Avalanche Problems

Loose Wet

This problem is unreactive in the morning and increases sensitivity with afternoon warmth and sun. It is critical to evaluate the degree of overnight freeze and relate it to how quickly this problem can activate during the day.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Likely

Expected Size: 1 - 1.5
