Convoys of evacuees stranded by a wildfire raging unchecked in and around the Canadian oil town of Fort McMurray made their way on Friday through the heart of the devastation on the only highway out of the region, passing through the city's charred ruins.

Wind-whipped flames roaring through heavy timber and brush parched by a spring heat wave have engulfed nearly 250,000 acres (101,000 hectares) in western Canada's energy heartland since erupting on Sunday.

The blaze, the largest of 40 wildfires burning across the province of Alberta, has forced some 88,000 residents, virtually the entire population of Fort McMurray, to flee for safety, and has threatened two oil sands production sites south of the city.

The full extent of property losses in Fort McMurray, located about 270 miles (430 km) north of the provincial capital Edmonton, has yet to be determined, but authorities said some 1,600 structures were believed to have been destroyed. One analyst estimated insurance losses could exceed C$9 billion ($7 billion).

Earlier in the week most evacuees headed south by car on Alberta Highway 63, the only land route out of the area, in a slow-moving exodus that left many temporarily stranded on the roadside as they ran out of gasoline.

But other residents who initially sought shelter in oil camps and settlements north of the city found themselves cut off in overcrowded conditions. They were forced on Friday to retrace their route back through Fort McMurray on Highway 63 as flames continued to spread.

Evacuees in some 1,500 vehicles began making the 30-mile (50-km) trip at 4 a.m. in groups of 50 cars.

"It reminded us of a war zone," said Marisa Heath, who spent 36 hours in her truck on the side of the highway with her husband, two dogs, a cat and seven kittens. "Eerie. All you could see was cement foundations of houses."

Helicopters hovered overhead watching for flames, and police set up emergency fuel stations along the highway to keep the line of cars moving. They headed toward safety south of Fort McMurray in towns including Lac La Biche, 180 miles (290 km) away, and Edmonton farther on.

The convoys were halted briefly around midday due to heavy smoke, but officials said the majority of vehicles had already passed through town by then.

Authorities planned to airlift about 8,000 of the 25,000 evacuees who were initially chased north of Fort McMurray.

The crisis brought a message of sympathy from Pope Francis, who expressed sadness and said he was praying for the displaced, especially children, and for those battling the fires.

OIL PRODUCTION CUT

About a third of Canada's oil production has been shut by the conflagration, according to a Reuters estimate.

South of Fort McMurray, CNOOC Nexen's Long Lake oil sands facility and Athabasca Oil's Hangingstone project were in danger of being overrun by flames, emergency officials reported. Both facilities have been evacuated.

BP Plc's Canadian unit has declared a force majeure resulting in the reduction of available Western Canadian Select crude, among other Canadian grades, according to two trading sources familiar with the matter.

There have been no known casualties from the fire itself, but fatalities were reported earlier this week in at least one car crash among the evacuees.

Winds were pushing the leading edge of the main fire to the northeast into forested areas, and away from town on Friday, authorities said, though parts of the city were still in flames.

As of Friday, more than 1,200 firefighters were arrayed against blazes across Alberta, backed by more than 100 helicopters and over two dozen airplane tankers equipped to drop water and fire-retardant chemicals on the flames.

But the sheer magnitude and intensity of the Fort McMurray fire mostly defied all efforts to contain it.

Cecil Dickason, a Fort McMurray resident who was part of the convoy, said the battered city looked "awful." Others described the city as dark and smoke-filled, pockmarked with charred and abandoned vehicles and roadside spot fires.

Entire neighborhoods were reduced to ruins, but most evacuees fled without knowing the fate of their own homes. The majority got away with few possessions, some forced to leave pets behind.

Bill Glynn, who took part in the convoy, told the Edmonton Journal newspaper that he traveled through smoke so thick he lost sight of the car in front of him as they crept through the city.

"It was scary," evacuee Sarah Babstock told the newspaper. "We came through with clothes over our mouths so we could breathe."

In a press briefing on Friday, Alberta Premier Rachel Notley said damage to Fort McMurray was extensive.

"The city of Fort McMurray is not safe to return to, and this will be true for a significant period of time," she said, adding that officers of the Royal Canadian Mounted Police would secure and protect what was left of the town.

The Alberta government has approved emergency funding for wildfire evacuees and will be giving out C$1,250 ($966) per adult and C$500 ($387) per dependent.
