Another warm day with minimal overnight refreeze will maintain wet-snow instabilities as the morning warms. Monday should be windier in the alpine, but it probably won’t be enough to limit wet snow instabilities on any slope that catches significant sun due to such warm temperatures. The past days have provided good feedback that triggering wet loose avalanches is possible on steep slopes where the snowpack feels unsupportable and sticky. It's been hot enough that you may find these wet snow instabilities on more shaded aspects or higher up the mountain than you normally see.
Look for rollerballs and pinwheels as classic warning signs to larger wet loose avalanches. The upper snowpack has not fully transitioned from dry to wet yet, so let sticky surfaces serve as another indicator that wet loose avalanches can be triggered. Triggering a wet slab is unlikely and very difficult to assess, but not necessarily impossible in terrain that was previously wind-loaded, especially as the snowpack transitions from winter-like to a more predictable spring melt-freeze structure.
The hot weather has also weakened cornices and widened glide cracks in some areas. Limit your exposure where you find these bigger overhanging chunks of snow, as they often fail without warning.

Features like this may be excellent places to trigger wet avalanches on Monday.
