Avalanche Forecast

Moderate - Uncertainty is due to how quickly the snowpack will recover and gain strength.

Aside from a few bouts of potentially strong wind, we’re moving into a rather benign weather pattern for the foreseeable future.

SUNDAY NIGHT: Freezing level at valley bottom, light to moderate northwest wind, no significant precipitation expected.

MONDAY: A few clouds, freezing level rising to 800 m in the afternoon, light wind generally out of the northwest, no significant precipitation expected.

TUESDAY: Scattered cloud cover, freezing level rising to around 1300 m in the afternoon, moderate to strong northwest wind, trace of precipitation possible.

WEDNESDAY: Scattered cloud cover, freezing level near valley bottom, light variable wind, trace of precipitation possible.

On Saturday storm slab avalanches to size 2 were widespread. They ran naturally and were intentionally triggered by avalanche control work on all aspects.  

Fragile cornices and one large cornice fall have been reported over the past week.

The weekend storm produced 15 to 25 cm of warm storm snow. This snow has been formed into slabs in wind exposed terrain by previously strong winds that were largely out of the northeast. This snow rests on previously wind affected snow and a thick rain crust that exists up to roughly 2100 m. In many areas this capping crust extends to mountaintops. Sheltered areas now have 15-30 cm of snow above the crust. The bottom 20 cm of the snowpack consists of basal facets and decomposing crusts that have not been an active avalanche problem since December, but could reemerge as a problem after sustained warming.

• Be especially cautious as you transition into wind affected terrain.
• Don't be too cavalier with decision making, storm slabs may remain sensitive to human triggering.
• Start with conservative lines and watch for clues of instability.
