Terrain and Travel Advice
- Back off slopes as the surface becomes moist or wet with rising temperatures.
- Rocks will heat up with daytime warming and may become trigger points for loose wet avalanches.
- Carefully evaluate steep lines for wind slabs.
Problems
Wind Slabs
Recent storm snow may remain reactive to rider-triggering in wind-loaded areas, particularly where it overlies a slick crust.
Aspects: North, North East, East, South East, West, North West.
Elevations: Alpine, Treeline.
Likelihood
Expected Size
Loose Wet
New snow weakens as it sees warm temperatures for the first time. Watch steep, solar slopes and areas around rocks where these small avalanches could be easier to trigger.
Aspects: All aspects.
Elevations: Treeline, Below Treeline.
