These giant clouds are the result of the Boston Bar wildfires — more than 200 km away — experts say

Photos of giant, cauliflower-like clouds are popping up on Vancouver-area social media feeds that experts say are pyrocumulus clouds produced by a wildfire more than 200 kilometres away.

The B.C. Wildfire Service said the Anderson Creek fire was discovered by aircraft responding to one of the other nearby fires on Tuesday and it quickly flared up, fanned by strong winds. 

Matt Loney, a meteorologist with Environment Canada, says each fire generates a lot of heat, and the Anderson Creek fire looks like it “really took off.”
