Flood Watch Number: 5

Flooding is possible in the Onslow Coast and Pilbara Coastal Rivers due to unseasonal heavy rainfall from Thursday through to Friday.

A trough and associated rain band lies over the northeast Gascoyne, Pilbara and Interior, with heavy falls and possible flooding in the Pilbara for the remainder of Thursday. The rain band will contract eastwards over the next couple of days, before gradually dissipating on Saturday.

Although catchments in the region are very dry, they can respond quickly to the intense rainfall forecast.

Widespread daily rainfall totals of 25 to 75 mm, with isolated daily falls of up to 150 mm are forecast as the system tracks north over the next few days.

Forecast rainfall in the affected catchments is expected to result in river rises, areas of flooding and may adversely affect road conditions. Some roads may become impassable and some communities may become isolated.

Catchments likely to be affected include:
De Grey River

Pilbara Coastal Rivers

Fortescue River

Onslow Coast
