A newly discovered forest fire burning near the mouth of the Sixty Mile River is now an estimated 660 hectares.

As well, it's expected to grow further today with warm temperatures in the forecast, perhaps touching the 30-degree mark.

Believed to have been sparked by a lightning strike, it remains about 50 kilometres south of Dawson City, and does not currently pose a threat to the community.

"This afternoon, as the temperature increases, the fire will be very active and once again be visible to those in Dawson City and the surrounding areas,” said duty officer Lorne Harris of Yukon Wildland Fire Management.

"It remains two kilometres from the closest value, that being a small cabin, and sprinkler kits have been put in place.

"This fire is very visible from West Dawson, the Top of the World Highway and the Dome, and the Yukon Fire Centre has been getting a number of calls from the public.”

A mining camp located at 10 Mile Creek remains 10 kilometres west of the blaze.

Fire officials have been in regular communication with both the mining camp staff and the cabin owner and will continue to monitor the situation closely.

A 16-hectare fire is currently burning approximately 110 kilometres west of Beaver Creek in the wilderness zone, with no values at risk.

Meanwhile, a large fire burning in Alaska remains very active. It's expected to blow smoke into Beaver Creek today.

The fire remains 15 kilometres from the Alaska/Yukon border and does not pose a threat to the community.

In Mayo, the large fire near Ethel Lake is now an estimated 4,200 in size.

Firefighters have been focusing on the northwest corner of the blaze in an effort to prevent it from spreading towards the identified values. That work has been successful and will continue today.

Given the current conditions, the public is asked to only burn if absolutely necessary and to ensure any fires lit are completely extinguished and cold to touch before leaving the area.

The public is also reminded that burning permits, now mandatory in the territory, will be suspended whenever the fire danger rating is moderate, high or extreme.
