Highlights

The avalanche danger is LOW, and human-triggered avalanches are unlikely.

  • Look for and avoid isolated small wind slabs formed during yesterday's elevated westerly winds. You'll likely find these on upper-elevation, steep slopes and terrain features facing the east half of the compass.
  • The best riding conditions will be on lower angle, shaded, and sheltered slopes that harbor surface hoar or weak snow on the snow surface.

    Winds blowing from the west intensified yesterday, gusting up to 45 MPH, and formed small slabs of wind-drifted snow, primarily in upper-elevation, exposed terrain. With weak, faceted snow at the base, any additional weight could cause a collapse, or avalanche, if you are on a steep slope.

    • Listen for a hollow, drum-like sound underfoot, a telltale sign of wind transported snow.
    • Cracking and collapsing or "whumpfs" are red flags, indicating unstable snow.
    • While the wind slabs formed yesterday are likely small, a ride in even a small avalanche can have serious consequences.
    • Avoid steep slopes or terrain features where small wind slabs have formed, and stay cautious in terrain with weak snow layers at the base.

Snow and Weather

We have generally safe avalanche conditions in the Logan zone. The snowpack has adjusted to the pre-Thanksgiving snow load, but unfortunately, riding conditions are starting to deteriorate. Our snowpack is still relatively shallow, with many obstacles visible above the snow surface. Winds blowing from the west picked up yesterday, so watch for small slabs of wind-drifted snow in upper-elevation terrain. These may sound hollow or feel stiff underfoot. Low avalanche danger does not mean no avalanche danger and taking a ride in even a small avalanche could be quite dangerous and consequential. Look for shaded, sheltered slopes with a weak snow surface for the best riding conditions.

The 8500' Tony Grove Snotel reports 26°F and 19 inches of total snow on the ground. It's 24°F at the 8800' UAC Card Canyon weather station, with 22 inches of total snow.

  • Currently at 9700' at the CSI Logan Peak weather station, it's 24°F and the wind is blowing from the west at 19 mph, with gusts to 29 mph. At 9500' on UAC Paris Peak it's 22°F, and winds are from the west 22 to 27 mph.
  • Expect clear, sunny skies today, a high of 34°F at 8500', and light winds blowing from the west-northwest. The forecast is the same for tomorrow, with slightly warmer temperatures. And the next day.
  • A high-pressure system will control the weather pattern and, for at least the next week, we can expect stable atmospheric conditions with fair weather in the mountains and building haze in the valleys.
