A woman has died after her car became submerged in floodwaters as rain-lashed northern Australia braces for another cyclone.
Emergency services responded to reports of a car spotted in the flooded Malbon River at Duchess in Queensland's northwest after 1pm on Thursday.
A 28-year-old woman was found inside the vehicle and declared dead.
The northwest is still reeling from flooding caused by the remnants of ex-Tropical Cyclone Kirrily as the region braces for more wild weather.
A tropical low is set to move southwest towards the Northern Territory, cross the Gulf of Carpentaria coast and move onshore on Friday afternoon.
It has a 40 percent chance of becoming a cyclone on Friday, the Bureau of Meteorology said.
A cyclone warning has been issued for Gulf coastal areas from Port Roper in the NT to Burketown in Queensland's northwest.
The cyclone will be named Lincoln if it forms, the Bureau of Meteorology said.
Winds up to 100kmh and isolated falls beyond 200mm may impact the cyclone warning area, prompting vulnerable residents to be evacuated.
In the NT people have been relocated from the Beswick community south of Katherine, while more than 60 residents have been evacuated from Burketown.
Communities across Borroloola, Groote Eylandt and Mornington Island in the NT are set to be affected by the tropical low even if a cyclone does not develop.
"It's now getting within that closer proximity of land, and probably not quite have enough time (to develop into a cyclone)," the bureau's Patch Clapp said.
"We are seeing severe weather effects regardless of whether it's called a cyclone or not, right along that Gulf coast."
Winds of 75kmh were being felt in the coastal areas of the NT's McArthur River region on Friday morning.
Burketown has already recorded 135mm of rain in the last 24 hours but the bureau said totals of up to 250mm are possible.
The region is bracing for what would be the third cyclone in as many months this season.
Queensland's northwest is still reeling from widespread flooding caused by ex-cyclone Kirrily which crossed the coast just weeks ago.
And Tropical Cyclone Jasper caused record flooding in Queensland's far north in mid-December.
"Many of these areas have had major flooding in the past couple of weeks associated with ex-tropical cyclone Kirrily," meteorologist Angus Hines said of the cyclone warning region.
"In a number of these spots particularly in north Queensland the floodwaters are still easing from the last round of flooding.
"Of particular concern are the Doomadgee and Burketown regions where many roads are closed and communities are still isolated - further flooding is a possibility in those hard-hit regions."
Flood watches are current for Queensland's northwest and for the NT's Daly and Katherine Rivers.
Queensland's southeast has also been lashed with heavy rain on Friday, bringing flash flooding.
There were widespread falls in excess of 100mm overnight, with Rosalie recording 197mm in the last 24 hours.
Brisbane and Bowen Hills have recorded 135mm in the same period, and 148mm inundating Mount Cootha.
The SES has already received about 60 calls for help across the state from midnight on Friday, with almost 50 in the southeast region alone.
