Gezani had been rapidly intensifying on 10 February prior to landfall (ADT<\/strong><\/a> | SATCON<\/strong><\/a>). After landfall, the eye of Gezani quickly became cloud-filled as the storm interacted with the topography<\/strong><\/a> of the island. Gezani was responsible for at least 41 fatalities, and displaced more than 16000 residents.<\/p>\n
