Pilbara set to dodge Cyclone Narelle's fury

Coastal communities in the Pilbara can breathe a sigh of relief with Cyclone Narelle expected to steer clear of Western Australia's coast on Sunday.

"Severe tropical Cyclone Narelle is expected to move to the south southwest and pass well west of the Northwest Cape on Sunday," the Bureau of Meteorology said.

A cyclone warning is still in place for coastal areas from Onslow to Cape Cuvier, including Exmouth, while the warning from Mardie to Onslow has been cancelled, in the latest BOM forecast.

This satellite image from earlier in the week shows Cyclone Narelle approaching WA's north-west coastline.

A cyclone watch continues for coastal areas from Cape Cuvier to Denham including Carnarvon.

Gales with gusts to 100 kilometres per hour may still develop in coastal areas between Onslow and Exmouth later Saturday, extending south to Cape Cuvier on Sunday.

If the cyclone takes a track closer to the coast than expected then gales may extend south to Denham late on Sunday or Monday.

The severe tropical cyclone, which upgraded to a category four cyclone on Friday morning, was 435 kilometres northwest of Exmouth and 720 kilometres north northwest of Carnarvon and moving southwest at 9 kilometres per hour at 8am on Saturday.

There is a blue alert for coastal and island communities, who should be taking precautions, from Mardie to Coral Bay including Onslow and Exmouth.

Thunderstorm activity in western parts of the Pilbara could be squally with isolated heavy falls.

Tides along the west Pilbara coast are likely to rise above the normal high

tide mark with flooding of low lying coastal areas possible. Higher than normal tides should extend along the west coast overnight tonight and continue into early next week.
