Avalanche Forecast

The field team saw evidence of avalanches in the last 24h up to size 3. While the amount of activity is decreasing, natural and human triggering is still very possible.

One notable avalanche at Bow Summit ran onto the standard traverse track. See MIN.

The recent storm snow continues to settle and feel the affects of the cold. Faceting of the upper snowpack was observed by the field team today as was extensive wind transport at ridge top elevations. Wind-slab's continue to develop at tree-line and into the alpine. These slabs have been formed primarily by north and east winds. These slabs are still reactive to human triggering. There are crusts in the middle of the snow pack and the base of the snowpack is still weak with basal facets. Test profiles done today are still producing sudden results in the basal facets.

Today's field team did a profile with a visiting forecasting team from Norway, which can be HERE.

The next front will begin to move into the region tomorrow, slowly starting to warm temperatures up. Forecast highs in the alpine are between -15 and -20. As the front arrives, winds will shift to a southerly flow and increase in strength. Mainly clear skies tomorrow, with clouds developing in the afternoon. Friday night will be cold again before we break out of the cold snap on the weekend.

• Make conservative terrain choices and avoid overhead hazard.
• If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.
• Cornice failure may trigger large avalanches.
