Weather Forecast

A cooling trend is happenning over the next few days and then on Saturday, there is snow in the forecast.  Models vary at this time but we may see up to 20cm of new snow.  Winds are forecast to be calm over the next few days.

Avalanche Summary

No new avalanches were observed. 

Snowpack Summary

10-15cm of snow is overlying the 0327 interface at 2200m and above.  There was also surprisingly little wind affect despite strong winds earlier in the week.  Field teams on Thursday were in the Turbine canyon area and found a generally well settled snowpack above 2200m.  In the top 30cm of the snowpack there are a series of crusts from last weeks heat.  No shears were observed on these crusts but that may change when we get a large load of new snow like we usually do in the spring.  The crust remained intact throughout the day on Thursday as temperatures remained cool.  At lower elevations, when the crust breaks down, the snowpack is purely isothermal.
