Forecasted winds pose biggest wildfire threat amid heat wave: BC Wildfire Service

While scorching temperatures were expected to reach their climax Tuesday in a prolonged heat wave in southern British Columbia, the BC Wildfire Service says the greatest wildfire risk won’t come until later this week.

Fire information officer Sarah Budd says a cold front from the northwest due Thursday will hit the high-pressure system, bringing heat, creating strong winds, dry lightning, and a greater potential for new fire starts.

Budd says it comes as the heat wave that began Sunday and swept across the southern half of the province is already challenging firefighting efforts on active blazes.

B.C. is in the midst of its worst wildfire season to date in terms of area burned, with more than 1,700 wildfires charring about 16,000 square kilometres so far this year.

Budd says the service is prepared for the Kamloops and Southeast fire centres to be the most affected by Thursday’s weather forecast, both for new starts and an increase in fire activity on existing wildfires.

Roughly 370 wildfires are burning in the province, 145 are considered out of control and 11 are classified as fires of note, meaning they are highly visible or threaten people or property.

Late Tuesday, the Regional District of Okanagan-Similkameen issued an evacuation order for 13 properties in Electoral Area “B” and Electoral Area “G” along the Ashnola River in the Cathedral Provincial Park including the Cathedral Lakes Lodge and in the Snowy Protected Area, triggered by the seven-square-kilometre Crater Creek wildfire and the five-square-kilometre Gillanders Creek wildfire.

Officials say an Emergency Support Services Reception Centre has been activated at the Village of Keremeos Victory Hall.

Earlier, there was an evacuation alert put in place for 12 properties affected by the same two nearby blazes, but that has been bumped up to 74 properties in the area along the Similkameen River in Electoral Area “G” from the Village of Keremeos west following Highway 3 for 13 kilometres.

Two communities in the province have already broken 40 C during the heat wave, making them the hottest Canadian locations so far this summer, while more than 30 temperature records have been broken since Sunday.

“That’s obviously fuelling the fire behaviour in those existing fires, and unfortunately, this hot weather is also coming along with relatively high winds,” Budd said in an interview Tuesday. “We could see gusts up to 50 or 60 kilometres per hour today out of the west.”

Bulletins from the weather office show much of the coastal region will return to seasonal temperatures by Wednesday, but central and southern regions of the province will endure the heat a day or two longer.
