Weather Forecast

Warm temperatures, sunny skies and light winds are expected to continue for the forecast period. Clear overnight skies should allow for a good freeze by morning. Strong solar radiation and daytime temperatures above freezing in the alpine are forecast.

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.
