[1/2] A Sky crane helicopter dumps water on the Eagle Wildfire Complex near Fox Creek, Alberta, Canada May 19, 2023.
Record-high temperatures and lack of rain this year have led to widespread fires burning nearly 830,000 hectares (2 million acres) of land in Alberta, about 10 times the size of the province's largest city, Calgary, according to Alberta Wildfire.
"We will all be on high alert this weekend," Christie Tucker, information unit manager at Alberta Wildfire, said on Friday.
The wildfires have tested Alberta Premier Danielle Smith's disaster management skills ahead of a provincial election on May 29.
Some 275 houses, businesses and other properties had been damaged, while more than 10,000 people remained evacuated by Friday, according to Alberta government officials.
