GNFAC Avalanche Advisory for Thu Apr 6, 2017
Yesterday, cooler temps and cloudy skies kept the wet snow avalanche danger at bay. Today, warmer temps and periods of sun could produce wet loose avalanches on sun exposed slopes.
Dry snow at upper elevations combined with strong winds has created perfect conditions for wind transport in the high Beartooths. This makes wind slabs the main avalanche concern in this area. Photo B. Campbell

Spring is an amazing time. You can ski in the morning and golf in the afternoon. Today will be Taylor Made for both activities. Skiing or riding will be best early in the day before sun and warming temps soften the snow surface.
Skiers in the Tobacco Roots observed these small natural dry snow avalanches. These are good examples of what skiers and riders can expect to find when traveling in alpine terrain across the advisory area. Photo G. Antonioli

In a 150cm deep snowpit I found the snow to be moist. It broke in an ECTP22 on wet grains near the ground. The snow structure is changing daily with the spring weather. Stability is not simple to assess unless it's well below freezing and "locked up". Photo: GNFAC
