Tropical Cyclone Narelle appears to have spared Exmouth from destructive weather, as it continues to move down Western Australia's Pilbara coast.
Narelle was downgraded to a category four storm overnight, and was most recently located about 330 kilometres west north-west of Exmouth.
A blue alert has been cancelled for communities between Onslow and Exmouth, while people living between Coral Bay and Denham are being asked to stay alert
Exmouth's State Emergency Service Manager, Russell Levien says the only report of damage was an unmanned tugboat that sank at its cyclone-protected moorings in Onslow.
"An EPIRB went off yesterday," he said.
"We found out this morning it was a small tug boat that sank on its moorings in Onslow.
"That's all we know, how it sank, not sure."
