Initial reports of avalanche activity in the Fernie area on Tuesday showed numerous storm slabs releasing naturally as well as with remote triggers from skier traffic, and with explosives. Avalanches generally ranged from size 1 (small) to size 2.5 (large). The bulk of this activity was observed on north to east aspects.

Looking forward, snowfall continuing over Tuesday night is expected to maintain similarly active avalanche conditions for Wednesday.

Continuing snowfall is expected to bring new snow accumulations to 30-50 cm by Wednesday morning. The new snow has buried recent widespread wind affected snow that extended well below tree line. Recent Cornice growth in the alpine has been notable.

Several crusts layers have formed in the mid to upper snowpack as a result of recent warming and rain events. As these crusts become buried deeper, they have the potential to turn into a persistent slab problem. We'll be keeping an eye on them going forward.

The lower snowpack consists of weak faceted snow and decomposing crusts but has not been an active avalanche problem recently.

• Continue to make conservative terrain choices while the storm snow settles and stabilizes.
• Use conservative route selection. Choose simple, low-angle, well-supported terrain with no overhead hazard.
