During this time, more than a year ago, most of the NWT was burned by wildfires.
NWT Fire posted on Facebook that 257,000 hectares had been burned, close to 100,000 hectares compared to last year.
Last year, only 14,764 hectares were burned, according to the Canadian Enterprise Forest Fire Center.
As of Sunday evening, there had been 96 active fires and three new fires in the past 24 hours.
The wildfire, some 25 miles[40 km]south of Rigley, has spread to 21,873 acres[21,873 ha].
An NWT fire extinguisher has been operating in the area to control the fire.
“This fire will extend the defensive line to the old burned forest area,” the state government said in a statement on Sunday evening.
Both highways and boats have been closed since Sunday night, but now the update warns “may change quickly”.
Anwat Fire posted on Facebook that a wildfire had been contained 10 kilometers from the Hai River.
No communities are currently at risk, the update said.
