A tropical low bearing down on Queensland is no longer expected to reach tropical cyclone intensity.
The low, which strengthened overnight, was bringing winds of up to 55km/h, with gusts up to 85km/h, on Wednesday afternoon.
It was being tracked as it moved east at 15km/h in the Gulf of Carpentaria.
While the Bureau of Meteorology cancelled a cyclone warning between Karumba and Cape Keerweer, flood warnings remained in place for a host of waterways including the Ross, Georgina, Diamantina and Bohle Rivers, along with Eyre Creek.
"The low has moved rapidly eastwards during the day and is now close to the coast," forecasters said.
