History
Tropical Cyclone Emma was one of the systems of the 2005–06 Australian region cyclone season, a period that produced above-average tropical cyclone activity. That season officially ran from 1 November 2005 to 30 April 2006, although the regional tropical cyclone operational plan also recognises a separate tropical cyclone "year" extending from 1 July 2005 through to 30 June 2006.
Tropical Cyclone Emma was an unusual, deceptive system during the 2005–2006 Australian region cyclone season. Despite remaining a low-end Category 1 storm with minimal wind damage, it generated a massive cloud band that dumped record-breaking rainfall across vast stretches of Western Australia, causing severe regional flooding.
Responsibility for tracking and warning on cyclones in this part of the world is shared between four Tropical Cyclone Warning Centres. Three of these are operated by the Australian Bureau of Meteorology, based in Perth, Darwin and Brisbane, while the fourth is TCWC Port Moresby in Papua New Guinea. Systems moving west of 90°E pass out of Australian jurisdiction and into the area handled by Météo-France on Réunion, where they may be renamed, while those crossing 160°E move into the South Pacific basin.
The 2005–06 season featured a varied mix of systems, ranging from weak tropical lows that never intensified beyond gale strength to severe tropical cyclones that reached the upper categories of the Australian intensity scale. Several of the season's cyclones remained offshore over the Indian Ocean, while others tracked across the Western Australian, Northern Territory and Queensland coastlines, bringing damaging winds, heavy rainfall and inland flooding. Cyclones that drifted inland as tropical lows after landfall often produced the season's most widespread rainfall impacts, cutting highways and isolating remote communities. Emma developed within this broader seasonal pattern and was named by the Bureau of Meteorology in accordance with the Australian region naming list.
