Cyclone Georgette was the longest lasting tropical cyclone in the South-West Indian Ocean basin since the advent of satellite imagery.[2] It formed on January 10, 1968, well to the northeast of the Mascarene Islands. Tracking generally westward, Georgette struck northern Madagascar on January 15 as a tropical storm. It moved southwestward in the Mozambique Channel, crossing over eastern Mozambique on January 19. It quickly reached open waters while gradually intensifying, executing a loop off of eastern Mozambique. Georgette continued to the southeast, passing over southern Madagascar on January 28.[3] It was last noted on February 2 after lasting for 24 days.[2]

Georgette killed one person in the Comoros, eight in Mozambique, and 23 in Madagascar. The storm brought heavy, but beneficial rainfall to Réunion.[4]
