Avalanche Summary
No new avalanche activity was reported on Monday or Tuesday. Most of the recent reported activity has been limited to loose wet slides and cornice collapses from warming and solar radiation.
Snowpack Summary
Up to 5 cm of new snow sits on a solid and thick melt-freeze crust above 1500 m. High high north aspects may have 15-30 cm of dry snow sitting on a previous crust, and possibly more where wind loaded. Warm temperatures and periods of sun will likely create moist or wet surface snow and may soften the underlying crust. The mid and upper snowpack consists of a mix of moist snow and well bonded crusts. The deep facet/crust persistent weakness buried at the beginning of February (now down up to 80-100+ cm) should stay on your radar, especially on all alpine slopes that will see the intense sun tomorrow. Any activity at this interface would be large and destructive. Also, give large sagging cornices a wide berth when traveling on or below corniced ridges.
