It's been another extremely busy day for fire crews across the Northwest Territories, as 43 fires are currently burning in the Dehcho region, causing havoc around that area.

People in Jean Marie River are still on an evacuation alert.

Tankers and crews worked through the night and continued on Wednesday to blanket the fire near Jean Marie River. It's burning nine kilometres from the community.

"As long as the wind doesn’t move from the west, they should be OK," said Judy McLinton, from the Department of the Environment and Natural Resources.

Another fast-moving fire forced the shutdown of the N'Dulee ferry crossing between Wrigley and Fort Simpson.

That fire destroyed a trailer and the wooden beams where the ferry is stored during the winter months. The captain of the ferry is credited with saving the staff.

The department of Transportation says for now, the ferry remains closed. The highway from Fort Simpson to Wrigley will be closed for at least the next two days while firefighters work on the fire burning near Fort Simpson.

"As soon as we are able to we are going to resume service and reopen the highway," said Earl Blacklock, from the Department of Transportation.

Fire continues to rage near Wrigley

Meanwhile, crews continue to work on a large fire 20 kilometres northwest of Wrigley.

Forest fire officials are drawing up plans to secure the southeast part of that fire, which is the area closest to the community.

The fires have caused a lot smoke in communities. The territory's Chief Public Health Officer, Dr. Andre Corriveau, is warning anyone affected by smoke to stay indoors and avoid too much outdoor exercise.

"If the smoke is bad enough and even if you're at the top of your health, you're going to damage your lungs because the smoke has fine particles of matter that has toxins, you know they're toxic," said Corriveau.

Some rain is forecast for Thursday afternoon in the Dehcho region. However, a territorial spokesperson said it would take a sustained rainfall over a day or so to really make a difference with the fires.
