Cyclone Orson was the fourth most intense cyclone in the Australian
region on record. Forming out of a tropical low on April 17, 1989,
Orson gradually intensified as it tracked towards the west. After
attaining Category 5 intensity on April 20, the storm began to track
southward and accelerated. The following day, the cyclone reached its
peak intensity with winds of 250 km/h (155 mph, 10-minute sustained)
and a barometric pressure of 904 hPa (mbar). Orson maintained this
intensity for nearly two days before making landfall near Dampier. The
cyclone rapidly weakened after landfall as it accelerated to the
southeast. After moving into the Great Australian Bight on April 24,
the storm dissipated. Despite Orson's extreme intensity, damage was
relatively minimal as it impacted a sparsely populated region of
Western Australia. Five people were killed offshore and damages
amounted to A$20 million (US$16.8 million). The most severe impacts
took place in Pannawonica, where 70 homes were damaged. Due to the
severity of the storm, the name Orson was retired in 1990 and later
replaced by Olga.
