Weather Forecast
Tomorrow is expected to have a chilly start. -21 in the morning! There will be a rapid warming trend just before noon with a day time high of -9. No new snow and very light winds from the SW in the morning. The afternoon winds will pick up a bit with gusts to 34km/hr from the SW.
Avalanche Summary
Nothing new today.
Snowpack Summary
Moderate to strong winds last night made short work of the new snow. Lots of exposed ridges in the alpine which means there is some crossloading happening in the alpine and upper treeline. In sheltered areas the snow was still soft, yet slightly disturbed by the wind. Overall the midpack feels well settled and solid at treeline. There is a weak layer(dec31 surface hoar) down 50-80cm, but it seems well bonded. Last week's rain crust is down 20-25cm and obvious in all places below 1950m. So far no problems are associated with this crust.
Terrain and Travel
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
Problems
Wind Slabs
Winds overnight will be variable so expect new slabs on almost all aspects. Buried slabs are on all easterly aspects and in many places there are multiple layers.
Aspects: North, North East, East, South East, North West.
Elevations: Alpine, Treeline.
Likelihood
Expected Size
Deep Persistent Slabs
Large triggers are a concern. Cornices, or other avalanches could wake this layer up.
Aspects: All aspects.
Elevations: Alpine, Treeline.
