Flood Watch Number: 2

Flooding is possible in the Gascoyne River, Wooramel River, Lyndon-Minilya Rivers, Onslow Coast, Ashburton River and Onslow due to unseasonal heavy rainfall from Tuesday through to Thursday.

A rain band associated with a strong cold front to the south will move east across the Pilbara during Tuesday to Thursday with heavy falls expected.

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

Widespread daily rainfall totals of 50 to 100 mm, with isolated daily falls of up to 120 mm are forecast as the system tracks north east over the next few days. Intense rainfall may fall over a very short duration.

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:

Fortescue River
Onslow Coast
Ashburton River
Lyndon-Minilya Rivers
Gascoyne River
Wooramel River
