Early starts and early finishes are the safest way to approach Spring travel. Be aware that the frozen valley-bottom surface you skied on in the morning will be mush in the afternoon.
Summary
Weather Forecast
Mainly cloudy today with isolated flurries during the day and ~10cm of snow tonight. Freezing levels will rise to 1800m and winds will be light to moderate from the SW. Mixed sun and cloud Sunday through Tuesday with freezing levels hovering around 17-1800m until Wednesday, when we should see a dramatic warm-up with freezing levels rising to 2900m.
Snowpack Summary
High elevation N aspects still hold a winter snowpack with surface windslab that may be sensitive to human triggering given the right location. On all other aspects, expect temperature and sun crusts until daytime warming softens the surface. The snowpack is isothermal below these surface crusts at tree-line and below tree-line elevations.
Avalanche Summary
A size 3.5 natural glide crack avalanche adjacent to the highway released during Thursday morning. No other new activity has been observed.
