Flood Watch Number: 1

Flooding is possible in Gascoyne River, Wooramel River, Murchison River, Lyndon-Minilya Rivers and Ashburton River due to unseasonal heavy rainfall from Monday evening through to Thursday.

A strong cold front combined with a rich tropical moisture feed will bring a rain band over western parts of WA from late Monday. Unseasonal heavy rainfall will develop in the northern Central West, western Murchison, western Gascoyne district during Monday night and Tuesday, before extending throughout the Gascoyne and into the Pilbara from late Tuesday and persist until at least Thursday.

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 150 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:

Ashburton River
Lyndon-Minilya Rivers
Gascoyne River
Wooramel River
Murchison River
