The seventh named storm of the 2006–07 South-West Indian Ocean cyclone season, Gamede[nb 1] formed south of Diego Garcia on February 19 as a tropical disturbance.

When the storm stalled for a few days, it resulted in a prolonged period of heavy rainfall and high tides for the Mascarene Islands.

The deluge from Gamede caused flooding damage across Réunion, washing out a bridge in the southern portion of the island.

[6] An anticyclone over the nascent system provided weak wind shear and outflow to the north and east, both favorable conditions for development.

For over 90 hours, the cyclone remained within 400 km (250 mi) of Réunion, resulting in torrential rainfall in the island's mountainous region.

[10] This trend was temporary, as cooler waters and stronger wind shear began affecting Gamede on March 1, leaving the center exposed from the convection.

A ridge to its south caused the remnants of Gamede to slow again and execute a small loop southeast of Madagascar.

The MFR discontinued advisories on March 4, and the agency tracked the weakening low for two more days at it drifted westward.

[15] With its large circulation, Cyclone Gamede's rainbands affected islands in the south-west Indian Ocean for several days.

[4] Rough waves and strong winds affected a cruise ship to the east of Madagascar; several windows were broken, though no serious injuries were reported.

[16] Gamede lashed Madagascar's east coast with squalls of heavy rainfall and gusty winds, affecting areas struck by Tropical Storm Clovis two months earlier.

[19] High waves also struck the South African province of KwaZulu-Natal, forcing the temporary closure of beaches, roads, and the Port of Durban.

[20] Remaining near the Mascarene Islands for several days, Gamede dropped heavy rainfall on Mauritius, reaching 464 mm (18.3 in).

[21] The large size of the cyclone resulted in several days of very heavy, continuous rainfall in the mountainous region on Réunion island.

[12] Floods damaged roads in Saint-André and Salazie,[24] and washed out a 520 m (1,710 ft) bridge over the Saint Etienne River, part of Route nationale 1 connecting Saint-Louis and Saint-Pierre.

[31] The assistance provided €7.7 million for repairing roads and infrastructure, including rebuilding the destroyed bridge over the Saint Etienne River.

[32] Commerson Crater, located at an elevation of 2.3 km (1.4 mi),[5] recorded historic rainfall accumulations during the passage of Gamede.

The location reported 2,463 mm (97.0 in) in 48 hours, which is just short of the worldwide record set by an unnamed tropical cyclone in April 1958.
