    The alpine is still variable in total amounts of snow but the basal layers haven't changed. The entire lower half is either facets, or depth hoar. Thin weak areas should be treated as suspect and avoided.

Terrain and Travel Advice

  • Be aware of the potential for surprisingly large avalanches due to deeply buried weak layers.
  • Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.

Snowpack Summary

Sun crusts continue to form on steep solar aspects. Generally a weak snowpack. The surface wind slab at tree line and above is slowly gaining strength but is still producing planar results down 20cm from the surface. Natural avalanches are possible and the consequences would be significant because any trigger would likely make the entire snowpack slide.

Weather Summary

Sunday: A mix of sun and cloud with isolated flurries throughout the day.

Day time highs of -10 and 20-30km/h SouthWest winds.

Monday

Monday: Mostly a snowy day with a forecasted 15-25cm. Freezing level will rise to 1800m (spray road elevation) Winds will be 40-50km/h out of the southwest
