While the low remained offshore, damaging winds and heavy rainfall impacted parts of the Pilbara and Gascoyne districts on Thursday and Friday morning. 

The low whipped up damaging winds across parts of the Pilbara district on Thursday afternoon, with gusts reaching up to 95 km/h at Varanus Island, 87 km/h at Barrow Island as of 12:04pm and 12:39pm local time. 

The system has also generated heavy rainfall across parts of the Gascoyne and Pilbara during the 23 hours since 9am AWST on Thursday, with falls of 104.4mm recorded at Learmonth and 60.6mm at Carnarvon.  

This heavy rain will continue over the western Pilbara, Gascoyne and the far northwest corner of the Central West on Friday, with six hourly totals of 50 to 90mm possible in these regions.

This forecast rainfall has prompted a flood watch to be issued for parts of the Pilbara and Gascoyne coast after a dry summer.

Damaging wind gusts in excess of 90km/h could impact areas between Onslow and Billabong Roadhouse on Friday.
