The text reads, "Canada continues to be threatened by the flames. The 20,000 residents of Yellowknife, the largest city in the Northwest, were ordered to evacuate due to rapidly advancing wildfires."
According to the evacuation order issued by the territory government, residents of N'dilo and Dettah were also directed to evacuate.
On Tuesday, the territory government declared a state of emergency in response to out-of-control wildfires. Wildfires were within 16 km of Yellowknife and could reach the city's outskirts by the weekend if it doesn't rain.
The Northwest Territories is experiencing the worst wildfire season on record, leading to widespread evacuations, loss of personal property and damage to critical infrastructure.
According to the Canadian Interagency Forest Fire Center, there were around 1,000 active forest fires in Canada as of Wednesday, more than 200 of which were in the Northwest Territories.
