In sintesi

Be aware that a low rating does not rule out all avalanche potential. Keep the head up and still watch for localized instabilities.

    The cold has really helped this layer lock in place. It is still worth some thought as to what the consequences of your given terrain may be if it were to avalanche. Steep, unsupported terrain demands some respect still.

    Some recent cornice triggered avalanches show us that big triggers can easily hit the deeper layers and cause a slide. Be to sure to assess overhead terrain from a potential triggering perspective

Confidence

Good

Weather Forecast

The cooling will continue for the next while. Overnight alpine lows will hit -13. Tomorrow's high will be -14. We will see some flurries as well, but amounts will be insignificant. Winds will come around to the NE and average 30km/hr at ridge line.

Avalanche Summary

A few small, isolated loose dry out of steep terrain. There was also a large natural cornice triggered avalanche above three isle lake within the past few days. This supports the large trigger idea when it comes to the deeper layers.

Snowpack Summary

Up to 5cm's fell last night in convective flurries with very little wind. The winds did pick up in the afternoon, which blew some alpine ridges clean. There is likely a few isolated storm slabs in immediate lees, but they'll be small. Aside form that not much change. A snow survey flight today had a much weaker snowpack in the southern area of the Park. The further north we moved, the better it seemed. Snow depths at treeline were about 170cm's.
