Good spring skiing conditions continue for those willing to walk high enough to escape the surface crusts. Short bursts of convective snow showers can add up and make for good powder skiing on north facing slopes in April.

Summary

Weather Forecast

Sun, snow, rain, wind and good overnight freezes are forecast. Not enough of any one thing to change the danger rating.

Snowpack Summary

Melt-freeze with some good powder on dark, high aspects. Otherwise, surface crusts exist on most aspects and elevations in the morning, deteriorating by noon. Deep facets can be found on high north aspects.

Avalanche Summary

No new avalanches observed or reported today. A small windslab was triggered in a cross loaded slope under the Granddaddy Couloir on Tuesday.

Confidence

Problems

Persistent Slabs

This problem remains in our forecast due to the weak structure of the snowpack, but we have not seen it produce an avalanche for several weeks. Regardless, we suggest caution in high elevation shaded areas where the snowpack is unseasonably weak.

Aspects: North, North East, East.

Elevations: Alpine.
