A winter interlude in the middle of spring has us thinking about winter problems again. Watch for windslabs in alpine and treeline lees.
Be prepared to travel in spring conditions again later this week.
New snow and strong SW winds are forming wind slabs in immediately and ridge crests. Slabs sit top refrozen surfaces and may well not bond
As temps warm throughout the week we expect to see new snow transition to a wet loose.
Tonight: Flurries amounting 10-15 cm. Strong SW winds.
Tuesday: Cloudy with flurries. Alpine high -5 with moderate to strong SW winds. Freezing level 1600m.
Wednesday: Clearing. Alpine high 0 with light to moderate SW winds. FL 1600m.
Thursday: Mainly sunny. Alpine high of +3. Moderate SW winds. FL 3000m.
Up to 15 cm of new snow with strong SW winds has forming 15-30 cm windslabs on refrozen surfaces. Refrozen surfaces exists on all aspects well into into ALP. A series of crusts and windslab make up the midpack. Lower snowpack is well settled 1F to P. HS 250-300 cm near the continental divide.
No new avalanches observed with slightly cooler temps this week. Please report any observations to the Mountain Information Network.
