Cloud cover and slightly cooler temps will subdue the solar triggered avalanches. However, starting and finishing early is still smarter choice this time of year.
Summary
Weather Forecast
Increasing cloud and light precipitation are expected to start on Wednesday. Wind will remain relatively light.
Snowpack Summary
Supportive crust on solar aspects in morning which are deteriorating by early afternoon. High elevation east and north still have dry snow. Mid and lower pack is well settled with no significant shears.
Avalanche Summary
No reported or observed avalanches, however it is likely that loose and wet avalanches were running to size 1.5.
Confidence
Problems
Loose Wet
Expect solar triggered avalanche activity on steep solar aspects in the afternoon. Start early and be off steep solar aspects by midday.
- Avoid sun exposed slopes when the solar radiation is strong, especially if snow is moist or wet.
Aspects: North, North East, East, South East, South.
Elevations: All elevations.
Likelihood
Expected Size
Cornices
Cornice failures have been big enough to trigger the deep basal facets. This scenario will be exacerbated by high freezing level and intense solar radiation on Tuesday and Wednesday.
- Extra caution needed around cornices with current conditions.
- Cornices become weak with daytime heating, so travel early on exposed slopes.
Aspects: North, North East, East, South East.
Elevations: Alpine.
