Two tropical cyclones could develop in waters off northern Western Australia, the Bureau of Metereology says.

A slow-moving tropical low located about 550km north of Karratha, off the Pilbara coast, may become a tropical cyclone by Tuesday.

The second is in the Timor Sea, west of the Tiwi Islands, and may develop into a tropical cyclone late on Tuesday or early Wednesday.

If the low stays out over open waters it may become a cyclone, but if it moves over land it will bring very heavy rainfall, possible flooding and squally winds.

The bureau says if the cyclones develop the first will be called Yvette, and the second will be called Alfred.

On average, there are five tropical cyclones in waters off northwest Australia each season.

More cyclone activity is expected this season than last, where only one cyclone made landfall in the Pilbara in January.
