary step of suspending the movement of all types of vessels in the Barisal division on Tuesday.[6][7]
India
editSeveral districts of Tamil Nadu are expected to experience heavy rainfall for the next two days as cyclonic storm Hamoon is anticipated to further intensify. A yellow warning has been issued for six districts in the state.[8]
