Intense Tropical Cyclone Nadia was a powerful tropical cyclone that struck both Madagascar and Mozambique in March 1994. It formed on 16 March and moved westward for the first ten days of its duration. Warm waters and low wind shear allowed for the storm to gradually strengthen. After developing a well-defined eye, Nadia intensified to reach winds of 175 km/h (110 mph (10 minute sustained)) early on 22 March, according to Météo-France (MF). In contrast, the Joint Typhoon Warning Center (JTWC) estimated winds of about 220 km/h (140 mph 1 minute sustained). On 23 March, the cyclone struck northern Madagascar, causing flooding and localized damage where it moved ashore. There were 12 deaths in the country. Nadia emerged into the Mozambique Channel as a weakened storm, although it reintensified slightly before making landfall in northeastern Mozambique on 24 March. The storm turned southward through the country, emerging over water on 26 March. It turned to the northeast and meandered over waters before dissipating on 1 April.
Damage was heaviest in Mozambique, estimated at $20 million (1994 USD). Cyclone Nadia severely affected four provinces in the country, primarily Nampula Province where it moved ashore. There, 85% of the houses were destroyed, and across its path, the cyclone left 1.5 million people homeless. High winds caused widespread power outages, left areas without water, and significantly damaged crops, notably the cashew crop. The storm struck before the harvest, and lack of food resulted in 300 deaths in the months after the storm. Across Mozambique, Nadia directly caused 240 deaths and injured thousands. Effects spread as far inland as Malawi.
