Heavy rain will continue to fall on far north Queensland ahead of a possible cyclone as the search for a woman missing in floodwaters resumes.

The 34-year-old has not been seen since walking into fast-flowing Wallaby Creek at Rossville, north of Cairns, as she travelled home around 6pm on Thursday evening.

Authorities started searching for her yesterday after friends reported her missing.

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.

It comes as northern Queensland braces for a potential cyclone in the coming days if a monsoon trough moving south towards Australia gets stronger.

The cyclone could form around the Cape York Peninsula tomorrow
