Tropical Low 30U

30 March - 3 April 2022


Tropical low 30U tracked off the west coast of Western Australia and while it did not cause gale-force winds, it did lead to heavy rain and associated flooding near the west coast.

Rainfall totals between 100-200 millimetres (mm) fell along the Gascoyne coast between Shark Bay and Exmouth. Localised flooding caused road disruptions including the closure of the North West Coastal Highway from south of Carnarvon to the Shark Bay road for two days. Flash flood impacts were reported in Carnarvon with minor inundation of some roads, commercial and residential buildings. Heavy rainfall resulted in very quick and significant river responses from local runoff in the Wooramel, Gascoyne, Greenough, and Ashburton River catchments.
