Terrain and Travel Advice
- Storm slab size and sensitivity to triggering will likely increase through the day.
- Watch for signs of slab formation throughout the day.
Problems
Storm Slabs
Storm slabs will build with the forecasted heavy snow. New snow may take some time to bond to the underlying crusts.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood
Expected Size
Loose Wet
The snowpack at lower elevations remains slurry and saturated. As the snowpack approaches its melting point it will result in a loss of cohesion.
Aspects: All aspects.
Elevations: Below Treeline.
