A storm developing off the Western Australian coast is expected to turn into a cyclone before making landfall, bringing powerful winds and potential flooding.

Residents in areas from Port Hedland to Broome have been told to prepare for cyclonic weather ahead of the intensifying storm.

The Bureau of Meteorology predicts the tropical low over the Indian Ocean to the northwest of Derby will strengthen into a category-one cyclone on Tuesday afternoon.

It is expected to continue growing in intensity, potentially becoming a category-four cyclone by Thursday before shifting over land.

The WA Department of Fire and Emergency Services said there was still uncertainty over the path of the system, but it could cross the coast as a severe tropical cyclone near Eighty Mile Beach on Thursday or Friday.

Senior Meteorologist, Miriam Bradbury told the ABC, we will see more severe weather in the region from tomorrow.
