Garance - the equivalent of a Category 2 Atlantic hurricane - made landfall on the northern coast of the mountainous island, France's meteorological agency said.
Garance is the strongest storm to hit the territory, located about 400 miles off the coast of Madagascar, since Tropical Cyclone Firinga in January 1989.
Authorities issued a purple cyclone warning, their highest level, for the entirety of the island as the storm is packing a punch and bringing heavy rainfall, gusty winds and powerful waves to the territory. That was later lowered to a red warning.
Winds could gust over 200 kilometers (124 miles) per hour and rainfall totals could exceed 200 mm (7.8 inches).
