A tropical cyclone is developing off WA's north coast and could impact communities in the next few days.
Residents in coastal areas from Whim Creek to Onslow in the Pilbara region have been warned to prepare their homes and family for severe storms.
This includes people in Whim Creek, Roebourne, Wickham, Dampier, Karratha, Mardie, Onslow and surrounding areas.
Tropical Cyclone Narelle is developing 900km north of Karratha and 1070km north north-east of Exmouth, and is moving west south-west at 11km per hour.
The Bureau of Meteorology said the cyclone was expected to intensify in the next few days.
"Gales with gusts to 100km per hour may develop in coastal areas between Whim Creek and Onslow on Friday morning as the cyclone moves closer to the coast, then extends west to Exmouth later on Friday," the bureau said.
"The cyclone is rapidly intensifying and is likely to develop into a severe tropical cyclone as it moves towards the Northwest Cape."
The State Emergency Service advises residents to review their family cyclone plan and know the community cyclone alert system.
Residents have also been reminded to organise an emergency kit with a portable battery operated radio, torch, spare batteries and first aid kit.
