The fire, which started on May 1, spread so quickly that the community’s inhabitants barely had time to leave and whole neighbourhoods were destroyed.
“This is great firefighting weather, we can really get in here and get a handle on this fire, and really get a death grip on it,” Alberta fire official Chad Morrison said.
The wildfire scorching through Canada’s oil sands region in northeast Alberta had been expected to double in size, but light rains and cooler temperatures helped hold it back.
The temperature, which reached a high of 17°C on Sunday, was expected to cool further, with Environment Canada forecasting a 40% chance of showers in Fort McMurray.
Cooler temperatures were expected from today through to Friday after last week’s record heat. Still, much of Alberta is tinder-box dry after a mild winter and warm spring.
Alberta’s government estimated that the fire had consumed 161,000 hectares.
Officials made clear it was too early to put a timeline on getting thousands of evacuees camped out in nearby towns back to Fort McMurray soon.
The city’s gas has been turned off, its power grid is damaged and the water is undrinkable.
Alberta premier Rachel Notley said recovery efforts had begun, with 250 employees from power company ATCO working to restore the power grid and assess gas infrastructure.
Fort McMurray is the centre of Canada’s oil sands region. About half of the crude output from the sands, or 1m barrels per day, has been taken offline, according to a Reuters estimate.
prices jumped almost two% in trading as Canada’s fire contributed to tightening supply.
The inferno looks set to become the costliest natural disaster in Canada’s history. One analyst said insurance losses could exceed C$9bn.
Nearly all of Fort McMurray’s 88,000 residents have escaped the fire safely, although two people were killed in a car crash during the evacuation.
In his now regular evening message, Fort McMurray fire chief Darby Allen sent condolences to the families of the two teenage cousins in the crash. One of the victims, 15-year-old Emily Ryan, was the daughter of a fireman in the city.
