On 27 March, a tropical depression developed in the eastern Indian Ocean between Indonesia and Australia. It drifted to the southwest, and slowly strengthened into a tropical storm on 29 March. Alby continued slowly southwestward, and attained cyclone status on 30 March. The rate of intensification, which was slower earlier in its life, became more steady towards strengthening, and reached the equivalent of Category 3 status on 1 April. Tropical Cyclone Alby turned more to the south, and quickly reached a peak of 135 mph (217 km/h) later on 1 April. After maintaining its strength for 30 hours, Alby weakened as it turned to the southeast. Its forward momentum increased over the southeast Indian Ocean, and Alby was only an 85 mph (137 km/h) cyclone as it passed off the southwest coast of Australia on 4 April. It continued rapidly to the southeast, and became extra-tropical on 5 April while south of the continent.
On 4 April, Tropical Cyclone Alby passed close to the southwest corner of Western Australia, killing five people and causing widespread but mostly minor damage to the southwest. The damage bill was estimated to be $39 million (2003 dollars). A man was blown from the roof of a shed and a woman was killed by a falling pine tree. Another man was killed when a tree fell on the bulldozer he was operating and two men drowned when their dinghy overturned at Albany. Storm surge and destructive waves caused coastal inundation and erosion from Perth to Busselton, damaging the Busselton Jetty and Fremantle Harbour. Fires fanned by the strong winds burned an estimated 1,140 km2 (440 sq mi) of forest and farming land.
