Latest satellite images indicate Rusty may be going into a rapid intensification phase. Max sustained winds (as of 21Z) are up to 60 kts. The latest forecast calls for Rusty's winds to reach at least 115 kts. before landfall, and that landfall could come very near or just east of Port Hedland. Steering currents are weak so there is still room for some track changes.

Near tropical storm force winds are already being felt in Port Hedland and outer spiral bands are affecting a several hundred km stretch of the northwest Australia shoreline.

I don't know what kind of a seawall (if any) protects Port Hedland but this looks like a large, slow-moving cyclone capable of driving a large surge. I hope everyone in the area takes this seriously.
