Changing weather can alter stability.
Both prior to your tour and throughout the day observe the weather.
A rapid increase in heat, precipitation, and especially wind can significantly alter snow stability.
slopes tend to stabilize more quickly than shaded slopes. Warming helps
the snowpack settle and densify more rapidly. This process is slowed on
a shaded slope. However, if the snowpack is subject to a rapid warming,
the snow becomes saturated with water and instability can increase.
Snow conditions will often dictate what aspect you choose to descend,
but don't let the desire to find the best snow bias your stability
