Backcountry Avalanche Conditions:
Several large Wet Slab avalanches were reported from different parts of Colorado in the last three days. These were natural avalanches and they occurred on both east and west aspects. All released at around 12,000 feet in elevation. As temperatures remain warm over the next few days, and overnight temperatures stay above freezing, we can expect to see more of these avalanches.
With the warm weather that we are dealing with, there will be very small windows to get out and enjoy steep slopes in the backcountry. In fact, it might not matter how early you wake-up, if the snow surface doesn't freeze, conditions may be dangerous first thing in the morning. Careful trip planning is necessary so that safe return options to the trailhead are available if conditions deteriorate. The highest alpine peaks may still hold colder snow and generally-safe conditions but egress may be difficult and potentially dangerous. You may have to descend through locations with the most suspect slopes which are located at near-treeline and slightly above-treeline elevations. Slopes that have a thin snowpack and are very rocky are more at risk for wet avalanches that release as slabs.
Monitor overnight temperatures using our weather station page (link below). If you see overnight temperatures above freezing, it may best to find a different spring activity for the day. Warm nights coupled with cloud cover further increase the chance that the snow surface did not freeze. When the snow surface doesn't freeze, the snowpack becomes unsupportable, collapsible and possibly dangerous. While out in the backcountry, be wary of any slope that cannot support the weight of you or your machine. Collapsing sounds and sinking into the snowpack are bad signs and an indication that you should use low-angle slopes to return to the trailhead.

We will issue a Statewide Avalanche Summary on Sundays, Wednesdays and Fridays through Memorial Day. As conditions change we will update this product any time it is warranted.
