Tropical Low 21U is located over water, just to the west of Broome. It is forecast to develop into a tropical cyclone by Saturday morning.
Over the weekend, 21U will continue to move in a general west southwest direction, roughly parallel to the Pilbara coast. It should continue to develop and is likely to reach category 2 intensity by Saturday evening. It may turn in a more southwesterly direction on Sunday and impact the western Pilbara.

Hazards:
DESTRUCTIVE WIND GUSTS to 140 km/h are possible for coastal parts of the Pilbara west of Wickham (including Karratha and Dampier) from Saturday afternoon if the centre of 21U approaches the coast. Destructive winds may extend further west along the coast towards Onslow and Exmouth during Sunday.
GALES with DAMAGING WIND GUSTS to 120 km/h are possible for coastal parts between Pardoo and Mardie during Saturday, extending west to Onslow and Exmouth on Sunday and through inland parts of the western Pilbara including Pannawonica.
Widespread moderate to locally HEAVY RAINFALL which may lead to FLASH FLOODING is possible from later tonight with this risk persisting through the weekend for the Pilbara coast.
Tides between Wickham and Exmouth are likely to rise above the normal high tide mark on Saturday and Sunday and LARGE WAVES may produce MINOR FLOODING of low-lying coastal areas.
