Regions: Glacier.

Incoming snow should improve ski quality in the short term. Expect wind slab development late today and into Sunday.

Weather Forecast

Snow changing to rain showers near noon with snowfall amounts near 5cm. Freezing levels are expected to rise to 1400m to 1800m this afternoon depending which forecast you trust. Alpine temps should be in the -3C range with gusty SW winds up to 50km/h.  Gusty SW-W winds with continued light snow are forecast through to the end of the day tomorrow.

Snowpack Summary

Last week's storm snow has formed pockets of windslab lee slope alpine and treeline locations. Expect a melt freeze crust on true solar aspects at treeline and alpine locations. Protected high north aspects are the best bet for late season powder. Below treeline a melt freeze crust covers isothermal snow on all aspects.

Avalanche Summary

No new avalanches observed or reported yesterday.

Confidence

Avalanche Problems

Persistent Slabs

Moderate S -W winds have redistributed last week's storm snow into pockets of windslab on alpine and treeline lee features. These slabs overlie  a melt freeze crust on solar aspects and given the right location, surface hoar on northerly aspects.
Use caution in lee areas. Recent wind loading have created wind slabs.Be careful with wind loaded pockets, especially near ridge crests and roll-overs.

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

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2

Loose Wet

Afternoon rain showers may warm surface crusts on lower elevation S aspects to the point of surface crust break down. Small wet surface slides may occur if this comes to pass.
Use extra caution on slopes if the snow is moist or wet.

Aspects: South East, South, South West.

Elevations: Below Treeline.

Likelihood: Unlikely

Expected Size: 1 - 1.5
