Fires of note

As of August 8, British Columbia has 11 priority fires, of which six have triggered evacuation orders. The 12,000-hectare Snowy Mountain Fire, a potential threat to Cawston and Keremeos, is now 40% contained. In the north, the residents of Telegraph Creek have been evacuated because of the Alkali Lake Fire. There are a total of 456 fires burning in BC, of which 255 are out of control, and a total of 3000 personnel supporting wildfire operations. Ontario has six priority fires, only one of which is out of control. Rain has slowed fire activity across most of the province. Firefighters have made good progress on the 11,000-hectare Parry Sound fire, which caused the evacuation of Key Harbour and Henvey Inlet almost three weeks ago. Parks Canada reports one priority fire, the Wardle Fire in Kootenay National Park. Highway 93 is closed and Kootenay Park Lodge has been evacuated.

Interagency mobilization

The national preparedness levels are at 5 in both Canada and the United States, indicating that available fire control resources are insufficient for the current level of fire activity. British Columbia is at level 5, Ontario at level 4, and Parks Canada at level 3. Personnel and equipment from across the country, as well as USA, Mexico and Australia, have been mobilized to Ontario and British Columbia.

Weekly Synopsis

Canada has recorded 5,610 fires so far this year, which have burned 865,466 ha. New fire starts totalled 634 in the last week, with 431 (68%) of these new fires due to lightning. Area burned over the last week totalled over 68,000 hectares. The number of fires so far this year is above the 10-year average (117%), but the area burned is well below average (39%).

Smoke from fires in western North America continues to affect air quality between British Columbia and Saskatchewan, prompting advisories by Environment Canada. Heat advisories also cover much of this region for the next few days as a Pacific storm off the Pacific Northwest USA coast and a ridge centred over the desert states drive hot air into Canada. Scattered showers and thundershowers continue throughout the Yukon and Northwest Territories with some moisture clipping extreme northwestern British Columbia. Weak troughs centered over Ontario and Labrador are providing instability and scattered showers or thundershowers in those regions.


Hot and dry weather grips the western half of the country until the weekend when a Pacific storm begins to move through the southern halves of British Columbia and Alberta. This is an important event with wind potentially giving high ignition indexes and spread rates, and instability likely generating widespread thundershowers. Erratic fire growth and new starts are likely in southern British Columbia, and central and northern parts of all provinces east to Quebec over the next week. The most intense rains are likely to fall in higher mountains and the west-central Alberta foothills. The abundant fire activity around the Prince George region of British Columbia will likely remain on the fringe of the rain area. Weak disturbances trekking through eastern Canada will initially provide showers or thundershowers, but a general warming and drying trend appears to set in during the weekend, giving a general rise in fire weather indexes.
