A Kimberley cattle station has recorded Western Australia's highest daily rainfall total in more than a century.

Country Downs, around 90 kilometres from Broome, recorded 843mm as a tropical low swept across the region this week.

The station received 652.2 millimetres in the 24 hours to 9am Tuesday — the second-highest figure ever recorded in the state. 

It fell just shy of the 747mm recorded in 24 hours in the Pilbara town of Roebourne on April 3, 1898.

Pastoralist Nikki Elezovich was relieved after a dry start to the wet season.

"We had 17mm in December; that's quite unprecedented," she said.

Ms Elezovich said the heavy rainfall had moved a lot of topsoil and knocked over fencing and trees across the property, but it would be several days before they could leave the homestead to assess the full extent of the damage.

"We would have preferred that 650mm, maybe over three months, but you cannot control that," she said.

80,000 lightning strikes

The township of Broome has also faced a massive clean-up, recording 564 millimetres in the 48 hours to 9am Tuesday and a staggering 80,000 lightning strikes in a 24-hour period.

"About 30,000 of those were cloud to ground [lightning] strikes, so strikes hitting the ground," said the Bureau of Meteorology's Daniel Hayes.

A moderate flood warning remains for the Fitzroy River, and several roads have been closed, including parts of the Gibb River Road, Cape Leveque Road and the Great Northern Highway between Fitzroy Crossing and Halls Creek.

Phil Hams at Gogo Station, nine kilometres from Fitzroy, said the inconvenience was a small price to pay for pastoral stations on the catchment.

"The countryside was looking pretty good, but now it's certainly got a hell of an advantage from this rain," he said.

"Fitzroy Crossing has had 265mm since Friday. On top of that, for the month of January, we've had about 450mm at the stations, so you can imagine the benefits of that.

"We've got a serious amount of water coming down the river system. It hit almost 500,000 megalitres a day.

The Bureau's senior hydrologist, Michael Salinas, had another way to describe the flow of water.

"[It]'s equivalent to 3,000 Tesla Model 3s flowing every second down Fitzroy River Crossing," he said.
