The latest map we have was produced on Monday, May 22.
At that point, the fire was estimated to have burned a total of 3,209 hectares.
The map, produced by the Department of Environment and Climate Change, shows the fire has not yet established any form of foothold across the Hay River in the area of the town.
However, the northwest perimeter of the fire does extend through some portions of the Kátł’odeeche First Nation.
The First Nation has confirmed that its band office is among the buildings burned down by the fire, as were a group home for Elders and a number of private homes.
The fire has yet to reach Highway 5, to the south of the current burn area.
On Sunday, the department said air tankers had focused on slowing the spread of the fire toward the highway, which connects Fort Smith and Fort Resolution to the rest of the highway network.
“In the area between the southeast flank of the fire and Hay River there is continuous forest which, in the current conditions, could burn aggressively and cause the fire to take a large run and spread across the river and Highway 5,” the department stated.
“Until lines are built, strengthened, and held across the southern part of the fire, there will continue to be risk to the communities.”
The progress of the fire can also be seen using imagery from the European Space Agency’s Sentinel-2 satellite program.
