Cyclone Gretelle

Tropical Cyclone Gretelle was a deadly storm that struck southeastern Madagascar in January 1997. The seventh named storm of the 1996–97 South-West Indian Ocean cyclone season, Gretelle developed within the intertropical convergence zone on January 19, and gradually intensified while moving southwestward. On January 22, the storm intensified to tropical cyclone status while passing northwest of Réunion; there, Gretelle produced strong wind gusts and heavy rainfall in mountainous regions. Subsequently, the cyclone strengthened to reach peak 10-minute sustained winds of 140 km/h (85 mph). On January 24, Gretelle made landfall near Farafangana, the first in the region in 41 years. The cyclone weakened while crossing Madagascar, but restrengthened slightly in the Mozambique Channel. Gretelle meandered off the coast of Mozambique, bringing gusty winds that downed trees, but caused little damage. An approaching trough turned the cyclone to the southeast, and Gretelle dissipated on January 31 to the south-southwest of Madagascar.
