The 1976–77 South-West Indian Ocean cyclone season was a below-average cyclone season. The season officially ran from November 1, 1976, to April 30, 1977.
This system formed west of Diego Garcia on November 15. For the next eleven days, Brigitta meandered southward as a tropical depression. After assuming a westward course, Brigitta strengthened into a tropical storm on November 26. The system reached its peak intensity as it passed by the northern tip of Madagascar. The system moved through the Comoros Islands, and then turned southward into Mozambique.
Cyclone Emilie struck the east coast of Mozambique and northeastern South Africa in February 1977. Heavy flooding in the Limpopo Valley killed at least 300 people.
