Avalanche Forecast
Regions: Little Yoho.
Great spring conditions. Expect high freezing level and hot afternoon temperatures by midweek. Start (very) early, finish early.
Weather Forecast
Calm and clear weather is expected to dominate the region for the next 4 days or so. Expect the freezing levels to rise considerably by midweek.
Snowpack Summary
Supportive crust on solar aspects for most of the day with 5cm of storm snow at higher elevations. Previous wind effect in alpine areas. Mid pack is well settled with no significant shears. Thin snowpack areas may have some weak basal facets but in general there are few concerns in the snowpack.
Avalanche Summary
No avalanches observed or reported.

Avalanche 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: Possible
Expected Size: 1 - 2
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.
Likelihood: Possible
Expected Size: 1 - 3
