Two neighboring provinces in Canada’s prairies have declared states of emergency as dozens of wildfires have flared up and grown out-of-control, displacing thousands of residents.

Scott Moe, the premier of Saskatchewan, issued the emergency order on Thursday, one day after his peer, Wab Kinew of Manitoba, did the same.

Fifteen communities have been evacuated across northern Saskatchewan, a rural region home to several Indigenous reserves.

“I do fear things are going to deteriorate with the weather that we have ahead of us,” Mr. Moe told reporters at a news conference on Thursday. The forecast showed no signs of much-needed rain, while warm overnight temperatures and expected high winds could accelerate the flames.

Canada’s wildfire season, which tends to be the most active from May to September, had a grim start in Manitoba earlier this month with the deaths of two people who were trapped and killed in a small western town before they could evacuate.
