A cyclone watch has been issued for a developing tropical low off WA's north west coast.
The alert is current for coastal areas from Pardoo to Onslow, including Port Hedland and Karratha.
The tropical low is about 55 kilometres south-south-west of Broome and moving slowly south-west.
The Bureau of Meteorology says the low may develop into a tropical cyclone by Wednesday.
Gales are not expected in coastal areas within the next 24 hours.
