LEAH
1972-73 season · AU197273_08U
History
Severe Tropical Cyclone Leah developed close to the Western Australian coast on 27 February 1973. Once formed, the system tracked away from the mainland on a generally southwestward heading, moving out over the waters of the eastern Indian Ocean. Leah proved to be an unusually long-lived system, persisting for close to a fortnight before finally weakening and dissipating on 11 March. It was classified as a severe tropical cyclone during its lifetime, and no coastal crossing was recorded.
Leah was one of a number of systems to affect the Australian region during the active 1972–73 season.
