Good morning, this is
Out of the direct sun on Thursday temperatures remained fairly cool. Winds were slightly gusty transporting some snow along the upper ridges. Temperatures dropped into the mid teens overnight and wind speeds bumped just slightly from the north northwest.
Snow and Avalanche Discussion:
Observations from Thursday included scattered small wind slabs that would crack with the weight of a person, sluffing on sustained steep north facing slopes, minor wet activity on southerly facing slopes and a couple of cornice falls, one coming off naturally. Diurnal near surface faceting is metamorphosing the snow on the northerly aspects. This weakening of the snow surface is the partial cause of the sluffing and also responsible for a couple of wind slabs that failed on top of it.
Expect to see scattered small pockets of wind drifted snow that may crack again today. Sluffing should be monitored again on sustained steep northerly slopes and minor wet activity should also be kept in mind. The consequences of these problems are not that great unless you’re in exposed terrain where if you get knocked down you’ll get pushed into trees or over rocks. Also, cornices need more attention during the spring as warmer temperatures stress them enhancing their sensitivity.
Bottom Line for the
The avalanche danger is generally LOW. There are isolated pockets with a MODERATE danger on steep, upper elevation, wind exposed slopes, which have recent deposits of wind drifted snow. Watch for sluffing on steep northerly aspects as well. As usual with any clear day at this time of the season, expect the southerly slopes to become wet which may produce some minor activity. Give cornices their due respect.
We’ll see some high clouds today with slightly warmer temperatures and light to moderate northwest winds. Temperatures will get into the mid to upper 30s at 8000 feet and around 30 along the higher ridges. A mild storm system will move through Saturday bringing 2 to 6 inches of snow. We’ll see partly cloudy skies Sunday with a slight chance for flurries then clearing for Monday. Another system with a decent cold front is shaping up for late Tuesday but not looking like a blockbuster by any means.
