Variable surfaces including temp/rain crust, hard wind press and loose snow sit above the November rain crust which goes as high as 2200m. Total snow pack height in alpine is around 45-85 cm. Wind pressed/scoured features to wind slabs in lee features in the high alpine. Cross loaded gulleys may threaten ice climbs from above.
Previous strong winds transported old snow through the high alpine peaks and ridge tops. Hazard can be expected to increase in isolated areas where wind effect and loading is visible. No natural activity observed or reported in the forecast region.
