1992–93 Australian region cyclone season

The 1992–93 Australian region cyclone season was a below average Australian cyclone season. It was also an event in the ongoing cycle of tropical cyclone formation. It ran from 1 November 1992 to 30 April 1993. The regional tropical cyclone operational plan also defines a tropical cyclone year separately from a tropical cyclone season, and the "tropical cyclone year" ran from 1 July 1992 to 30 June 1993.

Tropical Cyclone Monty
Category 2 tropical cyclone (Australian scale)

Adel lasted from 11–16 May 1993. During its life, it passed over Bougainville Island and near Goodenough Island, leaving two drowned and a total of at least 15 missing. Leaves were blown from trees, and 345 houses were destroyed, along with a radio tower that was bent over.[4] The track, especially its intensity and formation area, are highly unusual as a tropical cyclone in this region (the north coast of Papua New Guinea) has occurred less than 10 times in history.
