Points saillants

It looks like one more mainly dry day before the snow returns. Avalanche danger will rise as new snow accumulates. How quickly this happens depends on how much snow and wind we see.

Avalanche Summary

Some minor loose snow sluffing has been observed but there are no new reports of slab avalanches.

Snowpack Summary

10-15 cm of dry snow sits on a variety of old surfaces including a melt-freeze crust on solar aspects in the alpine, smooth old snow on higher elevation lee slopes, and well-developed surface hoar in sheltered areas at treeline and lower elevations. This dry surface snow is capped by a sun crust on steep solar aspects, or a fresh layer of surface hoar on sheltered and shady slopes at all elevations. Variable winds have created soft wind slabs in lee and cross-loaded terrain in alpine areas. The mid and lower snowpack is generally strong, with the exception of shallow snowpack areas.
