Regions: Little Yoho.

Precipitation is in the forecast.  We hope for snow, but expect plenty of rain.  SH

Weather Forecast

Continued high freezing levels Friday as Easterly winds provide upslope snow and /or rain Friday evening.  A cooling trend for the weekend with current forecasts showing up to 30mm from Friday night to Sunday night possible.  Snow should fall at higher elevations, but expect plenty of rain for a large part of the forecast period. 

Snowpack Summary

The snowpack is enduring repeated freeze/thaw cycles with very high overnight freezing levels the past few nights. Avalanche danger predominantly relates to temperature, sun affect and surface crust integrity under these conditions (spring).

Avalanche Summary

No avalanches observed or reported today however afternoon loose/wet avalanches are a daily occurrence.

Confidence

Avalanche Problems

Loose Wet

Minimal crust recovery is expected Friday AM. If it is not significantly frozen when you start you trip early in the morning, make other plans.

  • Watch for clues, like sluffing off of cliffs, that the snowpack is warming up.
  • Travel early on frozen crusts before the heat of the day.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Very Likely

Expected Size: 1 - 2
