Spring is a dynamic time of year, conditions can vary widely and change rapidly.

Verify conditions in your local area and tune in to changes with elevation, aspect and time of day.

Summary

Confidence

Moderate

Avalanche Summary

No new avalanches were reported in this region over the past few days. However, field observations are currently very limited.

If you go into the backcountry, please consider submitting your observations to the Mountain Information Network. 🙏

Snowpack Summary

15 to 40 cm of recent snowfall exists above a crust on all slopes except true north-facing terrain at upper elevations.

Below treeline is either snow-free or has very thin snow coverage. Expect difficult travel at lower elevations.

Terrain and Travel Advice

  • Remember that in the spring strong solar radiation and warm temperatures can weaken the snow in a matter of minutes.
  • Watch for changing conditions today, storm slabs may become increasingly reactive.
  • Avoid freshly wind loaded terrain features.

Problems

Storm Slabs

An icon showing Storm Slabs

If the sun comes out, storm slab reactivity may increase rapidly, particularly on steep, sun-exposed slopes.

Expect deeper, more reactive slabs in north-facing lee terrain features.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood

Possible - Likely

Expected Size

1 - 2

Loose Wet

An icon showing Loose Wet

Even brief periods of strong solar radiation could initiate wet loose avalanches on steep, sun-exposed slopes.

Aspects: South East, South, South West, West.

Elevations: All elevations.

Likelihood

Possible - Likely

Expected Size

1 - 2
