Post-2008 Southern Hemisphere tropical cyclone seasons

The Post-2008 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.

Storm Names

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.

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.

Southeast Indian Ocean/Western Australia

The following names will be used in the post-2008 seasons. The list is circular, so names will be used sequentially and only once. All the names from list 1 have already been used and a few names from list 2. Only names that have not yet been used will be shown here.

Arafura Sea and Gulf of Carpentaria/Northern Australia

The following names will be used in the post-2008 seasons. The list is circular, so names will be used sequentially and only once. All the names from list 1 have already been used and a few names from list 2. Only names that have not yet been used will be shown here.

Coral Sea/Eastern Australia

The following names will be used in the post-2008 seasons. The list is circular, so names will be used sequentially and only once. All the names from list 1 and 2 have already been used and a few names from list 3. Only names that have not yet been used will be shown here.

Solomon Sea and Gulf of Papua/Papua New Guinea

The following names will be used in post-2008 seasons. It is in effect since 2005 and names are used sequentially. List B details replacement names for list A which will be added in the bottom of list A to maintain the alphabetical order.

South Pacific/Fiji

The following names will be used in the post-2008 seasons. The list is circular, so names will be used sequentially and only once. List E is a list of replacement names. All the names have now been use up from list A so we are on to List B. Only names that have not yet been used will be shown here.
