Severe Tropical Storm Domoina in 1984 caused
100 year floods in
South Africa and record rainfall in
Swaziland. The fourth
named storm of the
season, Domoina developed on January 16 off the northeast coast of
Madagascar. With a
ridge to the north, the storm tracked generally westward and later southwestward. On January 21, Domoina struck eastern Madagascar, the third storm in six weeks to affect the nation; collectively, the storms caused 42 deaths and $25 million in damage (1984
USD). After crossing the country, Domoina strengthened in the
Mozambique Channel to peak
10 minute sustained winds of 95 km/h (60 mph). On January 28, the storm made
landfall in southern
Mozambique, and slowly weakened over land. Domoina crossed into Swaziland and later eastern South Africa before dissipating on February 2.
