Terrain and Travel Advice

Use caution when approaching steep and rocky terrian.
Early season avalanches at any elevation have the potential to be particularly dangerous due to obstacles that are exposed or just below the surface.
Be carefull around freshly wind loaded features.

Problems

Wind Slabs

Aspects: All aspects.

Elevations: Alpine.

Likelihood

Possible

Expected Size

1 - 1.5

Loose Dry

Cold temperatures and additional snowfall the evening will increase the likelihood of dry loose avalanches in extreme terrain. Be aware of your overhead hazard and exposure to consequence.

Aspects: All aspects.

Elevations: Alpine.

Likelihood

Possible

Expected Size

1 - 1.5

Deep Persistent Slabs

You must keep this basal layer on your radar as triggering is possible in isolated features, such as steep rocky terrain where you find yourself standing on the surface and not wallowing in facets, that's the problem slab.

Aspects: All aspects.

Elevations: Alpine.

Likelihood

Unlikely - Possible

Expected Size

1.5 - 2.5
