    New cornice growth may be easy to trigger due to rising temperatures and solar radiation. Cornice falls may trigger slabs on the slopes below.

Weather Forecast

Clear skies, light winds, and warm sunny days are forecast for the next few days. There should be a good re-freeze of the surface from the alpine to the valley bottoms. Freezing levels during the day are expected to rise to about 1200 metres. Temperatures on southerly aspects in the alpine are expected to rise above freezing due to solar heating.

Avalanche Summary

Some sloughing from steep shaded aspects in the alpine to size 1.0. Also, moist surface snow releases up to size 1.0 on solar aspects.

Snowpack Summary

Crusts are developing due to melt/freeze conditions. Danger is elevated in the afternoon due to daytime warming, and lowered in the morning if there is a significant re-freeze overnight. There is a Four finger soft slab on north aspects that is 10-20 cm thick and is settling and bonding due to warm temperatures. The Feb 01 (120201) rain crust is down 10-40 cm up to about 2000 metres. The mid January crust is down between 50-100 cm, and the mid december crust is buried down up to 200 cm.
