2010–11 South Pacific cyclone season#Severe Tropical Cyclone Yasi

Ahead of the cyclone season, RSMC Nadi, TCWC Wellington, the Australian Bureau of Meteorology (BoM), the New Zealand National Institute of Water and Atmospheric Research (NIWA) and various other Pacific Meteorological services, all contributed towards the Island Climate Update tropical cyclone outlook that was released during October 2010.{{cite journal|url=http://www.niwa.co.nz/climate/icu/island-climate-update-121-october-2010/sw-pacific-tc-guidance-for-the-2010-11-season|journal=Island Climate Update|publisher=National Institute of Water and Atmospheric Research|title=SW Pacific TC guidance for the 2010–11 season|date=November 26, 2010|access-date=November 16, 2014}} The outlook took into account the moderate-strong La Niña conditions that had been observed across the Pacific and analogue seasons that had La Niña conditions occurring during the season.{{cite web|publisher=National Institute of Water and Atmospheric Research|url=http://www.niwa.co.nz/news/zelia-consistent-tropical-cyclone-outlook|title=Zelia consistent with tropical cyclone outlook|work=NIWA |date=January 18, 2011|access-date=November 16, 2014}} The outlook called for a normal or above average number of tropical cyclone occurring during the season, with nine to twelve named tropical cyclones, to occur between 135°E and 120°W compared to an average of nine. At least three of the tropical cyclones were expected to become category 3 severe tropical cyclones, while one was expected to become a category 4 severe tropical cyclone. In addition to contributing towards the Island Climate Update outlook, RSMC Nadi and the BoM issued their own seasonal forecasts for the South Pacific region. The BoM issued 2 seasonal forecasts for the South Pacific region between 142.5°E – 165°E and one for the Eastern Southern Pacific region between 165°E – 120°W. They noted that the western region had a 79% chance of being above average activity with seven to eight tropical cyclones expected to form, compared to an average of five tropical cyclones. The eastern region had a 33% chance of being above average with five to six tropical cyclones predicted, compared to an average of seven tropical cyclones.

Within their outlook RSMC Nadi predicted that between seven and nine tropical cyclones, would occur within the basin compared to an average of around 8.9 cyclones. They also reported that the tropical cyclone genesis trough was expected to be located within the Coral Sea area near to and to the west of the International Date Line. This was based on the expected and predicted ENSO conditions, and the existence of the Pacific warm pool of sub-surface temperature anomalies in this region. The Island Climate Update outlook assessed the risk of a tropical cyclone affecting a certain island or territory. As the tropical cyclone genesis trough was expected to be located within the Coral Sea area near to and to the west of the International Date Line, normal or slightly above normal activity was expected for island nations within the Coral Sea. It was also predicted that the risk of tropical cyclones affecting island nations located to the east of the International Date Line would be reduced during the season. It was predicted that Papua New Guinea, Vanuatu, New Caledonia, New Zealand and the Solomon Islands had an elevated chance of being affected by a single or multiple tropical cyclones. Fiji and Tonga were predicted to have a near normal chance, while other island nations had a low or reduced chance of being affected by a tropical cyclone.

17 tropical disturbances developed during the 2010–11 South Pacific tropical cyclone year, with 14 developing into tropical depressions and 8 becoming tropical and severe tropical cyclones.

On March 22, RSMC Nadi analyzed that a Tropical Disturbance had formed about 70 miles NNW of Fonualei island, Tonga. Later the same day it was upgraded to a Tropical Depression, and cyclone warnings were issued for islands in the Eastern Division of Fiji. As it neared the International Date Line it continued to strengthen and was named Tropical Cyclone Bune, and as it moved generally southwards it reached category 3 by March 25.[https://www.australiasevereweather.com/tropical_cyclones/2010_2011/oper/tropical_cyclone_bune.htm Season 2010-2011 Tropical Cyclone BUNE Track Map] Tropical Cyclone Track Maps for Australia and the Southern Hemisphere.
