CYCLONE Narelle is no longer a threat to WA communities but residents have been warned to avoid potential hazards caused by storm damage.
The all clear has been given to the state's north in and near Exmouth and Coral Bay.
However, Coral Bay residents should remain cautious with strong winds still impacting the area.
The Bureau of Meteorology said at 2.30pm today the category three cyclone was about 355km west of Exmouth and 440km northwest of Carnarvon, and moving south southwest at 14km/h.
It is expected to continue south southwest and not come closer to the coast before weakening.
The bureau says the cyclone is also unlikely to produce gales on the coast, although a severe thunderstorm warning has been issued for Sunday afternoon and evening for parts of the Gascoyne and Central West districts, including coastal areas between Cape Cuvier and Northhampton.
Tides along the west Pilbara coast and down the west coast are likely to rise above the normal high tide mark with flooding of low lying coastal areas possible, the bureau said.
Road users have been advised gusty winds, thunderstorm activity and high tides may affect driving conditions, and road conditions could change.
"Please approach all floodways with extreme caution, obey road closure signs and do not drive into water of unknown depth and current,'' the State Emergency Service advises.
"If driving through heavy rain, please slow down and turn your lights on, or if visibility becomes poor, pull over and park until it passes.''
Authorities said there was no damage to homes or other infrastructure during the cyclone threat.
Incident management teams in Karratha and Carnarvon have both begun demobilising.
Earlier today
A blue alert was current for people in or near coastal and island communities from Exmouth to Coral Bay and a cyclone warning was current for people in or near Exmouth to Denham.
But a cyclone warning was cancelled for people in or near Onslow to Exmouth.
The Bureau of Meteorology said that at about 11.30am today the category three cyclone was estimated to be 335km west north-west of Exmouth and 460km north north-west of Carnarvon, and was moving south south-west at 15km/h.
The cyclone is expected to continue to move south south-west and will pass west of the Northwest Cape today.
If the cyclone moves on a track that brings it closer to the coast, then gales with gusts to 100km/h may develop in coastal areas between Exmouth and Cape Cuvier during Sunday and may extend south to Carnarvon and Denham late today or early tomorrow, the bureau said.
Tides along the west Pilbara coast and down the west coast are also likely to rise above the normal high tide mark with flooding of low lying coastal areas possible.
The State Emergency Services is continuing to monitor the situation while incident management teams in the Pilbara have begun demobilising and will continue to do so throughout the afternoon.
Teams in the Midwest Gascoyne region remain active as the cyclone travels down the coast.
Meanwhile, residents living near or between Cape Cuvier, Carnarvon, Denham, Kalbarri, Northampton and Meekatharra have been warned to get ready for severe thunderstorms developing from late Sunday morning and continuing into the evening.
WA police told AAP today that no emergency incidents had been reported as a result of Cyclone Narelle.
