Large, overhanging and, fragile cornices are primed for triggering with high freezing levels and sunny skies.
Stay well back from the edge of ridges, and slopes threatened by cornices.
Cornices are large and overhanging and remain a concern while warm temperatures persist. Cornice growth may continue during forecasted extreme winds at upper elevations.
Elevated freezing levels coupled with sun may break down a surface crust formed overnight keeping the wet loose problem on the table. Keep an eye out for moist surface snow and avoid steep slopes during intense solar radiation.
Clear skies overnight has developed a surface crust over moist snow.
Above 1800 m recent snow is rapidly settling over a crust and facets. In open terrain windward features are scoured back to this crust, and is wind affected in lee features.
The mid/lower snowpack is generally well settled and strong.
Cornices are reported to be large and looming. Be mindful of them overhead or when travelling on ridge tops.
