Recent weaknesses and crusts, low density new snow with strong winds, topped with increasingly dense snow after about noon today, with further warming Tuesday. Think of the new snow as being top-heavy.
A cornice fall or avalanching new snow could release much thicker buried slabs.
Now looks like the warmest temperatures were during the day Monday. However, heavy snow continues and the upper layers will settle into more of a slab atop low density snow and weak layers/crusts. Winds will enhance that slab formation.
Both Stevens Pass and Snoqualmie are closed with avalanches running onto roadways yesterday with the warming.
This whole scary and unpredictable mess may well get taken out by a potentially warm, wet storm around Sunday or Monday the 21st.
