Avalanche Summary
No new avalanches were reported on Monday. If you have any recent observations during your travels, we would greatly appreciate it if you posted a photo or any other information to the Mountain Information Network (MIN). Thanks!
Snowpack Summary
Around 30 cm of recent snowfall has been blown around by southerly wind, forming wind slabs in exposed terrain. This recent snow overlies a thick melt-freeze crust. This snow surface will likely be moist below 1600 m. The snowpack is rapidly melting below treeline.
Problems
Wind Slabs
Wind slabs in lee terrain features near ridges remain suspect. Use added caution when entering these slopes.
- Be careful with wind-loaded pockets, especially near ridge crests.
- Expect conditions to change rapidly with aspect and elevation.
- Use small slopes without consequence to test the bond of the recent snow.
Aspects: North, North East, North West.
Elevations: Alpine.

Expected Size
Loose Wet
Loose wet avalanche activity may increase late in the day if rain soaks the recent snow. Loose wet avalanches can grow in size quickly, so use added caution if it is raining on previously dry snow.
- Use added caution during periods of rain, particularly if the snow is moist or wet.
- Avoid terrain traps such as cliffs and gullies that increase the consequence of small avalanches.
Aspects: All aspects.
Elevations: Alpine.
