Firefighters kept wildfires at bay near the capital of Canada’s Northwest Territories as well as a threatened city in British Columbia, though no one claimed victory as forecasters warned that drier and windier weather was coming.

For Saturday at least, the weather was milder, providing some help for fire teams battling to contain the flames of Canada’s worst fire season on record that destroyed structures, fouled the air with thick smoke and prompted evacuation orders for tens of thousands of residents.

Officials said a huge wildfire again had been kept from advancing closer than 15 kilometers (9 miles) to Yellowknife, the capital of the Northwest Territories that was left virtually empty when nearly all of its 20,000 residents fled for safety.

“We’re by no means out of the woods yet,” Mike Westwick, wildfire information officer for the city, told The Associated Press. “We still have a serious situation. It’s not safe to return.”
