WA Police say there have been no reports of injury from Cyclone Anika as it passes through the North Kimberley.
Anika made landfall at 8 o'clock last night as a category-two system and was later downgraded to category one.
It passed over the town of Kalumburu — home to around 400 people — but left only minor structural damage.
Senior Sergeant Kevin Hall, officer-in-charge at Kalumburu, said it was a "pretty rough night", with wind gusts of up to 100 kilometres per hour.
"We haven't had any report of injury to people, so that's a good thing, and I've checked in with our friends up at Far Away Bay and also out at Honeymoon, and they're all safe so that's the main thing.
"Fortunately it's only some minor structural damage to a few houses. A lot of trees are down across the internal roads of the community.
The Bureau of Meteorology said Kalumburu recorded around 250 millimetres of rain in the 24 hours to 9am today.
Dave Corstorphan, who has lived in the town for nearly two years, said the wind picked up for six or seven hours before easing around 4:30am.
"It just kept getting more and more intense and then we just had that lull, so we can probably expect the winds to pick up again, or they are picking up, but certainly get a lot stronger before things get calmer again."
Senior Sergeant Hall said people should remain cautious while a red alert was in place.
"We're obviously encouraging people to remain inside and not go out for a look around just yet. We are expecting more rain in the next couple of hours."
There is also a yellow alert for the area between Kalumburu, Mitchell Plateau and Wyndham. A blue alert is in place for Mitchell Plateau to Kuri Bay.
BOM duty forecaster Luke Huntington encouraged people to prepare.
"People in those areas should definitely stay up to date with the latest weather warnings and forecasts.
The weather bureau is also advising of the risk of flooding in the North Kimberley, with heavy rain forecast for the Berkeley River to the Prince Regent River into Monday and then shifting towards Derby and Broome.
For the remainder of Sunday, Anika is due to continue across land towards Kuri Bay, dropping below the strength of a tropical cyclone.
"It will continue to track south-westwards during today and then probably pop out off the west-northwest Kimberley coast once again around Kuri Bay early on Tuesday morning," Mr Huntington said.
"Then it's due to keep going offshore and redevelop back into a cyclone once again."
