The Alberta Wildfire, 2016
- 'The Beast'
- Canada, in a forest to the southwest of Fort McMurray
- CAUSE
- Unknown
- Initially under control, but a shift in wind direction intensified fire
- 'Spotting' - wind carried burning embers to ignite fires ahead of fire front - harder to mitigate.
- Jumped a one kilmetre river in places
- Favourable environmental conditions
- Lack of winter snowfall and an early snow melt
- Warmer than average temperatures dried out ground
- Temperatures soared late April, low humidity, tinder dry
vegetation
- Due to El Nino
- Earlier springs in high latitudes
could extend fire season
- What made it worse once the fire started?
- Temperatures exceeded 30 degrees Celsius, winds increased to supply oxygen
- Fire created weather patterns - lightning led to more ignition
- Positive Feedback
