Regions: Jasper.

The change to warmer, more dynamic weather is welcome, and has added little to hazard.  However, do keep an eye on solar warming on steep, sunny slopes; forecasts disagree how much punch the sun will pack.

Weather Forecast

Welcome relief, with relatively mild daytime highs and reasonable lows. Saturday: A mix of sun and cloud. Treeline Low -15, Hi -10. Light NW breeze.  Sunday: Similar, except mainly sunny, with a strong temperature inversion in the AM. Early next week, heavy snowfall and rising winds possible.Mountain weather forecast available at Avalanche Canada.

Snowpack Summary

2-5cm new snow Thursday night, with Moderate SW winds, has generally had little affect on the snowpack.  Isolated small windslabs could, however, exist in Maligne area.  The upper snowpack remains faceted; sluffing in steep terrain may be possible with ski traffic or strong sun. A strong midpack overlies the (dormant) basal weakness.

Avalanche Summary

No new avalanches observed during a 93N road patrol, and forecasting day in the Hilda ridge area.  No new avalanches reported.

Confidence

Timing or intensity of solar radiation is uncertain on Saturday

Avalanche Problems

Loose Dry

While skiier triggered sluffs may be possible in some areas if adventuring into very steep, shaded terrain, minimal natural activity is expected.  If any, it will be isolated to steep sunny slopes during the afternoons.
Minimize exposure to steep, sun exposed slopes when the solar radiation is strong.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible

Expected Size: 1 - 1
