Summary
Weather Forecast
A fast moving cold front hauls freezing levels down from treeline to lake level on Sunday night, bringing 10-15cm of new snowfall with strong-extreme SW winds. Winds ease tomorrow, and remain moderate from the SW through Wednesday. Cool temperatures; except becoming mild late Tuesday, with a skiff of fresh snow arriving tuesday night.
Snowpack Summary
More spring-like every week: firm, with a variety of crusts making for poor skiing below treeline, and on solar aspects. Strong SW winds are forming wind slabs, found lee of ridges at treeline, and on open slopes. These should bond quickly to the old snow. A crust-facet combo buried 30-60cm is now strengthening, but worth keeping in mind.
