Slope reversal can be considered extreme fire behavior?

Slope reversal can be considered extreme fire behavior?

• A. Sometimes
• B. Not sure
• C. False
• D. True

Answer: (D)

Extreme fire behavior includes abrupt, unpredictable changes in a fire’s spread and direction. Slope reversal fits this because on steep terrain a fire normally moves uphill, but shifts in wind or terrain effects can cause the fire front to reverse direction and spread rapidly in an unexpected way. That combination of sudden direction change and rapid growth makes slope reversal an example of extreme fire behavior. The other options don’t capture that potential for dramatic, dangerous change.
