High Quality Content by WIKIPEDIA articles! The 1990–91 South Pacific cyclone season was one of the least active cyclone seasons, with only three tropical cyclones occurring within the South Pacific to the east of 160°E. The season officially ran from November 1, 1990, to April 30, 1991 with the first disturbance of the season forming on November 23 and the last disturbance dissipating on May 19. This is the period of the year when most tropical cyclones form within the South Pacific Ocean. During the season there was no one killed from tropical disturbances whilst they were within the South Pacific. However six people were killed by Cyclone Joy when it made landfall on Australia. As a result of the impacts caused by Joy and Sina, the names were retired from the tropical cyclone naming lists.
