Weather Forecast

Seasonal temperatures with light flurries and no significant  wind through the weekend.

Snowpack Summary

20cm of low density storm snow sits on top of a 10cm thick laminated crust at tree line, below the crust is 20-30cm of large grain snow to ground. Pockets of wind slab may exist in the alpine and resting on the crust up to 2600m. Below treeline is un-skiable due to lack of snow. Early season conditions exist at all elevations.

Avalanche Summary

Some loose dry activity noted on steep slopes.  This could be an issue for ice climbers in the high alpine.  (Most lower elevation ice climbs are not in shape).

Confidence

Due to the number of field observations on Friday
