A low moved off the Kimberley coast during 24 January. This system moved steadily west and intensified into Tropical Cyclone Dominic by 0900 WDT 26 January. Dominic turned southwest and reached category 2 intensity before crossing the west Pilbara coast near Onslow at 0600 WDT 27 January. Wind gusts to 133 km/h (72 knots) were recorded at Onslow Airport and there was some minor structural damage and power lines brought down. Dominic weakened quickly over land although the remains of the system caused heavy rainfall and flooding in many parts of southern Western Australia. The Gascoyne River inundated many parts of Carnarvon. A train was derailed east of Kalgoorlie on 30 January apparently because of flowing water. Flash flooding was also reported in the Wheatbelt including York and Quairading.
