There are no wildfire management agencies at Agency Preparedness Level (APL) 5, however Nova Scotia is at Agency Preparedness Level (APL) 4, British Columbia, Alberta, Saskatchewan, Manitoba and New Brunswick are at level 3, and all other agencies at 2 or lower. At the time of this report, there are domestic and international personnel, aircraft, and fire fighting equipment being mobilized through CIFFC.

The United States is at preparedness level 3, indicating mobilization of resources is required to sustain incident management operations in the active areas.

The number of fires is average for this time of year, but the area burned to date is significantly more than the 10-year average. There were 196 number of fires started by lightning over the last week.

Prognosis

Another strong ridge sitting over British Columbia will gradually move east, continuing the warmth and drying trend for the next week. Eastern Canada will remain under the influence of an upper trough which will bring rain to much of Ontario, Quebec, and Labrador. The Maritime Provinces will remain dry most of this week.

Temperatures in British Columbia and the prairies remain warm although smoke from fires in the Northwest Territories may hold temperatures back slightly in the prairies. Near daily thunderstorm activity is expected over higher terrain. Concentrated over southern and western parts of the province. Riding will also bring in a brief period of warm temperatures (low 30s possible) in southern British Columbia from September 4-7.

Cooler air with occasional showers will dominate Saskatchewan and Manitoba on the east side of this ridge for a few days until it moves further east late in the week.

Continued dry conditions are likely in southern Yukon and the southern Northwest Territories until at least the September 6-7 weekend. A weak low-pressure system will spin up over southwestern Northwest Territories. While this system is not likely to bring much precipitation outside of some showers, it is likely to bring variable and gusty winds.

A few isolated showers or thunderstorms are possible, especially over higher terrain. With the recent warmth and dryness, lightning strikes could continue to ignite fires in western Canada, although the lack of atmospheric moisture over the prairies suggests that lightning activity will be minimal.

The Atlantic region will remain dry into the weekend. On both September 7 and 9 some showers are likely to fall over Nova Scotia, PEI, and Newfoundland. Uncertainty is higher over New Brunswick and the province may continue to be dry.
