Commander Bruce Porter said police travelling to Beswick via helicopter observed a vehicle stranded in a floodway on Dook Creek, 4km west the community.

 It is believed at this time that the vehicle with five occupants became stranded and the woman has drowned. 

"This is the second person who has been washed away in a flooded creek since Christmas. Again, I urge people to avoid taking unnecessary risks on the roads and avoid driving into flood ways," Commander Porter said.

Investigations are continuing with a report for the coroner to be provided.

Police and NT Emergency Services are continuing to search for a 28-year-old man who went missing in floodwaters near Peppimenarti on Friday afternoon. 

Evacuations from the Daly River region for all people of the community that required assistance were completed on Sunday.

The Foskey Pavilion, at the Darwin Showgrounds, was expected to receive just under 470 evacuees with a number of activities being planned, particularly for the children. 

Region two controller Commander Bruce Porter said the tropical low had moved east as predicted.

“The Bureau of Meteorology has cancelled its cyclone watch, but a severe weather warning is now in place for the same area, Port Roper through to the Queensland border,” he said.

“I continue to urge everyone to exercise extreme caution on the roads and to consider the necessity of their travel plans. Anyone setting out should check the road report website through Secure NT before they set out to drive anywhere.

“The last thing we want is for anyone to become an unnecessary statistic. Your safety is our priority.”

Water levels across the Arnhem, Carpentaria and Gregory districts are being closely monitored, including the Waterhouse, McArthur and Victoria Rivers.

The Katherine River at Gorge Road is the only section where a minor flood warning has been cancelled.

Katherine Town Council infrastructure along the river corridor - including the hot springs, boat ramp and Knotts Crossing - remains closed.
