We are experiencing all freeze, no melt weather pattern. Ridgetop windslabs are on a variety of firm surfaces but appear to be bonding. Investigate for unstable conditions on isolated terrain features. Avalanches could still occur in extreme terrain.

Summary

Weather Forecast

Select a specific area at Spot Wx for localized weather forecast conditions. Parkers ridge Saturday night will be -17C and clear skies.  Monday will be sun, cloud, no new snow, -12C, and light NE winds. Tuesday will be similar, lows of -19C, highs of -15C, and light East winds. Wednesday will be a repeat of Tuesday.

Snowpack Summary

5-15cm or new snow since Thursday was redistributed by NW-SW building soft wind slabs up 30cm deep mainly in the Alpine. This precipitation was rain at lower elevations. Windslabs on solar aspects rest on a sun crust into the alpine & a melt freeze crust up to 2300m. The mid pack is dense and supportive. Cornices are large.

Avalanche Summary

No patrol occurred on Saturday and nothing new reported. On Friday, a few dry loose avalanches up to size 1.5 occurred in steep rocky terrain from 2300-3000m. Explosives work on Friday produced only a few size 1.5 loose dry avalanches on Parkers ridge.

Problems

Wind Slabs

An icon showing Wind Slabs

A bit of recent snow arrived since Thursday being redistributed by winds. The current cooling trend will promote bonding yet be cautious of wind slabs over a variety of firm smooth surfaces such asĀ  sun/temperature crusts being potentially reactive.

  • Be careful with wind loaded pockets, especially near ridge crests and roll-overs.

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