Snowpack Summary

On Friday January 5th the rain began to fall in earnest. By Friday evening the Strachan weather Station at 1220m had recorded 53mm of total rain fall. This rain has saturated the entire snowpack on all but the highest elevation slopes. Gradually cooling temperatures through the day on Saturday have more than likely created a crust on the surface of the snow at elevations above 1100m. Looking down into the snowpack there are a few prominent melt-freeze crusts that were buried mid-December and are now 50 to 100cm below the surface. Snowpack investigation Friday afternoon revealed rain is not pooling at these crusts with any significance.The rain has reduced the snowpack depth at 1000m to about 140cm and many early season hazards are still present at lower elevations.
