Snowpack Summary
The deep persistent weakness still exists and has been sporadically active on hot days in high alpine terrain. This will be the big thing to consider when deciding whether to get on the bigger snow and ice routes.
Avalanche Summary
In general, avalanche hazard will be greatest during hot sunny days or warm rain. This has the potential to trigger smaller loose wet avalanches and larger wet slab avalanches on the basal weak layer. For current avalanche activity and observations, check out the Mountain Conditions Report
Confidence
Problems
Loose Wet
For the most part, the snowpack has settled into a summer-like state, but loose wet avalanches are still possible on hot days in steep alpine terrain.
- Watch for clues, like sluffing off of cliffs, that the snowpack is warming up.
- Avoid sun exposed slopes when the solar radiation is strong, especially if snow is moist or wet.
Aspects: All aspects.
Elevations: Alpine.

Expected Size
Deep Persistent Slabs
The deep persistent layer has still been sporadically reactive on hot days in high alpine terrain. Think twice about committing to the big faces unless you have a very good freeze.
- Travel early before the heat of the day melts surface crusts, and avoid big slopes in the afternoon.
Aspects: North, North East, East, South East.
Elevations: Alpine.
