Cyclone Gamane in Madagascar
Cyclone Gamane made landfall in Madagascar on 27 March, leaving 18 dead and affecting thousands of people.
The storm was originally forecast to pass by the northern coast of the country, but unexpectedly changed course on 27 March, crossing over Vohémar district in the early hours of the day and continuing across the north-eastern districts of the island. The slow-moving storm dissipated in the afternoon on 28 March.
Gamane brought heavy rain to the northern areas of Madagascar, and strong winds, causing floods and damage to infrastructure. It is estimated that more than 20,000 people were forced from their homes by the storm.
