Hot and dry weather is spawning dozens of new wildfires across Alberta, with blazes threatening more than 400,000 barrels a day of Canada’s oil production.

In the past 24 hours, 47 new fires emerged in the province, most of them south of the unofficial oilsands capital of Fort McMurray, said Kai Bowering, spokeswoman for Alberta Wildfire. The arid conditions are expected to persist for the next 24 hours, making it easier for the blazes to spread, she said.
