Cyclone Felicie was a slow moving cyclone that made a large number of landfalls in Madagascar, 4, in addition to a single landfall in Mozambique, which reportedly killed 30 people. The storm followed a very erratic track due to unusual steering patterns, and went through many cycles of strengthening and weakening as it slowly trudged to the south. Felicie reached Tropical Cyclone status three separate times, before finally becoming extratropical southwest of Madagascar.Global tropical/extratropical cyclone climatic atlas Tropical Storm Felice, 17 January- 5 February 1996 National Climatic Data Center February 11, 2019 SWI 1971_2

On January 19, Severe Tropical Cyclone Myrtle entered the South-West Indian Ocean; therefore, it was assigned a second name, Ginette. The next day, Ginette reached hurricane status and developed a clear eye as it traveled generally west-southwestward. On January 22, Ginette curved southwestward and came within 72 km mi off us of the island of Rodrigues. On Rodrigues, winds as high as 150 km/h mph on were recorded along with a minimum barometric pressure of 989 mbar inHg on. Throughout the next two days, Ginette approached the island of Reunion, causing stormy weather that lasted until January 29. In Reunion, swells associated with Ginette reached 6 m ft off us at times. On January 25, Ginette became stationary while located south of Reunion. The next day, Ginette encountered a ridge which caused it to execute a small clockwise loop. After completing the loop, Ginette accelerated southeastward and gradually weakened. By January 31, Ginette had transitioned into an extratropical cyclone.SWI 1971_1 Hurricane Ginette, 17–31 January February 12, 2019 Global tropical/extratropical cyclone climatic atlas 1996 National Climatic Data Center
