    There remains a concern for deep weak layers in thin snowpack areas. Warm temperatures and solar radiation have the potential to wake them up.

Snowpack Summary

Snowpack structure varies greatly with aspect, elevation and time of day. We received 2-5 mm of precipitation over the weekend with a 1600m freezing level.  New snow sits over a 4cm melt freeze crust on solar aspects above 1700m. Pockets of dry snow over windslab still exist on north aspects above TL. Midpack is strong above 1700m & Isothermic BTL.

Avalanche Summary

No new avalanche activity last 48h. A widespread, loose wet avalanche cycle during last weeks tropical heat has filled many avalanche paths with debris.
