Avalanche Summary

No new avalanches reported or observed.

If you are heading into the backcountry, please share your observations on the Mountain Information Network (MIN).

Snowpack Summary

A new melt-freeze crust is expected to form Monday night. Underneath, 15 to 30 cm of snow rests on a thick, solid melt-freeze crust dating back to March 21.

The middle of the snowpack consists of an overlay of well-consolidated snow and melt-freeze crust.

At higher altitudes, the eastern and southeastern slopes enjoy better snow cover, while the southern, western and northern slopes are rather bare.

At mid-mountain, snow depth varies between 60 and 180 cm.

Weather Summary

WEATHER FOR THE PEAKS AND SUMMITS OF THE CHIC-CHOCS

A weather cocktail from Colorado is bringing snow, rain, sleet, and freezing rain.

Monday evening and night: Mixture of snow, freezing rain and rain overnight. Possible accumulation of 2 to 4 cm of snow and 4 to 6 mm of rain/freezing rain. Wind from the southwest at 20 to 40 km/h. Temperatures rising to +4. Freezing level at 1500m.

Tuesday: Cloudy. Wind west, 40-60 km/h. Temperatures dropping to -3 in the afternoon.

Wednesday: Sunny. Wind northwest, 30 to 50 km/h. High -13.

Thursday: Snow. Accumulation of 10 cm. Wind south, 40 to 60 km/h. Maximum -8.

Terrain and Travel Advice

  • Carefully evaluate steep lines for wind slabs.
  • Closely monitor how the new snow is bonding to the crust.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
