Winter continues above 3000'. 30cm HST with 45mm HNW at 2500'. Skiers triggering slabs to 60cm thick in the Upper elevation.

After the April 16-24 widespread avalanching of sun affected slopes, the snowpack at the Lower elevation is ablating rapidly.

Because of the depth hoar in the Upper elevation, large avalanches are possible over the next few weeks. At Thompson Pass 1275cm (504") of snow fell this winter, which is the average of the past 57 winters.

There is 18 hours of sunlight gaining a further five minutes each day. Snowpack stability changes rapidly from GOOD with frozen snow to POOR with melted snow. Monitor changing conditions and use extra caution.

Regional stability ratings will not be posted until next winter.
