Alberta officials issued an expanded order Tuesday, according to the report.

Nearly 53,000 people had moved to safer ground, authorities said.

Extremely high temperatures and low humidity fueled the blaze, leaving firefighters battling "explosive" conditions, CNN reports.

"All our efforts to control and contain the fire were challenged by this extreme fire behavior," said Bernie Schmitte, the forestry manager.

"Efforts were also hampered by smoke conditions. Basically fire behavior was beyond all control efforts," he said.

No injuries or casualties have been reported.
