Minimize exposure to steep solar slopes when the sun's impact is making the snow moist or wet.

Avalanche Summary

No new avalanches were reported in the region on Monday. Backcountry users will likely see evidence of a small wet loose avalanche cycle from recent rain and solar input below treeline.

If you head out in the backcountry, let us know what you are seeing by submitting a report to the Mountain Information Network.

Snowpack Summary

In the upper most alpine you may find 5-10 cm of dry wind-affected snow. A melt-freeze crust covers all aspects to 1600m. Below 1000 m surfaces may remain moist. The middle and lower snowpack are consolidated and strong, containing numerous thick and hard melt-freeze crusts.

Weather Summary

Tuesday Night

Few clouds clear through the night. Light southeast winds at ridge top. Treeline temperature low 0°C. Freezing levels 1600 m.

Wednesday

Mainly sunny in the morning with increasing clouds in the afternoon and isolated flurries, 1-2 mm. Light southwest winds at ridge top. Treeline temperature +2°C. Freezing levels 1600 m.

Thursday

Cloudy with scattered flurries, 5-10 cm accumulation. Strong south winds at ridge top. Treeline temperature -1°C. Freezing levels drop to 1000 m.

Friday

Mix of sun and cloud with isolated flurries, 2-5 cm accumulation. Light northwest winds at ridge top. Treeline temperature -1°C. Freezing levels drop to 1000 m.

Terrain and Travel Advice

  • The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
  • Rocks will heat up with daytime warming and may become trigger points for loose wet avalanches
  • A crust on the surface will help bind the snow together, but may make for tough travel conditions.

Avalanche Problems

Loose Wet

The upper snowpack continues to adjust to the recent spring-like weather. Expect small loose wet avalanches to be reactive on steep, solar aspects with sun and warm temperatures.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible

Expected Size: 1 - 1.5
