2019 Alberta wildfires instance of wildfire
The 2019 Alberta wildfires have been described by NASA as part of an extreme fire season in the province. In 2019 there were a total of 803,393.32 hectares (1,985,228 acres), which is over 3.5 times more land area burned than in the five-year average burned. The five year average is 747 fires destroying 146,360.08 hectares (361,664 acres). There were 644 wildfires recorded in Alberta. By May 31, 10,000 people had been evacuated, 16 homes, and the Steen River CN railway bridge, had been destroyed.
The department of Agriculture and Forestry's Forest Protection Division reported that by May 31, there were 29 wildfires still burning with nine out-of-control fires. As of June 20, there are a total of 27 wildfires burning with 6 being considered out of control. Of these, five were caused by humans and two by lightning with 20 still under investigation.On May 30, NASA reported that the Terra satellite's Moderate Resolution Imaging Spectroradiometer (MODIS) had collected satellite images of five large "hot spots" on May 29. The fire danger level of four of these five areas—the Steen River wildfire HWF066, the Chuckegg Creek wildfire HWF042, the Peace River area, and the Slave Lake area—was extreme. The fifth, at Wood Buffalo National Park was designated as very high.One fire, described as a fast growing "monster", the Chuckegg Creek Fire HWF042—unofficially known as the High Level fire—had forced the evacuation of 5,000 people in the High Level Forest Area, northern Alberta, and had burned 2,300 km2 (570,000 acres) by May 30 and 237,000 hectares by the evening of May 31.According to Alberta's  Department of Agriculture and Forestry (AAF), the Forest Resource Improvement Association of Alberta (FRIAA) FireSmart program, Alberta communities are under an increased risk of forest fires because fifty per cent of Alberta is covered in forests and because of Alberta's "wildland urban interface" (WUI) —where many communities are nested into forests with buildings and forested areas intertwined. The province's designated Forest Protection Area stretches from north to south of the province along the western border with British Columbia.For purposes of monitoring, the Alberta's wildfire status map subdivides the Forest Protection Area into these areas: Calgary, Edson, Fort McMurray area, Grande Prairie, High Level, Lac La Biche, Peace River, Slave Lake, and Whitecourt.There was smoke from Alberta's wildfires over southern Alberta, southern B.C. Interior and the Lower Mainland, including the city of Vancouver as well as the U.S. Pacific Northwest, reaching as far south as Denver, Colorado. Air quality in cities such as Edmonton and Calgary, reached 10+ out of 10 rating, which is considered to be a severe risk.Historical comparison

In terms of the number of wildfires alone, from March 1 to May 30, the number of fires in 2019 was "slightly under the five-year average" but the "amount of land burned is more than 3.5 times higher."Slave Lake District
Since March 1, 2019 when the wildfire season began in the Slave Lake Forest Area, 818.27 km2 (202,200 acres) were burned and 79 wildfires reported. By May 30 gusty north winds were causing the wildfires in the Slave Lake area to spread.Wildfires SWF049 which started on May 18 is part of the McMillan Wildfire Complex. It was out of control by May 30 having grown considerably on May 29. It has burned 133,952 hectares.The Maria Lake wildfire, SWF069, 13.8 kilometres (8.6 mi) southeast of Trout Lake, was classified as out-of-control on May 30 as it had rapidly grown to 45,845 hectares. It joined McMillan wildfire SWF049. By June 1, the out-of-control SWF069 fire covered 58,579 hectares.
The community of Trout Lake, which is approximately 500 kilometres (310 mi) was issued an emergency alert by May 27, when the fire was 300 hectares in size. On May 31, the evacuation order was issued for Trout Lake as "early-morning southeast winds pushed"  the 211,869-hectare fires—SWF049 and SWF069 (Maria Lake fire)—that make up the McMillan Complex were "rapidly toward the area".
