jonas hoke,
Expect rugged travel in the shallow and refrozen snowpack at lower elevations. Remember to think about avalanche hazard as travel improves with elevation; we recently received over 50cm of snow up high.
Summary
Weather Forecast
Cool temps and mostly stable weather are forecast for the weekend.
Friday: A mix of sun and cloud. Alpine High -4 C, Low -8 C. Light ridge wind. Freezing level (Fzl): 1400 m.
Saturday: A mix of sun and cloud. Alpine High -8 C. Ridge wind light NE. Fzl: 1000 m.
Sunday: Sunny. Alpine Low -15 C, High -9 C. Ridge wind light NE. Fzl 500m.
Snowpack Summary
The recent wet storm saturated the snowpack below 2400m. Over 50cm of new snow fell in the upper alpine, accompanied by W winds of up to 160km/hr. A cooling trend followed, and has refrozen this saturated snow. It continued to snow as it cooled, so there may be some low density snow over the previously devastated surfaces as you gain elevation.
Avalanche Summary
Numerous loose wet avalanches up to size 3 (large) were observed in the highway corridor yesterday from all aspects. No backcountry observations have been made since the onset of the storm, but I suspect a similar cycle to have occurred.
Confidence
Problems
Storm Slabs
Extreme wind and heavy snow recently built slabs in the Alpine. It has since cooled, but these may remain reactive in the high alpine.
- The new snow will require several days to settle and stabilize.
Aspects: North, North East, East, South East, South.
Elevations: Alpine.
