    Watch for moist surface snow at low elevations as freezing levels stay elevated.

    Avoid sun affected slopes if skies clear and remember that cornices may also weaken with daytime warming.

Avalanche Summary

No avalanches have been reported in the last few days.

We expect warm temperatures and sunny skies may have produced loose wet avalanches, particularly on steep, sun-exposed slopes.

Snowpack Summary

Recent storm snow is settling and bonding to the snowpack. Deeper deposits may be found in north facing terrain features near ridges due to strong southwest winds. With a freezing levels remaining high, expect the surface snow at low elevations to be moist, which may freeze into a hard melt-freeze crust overnight. Solar aspects may hold a melt freeze crust into the alpine from sun affect. A dry snow surface may remain on shaded aspects at higher elevations.

The middle and lower snowpack are consolidated and strong, containing numerous thick and hard melt-freeze crusts.

Terrain and Travel Advice

  • Be alert to conditions that change with elevation and sun exposure.
  • Minimize exposure to sun-exposed slopes when the solar radiation is strong.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
