The Post-2007 Southern Hemisphere tropical cyclone seasons will be ongoing events in the annual cycle of tropical cyclone formation. They will run from July 1, through June 30, reaching its peak mid-February to early March.

[edit] Storm Names

[edit] Southwest Indian Ocean

According to the operational plan, a tropical disturbance is named when reaching the stage of moderate tropical storm. If a tropical disturbance reaches "moderate tropical storm" status west of 55 degrees east longitude, then the Sub-regional Tropical Cyclone Advisory Centre in Madagascar assigns the appropriate name to the storm. If a tropical disturbance reaches "moderate tropical storm" status between 55 and 90 degrees east longitude, then the Sub-regional Tropical Cyclone Advisory Centre in Mauritius assigns the appropriate name to the storm. A new annual list is used every year so there is no need to consider the retirement of names.

[edit] Southeast Indian Ocean and South Pacific

According to the operational plan, non-frontal low pressure systems of synoptic scale developing over warm waters are named whenever observations and/or Dvorak intensity analysis indicate the presence of gale force or stronger winds near the centre. It should be emphasized that an unnamed tropical system may have gales in one or more quadrants, but not near the centre. This is quite different from the Atlantic standard.

Names are assigned by the Australian Bureau of Meteorology or Papua New Guinea (for 90°E-160°E) or Fiji Meteorological Service (for 160°E-120°W). No tropical cyclone has ever been observed in South Pacific Ocean east of 120°W based on the JTWC's best track data. If there is one in the future, it is unclear how it will be handled. The most probable solution is to leave it unnamed like the South Atlantic tropical cyclone.
