Above freezing overnight temperatures at 1900m will have prevented the crust to fully recover. If the sun shines, any direct solar radiation today will increase the avalanche hazard on solar aspects.
Summary
Weather Forecast
A weakening high pressure ridge over the southern half of the interior will keep things mostly dry with increasing cloud for today. Freezing levels will reach between ~1700-2000m. Light flurries and/or rain can be expected later today. Alpine winds are not expected to relent much, they will be 50-60km/h from the west today.
Snowpack Summary
Firm crust below treeline at the surface softening with mild temperatures. Variable conditions higher up from wind deposited powder, to stiff wind slab, to bare crust. Reactive wind slab may exist at ridge crests. Recently buried surface hoar with variable distribution is down ~15cm. This sits just above the Feb 14 crust which is ~5-10cm thick.
Avalanche Summary
No new natural avalanches have been observed yesterday.
Confidence
Timing or intensity of solar radiation is uncertain
Problems
Wind Slabs
Strong winds have formed touchy slabs. Small pockets have been reactive to skiers at or near ridge crests. Winds have come from all directions over the last week so lee slopes include all aspects.
Be cautious as you transition into wind affected terrain.Use caution in lee areas in the alpine. Recent wind loading have created wind slabs.
Aspects: All aspects.
Elevations: Alpine.
