23 March while moving off the west coast of Madagascar. It turned west on 24
March and moved into Mozambique on 25 March. The storm maintained hurricane
intensity during this period, with maximum sustained winds estimated at 85 kt
just prior to landfall. Nadia quickly dissipated as a tropical cyclone over
