The island group has a history of deadly and disruptive cyclones. In February and April 1898, cyclones moved through the islands, causing a famine. After cyclones struck in December 1904 and 1905, another famine occurred in the islands, killing 490 people. A cyclone in December 1950 killed 585 people. In January 1983, Severe Tropical Storm Elinah killed 33 people from high winds and floods. In 2019, Cyclone Kenneth killed nine people and injured 200 others.
Climatology
Due to their low latitude, the islands are rarely affected by tropical cyclones.[1]
