History
Severe Tropical Cyclone Lena developed during the 1992–93 Australian region cyclone season, forming as a tropical low off the north Kimberley coast and reaching tropical cyclone intensity on 24 January 1993. The system was named by the Bureau of Meteorology's Tropical Cyclone Warning Centre in Perth.
Lena achieved its peak intensity early on 26 January, briefly reaching Category 3 on the Australian scale with maximum sustained winds of around 120 km/h. Environmental changes caused it to weaken rapidly back to Category 1 that same day, a strength it maintained while drifting westward across open waters well off the Pilbara coast. Around 30 January, a significant shift in steering currents caused the cyclone to reverse direction entirely, tracking back east-southeast over the same ocean area it had previously crossed. Moving over cooler, upwelled waters, Lena lost organisation and fell below cyclone intensity by 2 February 1993, giving it a total lifespan of approximately ten days.
The storm's most notable characteristics were its prolonged duration and its highly erratic, looping track. Lena remained several hundred kilometres offshore throughout its entire life and never made landfall. As a result, there were no reported casualties, no structural damage on the mainland, and no significant disruption to offshore industry along the North West Shelf.
