Residents in the Midwest Gascoyne and Pilbara regions of Western Australia are preparing for potential flooding due to heavy rain forecasted for the start of the week.

The Department of Fire and Emergency Services has issued an alert warning of daily rainfall totals of 30-80 millimetres, with isolated amounts up to 100mm, which could cause flooding and road closures.

Residents are advised to prepare emergency kits, stock up on essentials, and move belongings, cars, equipment, livestock, and pets to higher ground to avoid being stranded.

The Bureau of Meteorology has warned of the risk of river rises and the impact on isolated communities.

Cooler weather with cold and frosty mornings is expected in most Australian capitals, especially in eastern Australia.
