The first named storm was Severe Tropical Storm Alexandra, which developed on December 18 from the monsoon trough; many other storms during the year originated in this manner. Tropical Storm Bryna was the only tropical storm of the season to make landfall, having struck northeastern Madagascar on January 2. The basin was most active in February, when five named storms developed, including Tropical Depression Elizabetha which struck western Madagascar. In early March, Cyclone Harriet entered the basin from the Australian region and was renamed Heather. It intensified to peak winds of 165 km/h (105 mph), making Heather the strongest storm of the season. In April, another cyclone – Jane – crossed from the Australian region and was renamed Irna, which reentered the Australian region on April 19 to end tropical activity within the basin.
