Avalanche Forecast

Issued: Apr 28th, 2022 4:00PM

The alpine rating is below threshold, the treeline rating is below threshold, and the below treeline rating is below threshold. Known problems include Loose Wet and Storm Slabs.

William Lawson,

Increased loose wet activity is possible Friday with forecasted clear skies and 2200m freezing levels.

Summary

Weather Forecast

Decent refreeze forecasted for Thursday night with a clearing trend into Friday. Slightly warmer temps Friday with freezing levels climbing to 2200m. Upper elevation winds are expected to stay in the light to moderated range from the SW.

Snowpack Summary

Recent storm snow has settled quickly. Where this new snow has not melted away it overlays crusts that exist on all aspects below 2300m and high into the alpine on solar aspects. High N aspects still hold dry powder and some wind effect on lee slopes. Crusts are breaking down and reforming almost daily depending on solar input and freezing levels.

Avalanche Summary

No new avalanches observed or reported today.

Confidence

Problems

Loose Wet

An icon showing Loose Wet

Treeline and below will likely deteriorate by the PM, and  higher on solar aspects. This includes breakdown of crusts and/or warming of the 5-15 cm of recent storm snow.

  • Daytime warming will weaken surface layers.
  • Minimize exposure to steep, sun exposed slopes when the solar radiation is strong.

Aspects: All aspects.

Elevations: All elevations.

Likelihood

Possible

Expected Size

1 - 2

Storm Slabs

An icon showing Storm Slabs

The recent storm snow has settled quickly. We have limited observations of how this new snow is bonding to the old surface. The main concern for this problem is at upper elevations predominately on Northerly aspects.

Aspects: All aspects.

Elevations: Alpine.

Likelihood

Possible

Expected Size

1 - 1.5
