Nearly 400 wildfires are burning across B.C. as of Saturday morning, according to the B.C. Wildfire Service (BCWS).
In a report Saturday, the service says a period of hot and dry weather combined with lightning activity is driving new wildfire starts and could intensify existing fires.
The service is forecasting a significant chance of lightning for the southern Interior on Saturday afternoon.
It says more than 1,700 personnel are responding to fires across B.C., and more than 260 wildfires have been declared out in the preceding seven days, as of Saturday morning.
BCWS fire information officer Sarah Budd told CBC News Friday August is usually the most intense month for wildfires in B.C.
On Saturday, Environment Canada issued several heat warnings for regions in the B.C. Interior, as well as Fort Nelson in the northeast.
The majority of the wildfires active in the province are caused by lightning, according to the service. Budd said the wildfire service expects small fires started by lightning, that cannot yet be detected, will become visible as the humidity continues to drop.
“You might see a lightning strike. Then [a fire] will smoulder slowly, and as conditions warm and dry — often, wind is what does it — that will really kick those kinds of fires up,” she said. “When we’re getting more oxygen into the fire, those fires pop up and become visible to our scanning.”
Budd said the BCWS expects hot and dry weather to continue over the weekend.
Campfires banned in most of B.C.
The hot and dry weather has led the BCWS to reinstate its ban on campfires in northwest B.C. as of noon Saturday.
Last month, it rescinded the ban after rainfall and a drop in temperatures dampened fire activity.
Campfires remain prohibited across the province, except in the Prince George Fire Centre covering north-central and northeast B.C.
According to Natural Resources Canada, human-driven climate change means hot and dry weather will happen more often, drying out plant matter that fuels fires, and creating the conditions in which they thrive.
Researchers also expect climate change to increase the amount of lightning in the province, which could lead to more fires starting.
