Part of the 1977–78 Australian region cyclone season

Severe Tropical Cyclone Alby was regarded as the most devastating tropical cyclone to impact southwestern Western Australia on record. Forming out of an area of low pressure on 27 March 1978, Alby steadily developed as it tracked southwestward, parallel to Western Australia. Between 1 and 2 April, the storm quickly intensified and attained its peak intensity as a Category 5 cyclone on the Australian cyclone intensity scale. After turning to the southeast, the storm underwent an extratropical transition as it neared Cape Leeuwin. The storm brushed the cape on 4 April, bringing hurricane-force winds, before rapidly losing its identity the following day.

In Western Australia, the combination of Alby's fast movement and hurricane-force winds caused widespread damage. Along the coast, large swells flooded low-lying areas and numerous homes lost their roofs from high winds. Further inland, bushfires were worsened by the storm as it brought little rain, generally less than 20 mm (0.79 in) along the coast. These fires burned roughly 114,000 hectares (281,700 acres). Cyclone Alby and the associated brushfires caused five deaths, with the heaviest damage in the town of Albany, Western Australia.[1] A report at the time noted that "The Perth metropolitan area and nearly every town from Geraldton to Albany was extensively damaged."[2] The resulting damage was extensive, with monetary losses reaching A$50 milelion (US$45 million). According to a Canadian newspaper, the Associated Press reported initially that officials in Perth said that "A tropical cyclone Tuesday tore across the southwestern tip of Australia, killing at least five persons and sparking brushfires that destroyed two towns,"[3], but the two towns supposedly destroyed by fire were not identified, nor was there a report in the local press or subsequent investigations.
