Avalanche Summary

No recent avalanche observations have been reported.

Snowpack Summary

In the alpine, up to 10 cm cold wind-affected snow is holding onto northerly aspects. Southerly winds have produced isolated wind slabs around ridges and in the immediate lee of slopes in the alpine. Cornices have been failing recently.

A crust is found on solar alpine slopes and all aspects below. Warm overnight temperatures are preventing strong crust recovery as you lose elevation. Expect thin surface crusts to break down quickly with daytime warming and rain. Below treeline the snowpack is saturated and rapidly melting.

Problems

Loose Wet

Likelihood

Possible

Expected Size

1 - 1.5

The likelihood of loose wet avalanches will depend on the extent of overnight crust recovery and the pace at which the warms and rains through the day.

  • Cornices are reported to be touchy. Give a wide berth when travelling on or below ridges.
  • Avoid terrain traps such as cliffs and gullies that increase the consequence of small avalanches.

Aspects:

East, South East, South, South West, West.
