Regions: Northwest Inland.

This bulletin is based on limited data. Local variations in conditions are likely to exist. Check out the forecasters blog for further details on interpreting early season bulletins.

Confidence

Poor - Due to limited field observations for the entire period

Weather Forecast

Saturday night to Sunday: Light to moderate snowfall (up to 15cm in some locations) / Moderate to strong westerly winds  / Freezing level at 800mMonday: Mix of sun and cloud / Light to moderate northwest winds / Freezing level at 600mTuesday: Mostly clear / Light southwest winds / Freezing level at 800m

Avalanche Summary

There have been no new avalanches reported from the region. This may speak more to the lack of observations than actual occurrences. If you have any observations to share, please send us an email.

Snowpack Summary

Snow depths vary from 60cm in the Northern part of the region to about 115 cm in the Southern part of the region. Weather stations around the region recorded light accumulations on Friday with up to 40 cm falling earlier in the week. With weather forecast for Saturday night I expect new windslabs to form in exposed areas, particularly at higher elevations. These windslabs may take some time to bond and triggering may occur naturally, or by additional light loads such as a person. The data used to produce our avalanche bulletins is extremely limited at this time of the year. Any information you have about the snowpack would be greatly appreciated. Please communicate with us by email.

Avalanche Problems

Wind Slabs

Human triggered windslab avalanches are possible on open exposed slopes below ridge crests, behind terrain features, and in cross-loaded gullies.
Stay off recent wind loaded areas until the slope has had a chance to stabilize.>If you are increasing your exposure to avalanche terrain, do it gradually as you gather information.>

Aspects: North, North East, East, South East, South.

Elevations: Alpine, Treeline.

Likelihood: Likely - Very Likely

Expected Size: 1 - 4
