Points saillants

A cold front is moving into the region giving us 10-15cm of snow at upper elevations and cooling temperatures under a cloudy sky. Watch for windslabs building in Alpine areas from the strong northern winds over the next few days.

    Snow/Rain may fall at lower elevations on Wednesday and into Thursday so watch for this rain to initiate wet avalanches at lower elevations.

Avalanche Summary

Numerous loose wet avalanches up to sz 2 were observed throughout the region on Tuesday.

Snowpack Summary

The snowpack has been rapidly settling over the past few days under the influence of the warmer temperatures and high freezing levels. That will all change here again on Wednesday as temperatures cool and snow moves back into the region with strong northerly winds.

Watch for new windslabs building overlying a temperature crust. In lower elevations the precipitation may fall as rain. Monitor the freezing levels as well as quality of freeze overnight before heading out.

Weather Summary

Cooler temps arrive on Wednesday as a cold front pushes into the region. Beginning mid day rain/snow will begin with close to 10cm of new snow falling at higher elevations. Winds will be out of the north into the strong range. The freezing levels for the next few days will be 1200-1400m.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Triggering deep layers is more likely if the snow surface didn't freeze overnight.
  • Keep in mind that the high density of wet avalanches can make them destructive.
  • Avalanche danger will rapidly increase if snow switches to rain.
  • A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.
