Kernpunkte

We are headed into an 'all melt- no freeze' state over the next few days.

Be sure your exit plan manages your exposure to solar slopes. Afternoon avalanche danger ratings could reach CONSIDERABLE tomorrow.

    Warming temperatures and strong solar radiation will weaken these sleepy giants. Give them respect!

    Watch for moist/wet avalanches during peak daytime warming. Steeper sunny slopes and areas with a thin snowpack are the most affected by solar radiation.

    With a few nights of limited surface crust recovery at treeline, this layer may wake up as freezing levels continue to climb. If triggered, this deep layer (down 1.5-2m in the snowpack!) will result in very large, very destructive avalanches.

Weather Forecast

Limited overnight crust recovery with alpine temperature inversions.

Tonight:  Mainly cloudy. Alpine low 1*C, freezing level (fzl) 1800m. Light south wind.

Mon: Mix sun and cloud. High 4*C, fzl 2500m. Wind light SE.

Tues: Mainly sunny. Low 1*C, High 4*C, fzl 2700m

Wed: Mix sun and cloud with isolated wet flurries. Low 0*C, High 3*C, fzl 2800m.

Snowpack Summary

We have 2 distinct snowpacks.

Below treeline the spring-time melt-freeze snowpack is solid in the morning, and breaks down with daytime warming.

In the Alpine, on N'ly slopes you'll find a more winterlike snowpack with settled dry powder, and variable crusty surfaces on solar aspects.

Cornices are large and looming.

Avalanche Summary

Numerous large (size 2-2.5) loose wet avalanches occurred today from all aspects in steep paths along the highway corridor. There was also a notable very large  (size 3) cornice release in the Grizzly highway path.  Most of these avalanches are entraining surface snow only, but a couple steep S'ly paths are starting to see some gouging deeper.
