What is a feature of foehn winds that contributes to fire risk?

Foehn winds are characterized by descending air that compresses and warms as it moves down the leeward side of a mountain range. This process leads to high wind speeds and significantly lower relative humidity (RH) in the affected areas. The combination of these factors creates an environment that is conducive to wildfire outbreaks.

High wind speeds can quickly spread flames and embers, increasing the potential for a fire to expand rapidly. Additionally, low relative humidity means that vegetation is drier, making it more susceptible to ignition. The hot, dry conditions created by foehn winds can contribute directly to the intensity and behavior of wildfires, making fire management particularly challenging in these conditions.
