Heavy rain and gales expected over the northwest Pilbara as a tropical low approaches.
At 8:00am AWST, a tropical low was located about 300km north of Onslow, moving south southwest. The low is expected to reach the coast later on Thursday or early Friday and may travel parallel to the Gascoyne coast. The tropical low is not expected to intensify into a tropical cyclone but is likely to cause a period of heavy rainfall and squally winds.
Along the northwest Pilbara coast between Mardie and Coral Bay, sustained GALES are possible from late this evening until Friday morning.
The weather system may also cause DAMAGING WIND GUSTS to 100 kilometres per hour that could result in DAMAGE TO HOMES AND PROPERTY in or near thunderstorms.
HEAVY RAINFALL that may lead to FLASH FLOODING is possible with isolated falls of 50mm to 100mm.
Tides will be higher than normal in coastal parts.
The passage of a tropical low off the northwest Pilbara is typical for this time of the year but winds and rain may cause damage to property and make road conditions hazardous.
Severe Weather events are forecast to affect Exmouth, Onslow, Barrow Island, Coral Bay and North West Cape.
