Weather Forecast

SATURDAY NIGHT: Cloudy with flurries; 3-5 cm. / Moderate, westerly winds / Alpine low -2 C / Freezing level 1000 m.SUNDAY: Mostly cloudy / Light, westerly winds / Alpine high -2 C / Freezing level 1000 m.MONDAY: Mix of sun and cloud / Light, southwesterly winds / Alpine high 1 C / Freezing level 1300 m.TUESDAY: Cloudy with flurries; 3-5 cm / Light, southwesterly winds / Alpine high 2 C / Freezing level 1500 m.

Avalanche Summary

No new avalanches have been reported in the region on Friday. However, avalanche activity is expected to increase on Sunday with the new snow and wind.

Snowpack Summary

15-20 mm. of precipitation on Saturday fell as moist snow at treeline and rain below which sits on a melt freeze crust. Warm temperatures and wet precipitation are producing a moist, spring snowpack. The snowpack depth decreases rapidly below 1200 m.

Avalanche Problems

Storm Slabs

15-25 cm of snow on Saturday created fresh storm slabs at treeline and above.

Use small slopes without consequence to test the bond of the new snow.Pay attention to changing conditions with elevation/aspect.Minimize overhead exposure during periods of heavy loading from new snow and wind.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 1 - 2

Loose Wet

Wet flurries, rain and rising temperatures can all warm the snowpack and increase the likelihood for loose wet avalanches, especially in areas with fresh snow.

Use extra caution on slopes if the snow is moist or wet.Minimize exposure to steep, sun-exposed slopes when the solar radiation is strong.

Aspects: East, South East, South, South West, West.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 1.5
