Avalanche Forecast
Regions: Jasper.
You can now find a melt freeze crust on solar aspects up to tree line. A slight change in your aspect can be the difference between finding dry powder and a breakable crust. Caution as the sun comes out on solar aspects.
Weather Forecast
The temperatures continue to drop slowly to lows of -15 overnight.
A mix of sun and cloud with moderate SW-W winds.
No real snow accumulation is expected.
Snowpack Summary
Warm temps and high solar input have created crusts and moist snow on solar aspects at TL and below. Continuing SW winds have extensively redistributed the snow pack at TL and ALP. The mid pack is supportive in deep areas, but shallow snowpack areas are weak and failing on buried facet layers in test results.
Avalanche Summary
Field teams down south today noted no new avalanche activity today. Limited visibility in the alpine.
Confidence
Avalanche Problems
Wind Slabs
Ongoing moderate SW winds will continue to form slabs in the alpine and exposed tree line features. These wind slabs sit on the Feb 20th facet interface giving hard test results
- If triggered the wind slabs may step down to deeper layers resulting in large avalanches.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood: Possible
Expected Size: 1 - 2.5
Deep Persistent Slabs
Caution in thin facetted snowpack areas where triggering is more likely. This is a low probability but high consequence problem.
- Avoid shallow snowpack areas where triggering is more likely.
Aspects: All aspects.
Elevations: All elevations.
Likelihood: Unlikely - Possible
Expected Size: 2 - 3
