    A sunny Monday morning may produce wet loose avalanches as recent new snow (3 to 15 cm) warms. Activity will likely be limited to the new snow. The likelihood of wet loose avalanches will be higher in areas that received greater snowfall.

Confidence

Avalanche Summary

Sunshine reported several small loose wet avalanches, both natural and ski cut, involving the recent 7 cm of new snow as it became moist with daytime heating. This occurred on all aspects except high polar aspects. No other avalanches were observed or reported.

Snowpack Summary

3 to 15 cm of new snow fell with very light to calm winds, overlying sun and temperature crusts on all aspects to 2300 m, and to ridge top on solar aspects. New snow will become reactive with minimal solar input, while prolonged heating may break down underlying crusts. True north aspects hold dry, settled snow above 2300 m. The Jan 24 layer is down 70 to 160+ cm over a generally strong snowpack.

Weather Summary

Clear morning with unsettled afternoon conditions and potential for convective build up. Winds are forecast to remain light to moderate from the west southwest. Temperatures will be on the cool side of seasonal, with valley highs near 5 and ridge top temperatures around -5.

Terrain and Travel Advice

  • Cornices often break further back than expected; give them a wide berth when traveling on ridgetops.
