'''Cyclone Seth''' was a [[tropical cyclone]] whose main impacts came after it degenerated into a [[remnant low]]. The fourth tropical low and fourth tropical cyclone of the 2021–22 Australian region cyclone season, Seth originated from a tropical disturbance in the [[Timor Sea]] and caused severe flooding in southeast Queensland and hazardous surf along the southeastern coast of [[Australia]]

Overall, Seth caused 2 fatalities, 1 in Queensland and 1 in [[New South Wales]]. Damage from the storm totaled $75 million [[USD]] at the least. Due to the damage caused by Seth in Queensland and New South Wales, the name ''Seth'' was retired and replaced with ''Stafford''.

{{Storm path|Seth 2021 track.png}}
During 23 December, the Australian [[Bureau of Meteorology]] started to monitor a tropical low, that had developed over the eastern Timor Sea, within the monsoon trough of low pressure.<ref name="TCR">{{cite report|publisher=Australian Bureau of Meteorology |access-date=4 December 2022 |url=http://www.bom.gov.au/cyclone/history/pdf/Seth_Report.pdf|title=Tropical Cyclone Seth|author=Courtney, Joseph B|date=14 February 2022}}</ref>


On December 21, the Bureau of Meteorology began to monitor a developing area of thunderstorms, giving it the possibility of becoming a tropical low.<ref>{{Cite web |title=Tropical Cyclone Outlook {{!}} Ghostarchive |url=https://ghostarchive.org/archive/gD34F |access-date=2022-11-25 |website=ghostarchive.org}}</ref> Late the next day, the [[JTWC]] labeled the disturbance as ''Invest 97S,''<ref>{{Cite web |last=HOAREAU |first=PATRICK |title=Invest 97S likely to consolidate and intensify next 48H, 24/06utc |url=https://www.meteo974.re/Invest-97S-likely-to-consolidate-and-intensify-next-48H-24-06utc_a2178.html |access-date=2022-11-25 |website=Météo.Cyclones.World@PH |language=en-US}}</ref> and the BoM followed the next day.<ref>{{Cite web |title=Tropical Cyclone Outlook {{!}} Ghostarchive |url=https://ghostarchive.org/archive/q7Bop |access-date=2022-11-25 |website=ghostarchive.org}}</ref> On December 24, the disturbance continued organizing, and the BoM began to finally issue advisories on the disturbance, and the BoM gave it a chance of becoming a Category 1 tropical cyclone and made landfall near [[Darwin, Northern Territory|Darwin]].<ref>{{Cite web |title=Tropical Cyclone Forecast Track Map {{!}} Ghostarchive |url=https://ghostarchive.org/archive/ZIpGy |access-date=2022-11-25 |website=ghostarchive.org}}</ref> Later that day, the JTWC issued a TCFA.<ref>{{Cite web |last=HOAREAU |first=PATRICK |title=Invest 97S: still MEDIUM// Invest 98S now on the map, 29/06utc |url=https://www.meteo974.re/Invest-97S-still-MEDIUM-Invest-98S-now-on-the-map-29-06utc_a2188.html |access-date=2022-11-25 |website=Météo.Cyclones.World@PH |language=en-US}}</ref><ref>{{Cite web |last=HOAREAU |first=PATRICK |title=Invest 97S: Tropical Cyclone Formation Alert North of Darwin, 24/2130utc |url=https://www.meteo974.re/Invest-97S-Tropical-Cyclone-Formation-Alert-North-of-Darwin-24-2130utc_a2181.html |access-date=2022-11-25 |website=Météo.Cyclones.World@PH |language=en-US}}</ref> However, by 18:00 the next day, the JTWC cancelled the TCFA due to the tropical disturbance moving over land without developing.<ref>{{Cite web |last=HOAREAU |first=PATRICK |title=Invest 97S over-land but still under watch// Invest 98S first update, 26/06utc |url=https://www.meteo974.re/Invest-97S-over-land-but-still-under-watch-Invest-98S-first-update-26-06utc_a2183.html |access-date=2022-11-25 |website=Météo.Cyclones.World@PH |language=en-US}}</ref> Later, the BoM also stopped issuing advisories due to lack of development, and gave the disturbance a low chance of development.<ref>{{Cite web |title=Australia - Invest 97S |url=https://www.pdc.org/weather-wall-updates/south-indian-ocean-invest-97s-4/ |access-date=2022-11-25 |website=Pacific Disaster Center |language=en-US}}</ref> Surprisingly, the low moved away from land and entered the [[Gulf of Carpentaria]].

Later, Seth reached peak intensity and the BoM upgraded it into a Category 2 tropical cyclone, with winds of around 110 km/h (70 mph). As Seth moved south, the BoM downgraded Seth into a Category 1 tropical cyclone. The next day, the BoM classified Seth as a subtropical cyclone.<ref>{{Cite web |title=Tropical Cyclone Tracks Maps : SETH - Australian Tropical Cyclones Southern Hemisphere Season 2021 - 2022 Hurricanes Typhoons Bureau of Meteorology BoM Data |url=https://australiasevereweather.com/tropical_cyclones/2021_2022/bom/tropical_cyclone_seth.htm |access-date=2022-11-25 |website=australiasevereweather.com}}</ref>
