A woman is missing in floodwaters in far north Queensland after walking into a fast-flowing river on her way home.
The 34-year-old has not been seen since entering Wallaby Creek on River Road at Rossville, north of Cairns, around 6pm on Thursday.
Authorities started searching for her on Friday morning after friends reported her missing.
Police and emergency services will continue the search to dark before resuming on Saturday.
Parts of the far north region have received more than 400mm of rainfall in the past week, with flood warnings in place for the Daintree and Mossman rivers.
A flood watch has been issued for areas north of Cardwell, which has had its wettest December on record with 1031mm.
Cairns and Cooktown have recorded their wettest December since 1975, while at Innisfail it's the wettest December since 1950.
"There has been considerable weather up on the north tropical coast and into the peninsula district over the last few days with some very heavy rainfall and some moderate to major flooding," the Bureau of Meteorology's Gordon Banks told AAP on Friday.
Northern Queensland is also set to be hit by its first cyclone of 2019, as a monsoon trough to the north of Australia continues to head south.
If the unstable trough develops into a tropical low over water a cyclone watch could begin for the Cape York Peninsula as early as Saturday morning.
Mr Banks said the region could be again inundated with rain if the tropical low develops as the bureau expects it to.
"It's all about to ramp again with the monsoon trough coming down over the peninsula and tropical lows developing over the next couple of days," Mr Banks said.
"We should see that low developing through the weekend and ... there is the potential for it to develop into a tropical cyclone as early as late Sunday or early Monday morning."
