Kananaskis.

Cooler temperatures have formed solid supportive crusts and some new snow at treeline has freshened up the surfaces out there. Tonight the winds will be moving the new snow around into small wind slabs. Thursday temps will sky rocket again.

Summary

Confidence

Moderate - Freezing levels are uncertain

Weather Forecast

Mainly cloudy with isolated flurries. High of 0 C. Winds will be moderate to strong from the west. Freeze levels at 2300 meters

Avalanche Summary

Little to no avalanche activity in the last 24 hours to report.

Snowpack Summary

Last night we saw improved recovery (ie better freeze) that has improved snowpack stability by the development of a strong surface crust and has thus reduced the hazard. Telemetry has indicated that we received 17 cm of snow at treeline elevations and so up to 20 cm may have accumulated in the alpine with light winds overnight. The remainder of the snowpack will be largely settled grains with a mix of older buried crusts and conglomerated larger facets in shallow snowpack areas.

Problems

Be aware of the potential for large, deep avalanches.>Avoid sun exposed slopes when the solar radiation is strong, especially if snow is moist or wet.>
