Structures have been destroyed and more than 1000 people remain without power as the cleanup begins in Western Australia following ex-tropical cyclone Narelle.

Heavy rain and destructive winds caused widespread damage across the north, with the towns of Exmouth and Carnarvon particularly impacted.

There have been no reports of serious injury or death.

Premier Roger Cook has announced one-off payments of $2000 for major home damage and up to $4000 for those whose homes have been destroyed.

The payments are to help those impacted secure temporary accommodation, food and clothing, and assist with transport.

"I want to acknowledge the Western Australians that are impacted by this severe, cyclonic event. We've got your back and help is coming," Mr Cook said.

"The worst appears to be behind us."

Structures destroyed and roads closed

Damage assessments are ongoing, however emergency services minister Paul Papalia today confirmed four structures in Exmouth had been destroyed and seven severely damaged, with more expected.

Learmonth Airport, which sustained significant infrastructure damage, will remain closed to commercial flights for at least another week, while 30 pastoral properties have been extensively damaged.

Flooding has forced multiple road closures, including sections of the great northern highway, north west coastal highway and Indian Ocean drive.

Bullara Station in WA's north has also been heavily impacted.

"We've seen vision that confirmed there is a vast amount of water in the region," Mr Papalia said.

"We just ask that people comply with those road closures for their own safety."

As of Sunday morning about 1400 properties in Exmouth in WA's north remained without power, while most outages in Carnarvon had been restored.

Water supply in Exmouth had also been stabilised, with bottled water delivered to the town.

Towns on flood watch

On Sunday a flood watch was issued for catchments in the Gascoyne, Central and Lower West areas, with the potential for localised flooding.

Department of Fire and Emergency Services commissioner Darren Klemm said he was expecting flood waters to reach a moderate level over the next 24 hours and urged people to prepare their homes.

"There's a potential nine to 10 properties that will be at risk, so our personnel will be in touch with the people in Carnarvon," Commissioner Klemm said.

"We really do want people to be patient in terms of the roads. It's going to take a long time for the water to dissipate.

"I think it's weeks in terms of cleanup. We'll get in and get it done quickly."

The premier will fly to the Gascoyne region tomorrow to assess any damage and meet with those impacted by the cyclone.
