TOURIST towns in WA's north-west menaced by tropical cyclone Carlos this week have finally been given the all-clear as the storm system continued out to sea.
The Fire and Emergency Services Authority this morning lifted a red alert notice for the popular Ningaloo Reef towns of Exmouth, Coral Bay and the Pilbara and Gascoyne regions.
FESA spokesman Allen Gale said wind and storm surge dangers had now passed, but residents were cautioned to take care to avoid the dangers caused by storm damage.

Mr Gale said people should also be wary of fallen power lines and trees, broken water and sewerage lines, loose roof sheeting and other material.
Horizon Power said approximately 250 customers had been left with partial power supplies in Exmouth and emergency crews were working to restore full power services.
While gale-force winds were no longer expected to affect the mainland, people on the west coast south of North-West Cape, including residents of Carnarvon, were warned tides would be higher than normal and may rise above the normal high tide mark.
Marble Bar residents have been warned to use boiled tap water or bottled water due to risk of contamination of the local water supply.
Heavy rainfall had eased over western Pilbara coastal streams with only moderate falls likely this morning.
At 5am today, Carlos was estimated to be 290 kilometres west north-west of Carnarvon and 355 kilometres west south-west of Exmouth and moving west south-west at 19km/h.
The system is now over open water and moving away from the coast. Carlos was likely to intensify during the day as it moves towards the south-west.
