Forest Fires in Canada

5 July 2000


The Canadian Interagency Forest Fire Centre (CIFFC) distributes timely information about forest fires in Canada. The current fire situation for 4 July 2000 can be summarized as follows:

over the last 24 hours: 31 fires for 6.640 ha season summary: 2,464 fires for 69,782 hectares

 

According to the National Forest Fire Situation Report of 28 June 2000 (updated every Friday), due to continuing cool wet weather across much of the country, the weekly number of fires continues to be below average and the area burned to date has dropped to less than 1/10 of normal. To date, Manitoba and B.C. account for over 55% of the total area burned. Risk of fire has increased slightly over the last week in Saskatchewan and Alberta.
Although risk of fire remains relatively low across most of the country, dry conditions have continued or have been developing for the last week The Buildup Index remains high for most of western and northwestern Canada. Areas to watch for are Saskatchewan, Alberta and the Maritimes.

The Fire Monitoring, Mapping, and Modelling (FireM3) is a collaboration of the Canadian Forest Service and the Canada Centre for Remote Sensing. Through the Map Link at the FireM3 web site you can access daily hotspot images. An Internet Map Server, which is like a simple GIS running on the host computer, allows you to zoom in on any fire or other area of interest and view the image and map data at full (1km) resolution. You can also click on any fire and get information about that fire.

The Canadian Forest Fire Weather Index (FWI) System is a part of the Canadian Wildland Fire Information System and consists of six components that account for the effects of fuel moisture and wind on fire behavior. The first three components are fuel moisture codes and are numerical ratings of the moisture content of litter and other fine fuels, the average moisture contentof loosely compacted organic layers of moderate depth, and the average moisture content of deep, compact organic layers. The remaining three components are fire behavior indexes which represent the rate of fire spread, the fuel available for combustion, and the frontal fire intensity; their values rise as the fire danger increases. For futher information please see the Summary Information.

The Canadian Forest Fire Behavior Prediction (FBP) System is an other part of the Canadian Wildland Fire Information System and provides quantitative estimates of head fire spread rate, fuel consumption, fire intensity, and fire description. With the aid of an elliptical fire growth model, it gives estimates of fire area, perimeter, perimeter growth rate, and flank and back fire behavior. For futher information please see the Summary Information.

The Saskatchewan Daily Forest Fire Situation Report (4 July 2000) is listing all forest fires currently burning in Saskatchewan and their current status. This report also gives statistics on the total number of fires to date. The whole report and further information can be accessed at the fire management website of “Saskatchewan Environment and Resource Management” (SERM).

fires burning in the province today: 33 extinguished in the past 24 hours: 16 new fires: 3 total number of fires to date this year: 285 total up to this date last year: 328 five year average for this date: 372

 

British Columbia Forest Service Wildfire Report (30 June 2000):
Forest fire danger increases
VICTORIA – A warming trend early this week has resulted in a moderate increase in the fire danger rating across the province. The warmer weather is expected to continue through the weekend, along with westerly winds. Burning restrictions are in place in the southeast, Kamloops Okanagan area and coastal region in response to this warming and drying trend, and fire centres are anticipating more wildfire starts.
So far this year, 300 wildfires have been reported in the province, almost 90 per cent of them caused by human activity. With cooler temperatures and the high moisture levels, however, most of these fires have been quickly contained.
At the same time last year, 299 fires had been reported. The Forest Service responds to an average of 2,800 wildfires during an annual fire season.
Ninety-four per cent of these fires have been contained at less than four hectares.

Wildfire Statistics Report, 4 July 2000
