Avalanche Problems
Loose Wet
Wet loose activity will increase with day time warming. Pay close attention to steep rocky solar slopes.
- Minimize exposure to steep, sun exposed slopes when the solar radiation is strong.
Aspects: East, South East, South, South West, West.
Elevations: All elevations.
Likelihood: Likely
Expected Size: 1 - 2

- Give cornices a wide berth when travelling on or below ridges.
- Cornices become weak with daytime heating.
Aspects: North, North East, East, South East, North West.
Elevations: Alpine, Treeline.
Likelihood: Possible
Expected Size: 1 - 3
