Weekly Synopsis

Canada has recorded 4,429 fires so far this year, which have burned 2,473,318 ha. Over the past week, the largest area burned was in the Northwest Territories, who reported over 550,000. British Columbia had over 300,000 ha burned over the past week. Saskatchewan (38244 ha) and Manitoba (30264 ha) had the next most area burned over the past week. Lightning accounted for about 51% of the new fires. While seasonal fire occurrence is approximately 80% of the 10-year average, the area burned increased by nearly 1 million hectares this week and is now above the 10-year average (108%).

The ridge that stalled over British Columbia at the end of July has gradually moved eastward and compressed with the help of surging Pacific air. It now sits between western Ontario and the western Arctic islands. West of the ridge axis, temperature has cooled to seasonal values, and cloud and humidity have increased. A weak low crossing northern British Columbia will provide some shower and thundershower activity to central and northern British Columbia and Alberta. The leading edge of the Pacific air will generate showers, thundershowers, and likely a few more fires between extreme western Ontario and western Nunavut. This frontal band connects to a stronger system in the central Northwest Territories, where substantial rain will fall north of Great Slave Lake and east of the Mackenzie River. Eastern Ontario and western Quebec stay dry, but with low fire danger after recent rain. The responsible low is moving through Quebec, maintaining showers and low fire danger through eastern Quebec and northern parts of the Atlantic Provinces. Patchy areas in New Brunswick remain dry and prone to fire.

In British Columbia, open fires and campfires are prohibited across the province. Forest use is restricted in areas near the Big Bend Creek, Tatelkuz Lake, Lucas Lake and Chedakuz Creek wildfires southwest of Vanderhoof, as well as the Cariboo Forest District.

Off-road vehicles for recreational purposes on Crown land will be prohibited throughout the Cariboo Fire Centre, Kamloops Fire Centre and Southeast Fire Centre. In addition, all on-highway vehicles must remain on defined road surfaces.

The weather pattern in Canada remains more variable than in recent weeks. This brings a return to seasonal temperatures, higher humidity, and increased rainfall to much of the country. Southern parts of the western provinces remain dry and susceptible to fire starts; however, fire activity in Yukon and the northern Northwest Territories will likely continue to dwindle with repeated bands of rain.

A Pacific storm crossing western Canada Friday and Saturday (August 18-19) will likely bring a fast-moving cold front, thundershowers, brisk west to northwest winds, potential for new fires, and quick fire growth. Following this, a ridge appears to build over western Canada early in the week of August 20, returning warm, dry, and calmer weather to much of the west; however, the ridge appears likely to move eastward late in the week. Eastern Canada appears to receive regular rainfall, limiting fire activity.
