Highlights

Today, the avalanche danger is MODERATE across all mid and upper-elevation steep slopes for wind-drifted snow (wind slab) avalanches. The strong northeast wind will create shallow, soft, or hard slabs of wind-drifted snow that could be sensitive to the weight of a rider. Human-triggered avalanches 1-2 feet deep are possible. Out of the wind-drifted snow problem, you will find a LOW avalanche danger where 4-6 inches of new snow sits over a firm base.

    The northeast wind is currently blowing 15-25 mph gusting to 40 on Logan Peak and could reach higher speeds later today. This wind, combined with 4-6 inches of new snow, will create shallow, soft, or hard slabs of wind-drifted snow (wind slabs). Human-triggered avalanches 1-2 feet deep will be possible on wind-loaded slopes.

    The tricky part: Northeast wind is not our typical loading pattern. In fact, the wind hardly ever blows from this direction. So, be on guard for unusual loading patterns, look for snow drifted by the wind, and avoid those areas. Remember wind-drifted snow can look wavy, pillowy, or sound hollow like a drum (See picture. Can you spot the wind-drifted snow?).

    The excellent news: Lose the wind and lose the problem. Outside of slopes being loaded by the wind, you will find a LOW avalanche danger. Yesterday, we rode miles of terrain in the meadows and had a blast.

Snow and Weather

Under cloudy skies, it's snowing in some locations of the Logan Mountains. Beaver Mountain web cam shows the situation. This brings snow totals for the past 48 hours to roughly 4-6 inches of new snow (0.30-0.90 swe). Mountain temperatures range from 15-22 °F. Winds from the northeast are blowing 15-25 mph, gusting into the 30s across the upper elevations.

Today, as a closed low-pressure system parks and spins over Sin City we will see wrap-around moisture on a northeasterly flow. Clouds will be streaming overhead and in some areas there will be bands of snowfall at times. Unfortunately, nothing good ever comes from an easterly flow. The National Weather Service has announced a high wind warning for areas of northern Utah. The northeast wind could reach speeds of 20-30 mph or greater with gusts into the 30s and 40s by this afternoon.
