A wildfire expert says powerful winds with shifting directions and dry weather contributed to rapid expansion of the fire at a military base in Wainwright, Alta., that left four soldiers dead and 39 others wounded.
Environment and Climate Change Canada had issued a severe weather alert for swaths of Alberta on Saturday, warning of powerful wind gusts of up to 90 kilometres per hour in the region where the base is located, 200 kilometres southeast of Edmonton.
The agency said a strong cold front also passed through the area at the time of the windstorm.
Jen Beverly, an associate professor of wildland fire at the University of Alberta, says that weather combination created a “perfect storm” for the deadly fire to spread at a staggering speed and engulf the military training ground.
Defence officials have said that 84 members of the Princess Patricia’s Canadian Light Infantry were in a training area when strong winds spread the flames from a nearby grass fire that was initially considered sufficiently under control.
The military said the fire burning about a kilometre away reached the training ground in less than one minute, and Beverly says that could be “the fastest recorded observation of wildfire spread in Canada” if confirmed after the investigation.
Beverly says people working near a wildland fire should have access to information about any severe weather conditions, including extreme winds.
She says the military’s investigation needs to find out whether such information was communicated and if any decisions made about the training were based on it on the day of the fire.
