Regions

Kananaskis, Bow Valley, Highwood Pass, North 40, Spray - KLakes.

Expect a large temperature swing tomorrow with a fair bit of solar input. This could weaken the snowpack and possibly make south aspects more avalanche prone. Keep an eye on the thermometer and watch for softening snow.

Confidence

Avalanche Summary

Nothing new today.

Snowpack Summary

Recent storm snow has settled to about 40cm at treeline with a total snow depth of 210-245cm. North aspects are tightening up well with the cooler temperatures. Mar 7th doesn't seem to exist, but the Feb 14th is still noticeable down about 110cm. South aspects have a couple of crusts worth looking at before committing to open areas. What we call the Mar 7th is down 80cm. Its a centimeter thick and prominent. Interestingly, in tests there was a layer of facets 5cm above the crust that was reliably failing in the moderate range. Worth investigating when you're out and about.

Weather Summary

Looks like there is a significant warming trend coming our way. Tomorrow will see freezing levels jump to over 1800m by day's end. The predicted high is +1 by 2pm. The warmth will stay with us for at least a few days with overnight temperatures holding above zero at 1800m. Winds will be moderate and from the SW. We will see some flurries develop later in the week, but for Monday we aren't expecting much.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Use extra caution for areas that are experiencing rapidly warming temperatures for the first time.

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.
