Weather Forecast

Avalanche Summary

Loose wet avalanches are still occurring as the day warms up and temperatures increase.  Temperature and quality of freeze overnight is whats is driving the avalanche hazard right now.  Cold and good freeze means avalanches are less likely, as temps warm up and overnight freezes become less common, avalanches will be likely. 

Snowpack Summary

The winters snow has generally melted off at lower elevations but significant snow can still be found in alpine terrain.  As long as there is snow in the mountains there is avalanche potential so always be thinking about consequences as you travel and what would happen if.  Cornices should also be carefully evaluated. 

Problems

Deep Persistent Slabs

An icon showing Deep Persistent Slabs
In general the bottom layers are still weak and suspect. Especially in the alpine and/or polar aspects. Large triggers such as a big influx of heat or a cornice collapse can wake up these basal layers.
Avoid exposure to overhead avalanche terrain, large avalanches may reach the end of run out zones.Travel early before the heat of the day, and avoid big slopes in the afternoon.

Aspects: All aspects.

Elevations: All elevations.

Likelihood

Unlikely - Possible

Expected Size

2 - 4

Loose Wet

An icon showing Loose Wet
As the snowpack warms we become increasingly susceptible to loose wet avalanches. Steep terrain and gullies should be treated with caution if the snow is moist or wet.
If triggered the loose wet sluffs may step down to deeper layers resulting in large avalanches.Use extra caution on slopes if the snow is moist or wet.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood

Possible - Likely

Expected Size

1 - 2
