Avalanche Summary

No field teams out today.

Snowpack Summary

Tuesday's storm brought warm temps and rain along the spray valley with above 0° temps in the afternoon. Places like Aster lake and the highwood received about 30cm of snow and slightly cooler temperatures. This will sit on top of a melt freeze crust everywhere except the highest of North aspects. The deeper layers are still a concern where the snowpack is thin or when the crusts break down.

Weather Summary

Tuesday storm cycle hit the more southern part of the range. Spray valley got warmer temps and rain, not great. Wednesday will see a mix of sun and cloud, day time high of -9 and 25-40km/h North wind. Freezing levels to 1400m

Terrain and Travel Advice

  • Be cautious of sluffing.
  • Avoid thin areas like rock outcroppings where you're most likely to trigger avalanches failing on deep weak layers.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
