Forecast for the Logan Area Mountains

Trent Meisenheimer
Issued by Trent Meisenheimer for
Friday, March 15, 2024
Today, the avalanche danger is CONSIDERABLE across all upper-elevation steep slopes for wind-drifted snow (wind slab) avalanches. The strong northeast wind has created 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 likely.
The avalanche danger could rise to MODERATE on southerly facing slopes during the day for wet snow avalanches.

The UAC is proud to present "To the Hills & Back", a heart-wrenching documentary that delves into the lives of two backcountry skiers, Katie Combaluzier and Adam Campbell, who navigate through the aftermath of separate avalanche tragedies. This film is a testament to human endurance and the transformative power of adversity. Watch it here.
Weather and Snow
Under mostly clear skies, the mountain temperatures are 15-20 °F. The wind blows from the northeast at speeds of 10-20 mph across most of the low to mid-elevation terrain. Higher up on Logan Peak it's a different story as the wind is ripping from the northeast at speeds of 40-50 mph gusting into the 50s and 60s. In the past 24 hours, areas around Logan Peak have picked up roughly 7 inches of new snow. Beaver Mountain picked up 3 inches of new snow. This brings the 48-hour totals to roughly a foot of new snow.
Today, our closed low-pressure system has moved to the south and now spins over the California/Mexico border. As a result, we will be left with mostly sunny skies with temperatures climbing into the 30s and low 40s at about 8,000'. Unfortunately, the northeast wind will continue to wreak havoc, blowing 40-50 mph across the upper elevations.

Avalanche Problem #1
Wind Drifted Snow

Description
The wind has now been blowing at elevated speeds for the past 24 hours now. This morning the latest wind reading on Logan Peak is 47 mph gust 60. This wind combined with roughly a foot of new snow over the past two days has created sensitive soft or hard slabs of wind-drifted snow. Human-triggered avalanches 1-2 feet deep will be likely on wind-loaded slopes (wind slabs).
The tricky part: The wind direction is from the northeast which is not our typical loading pattern. In fact, the wind hardly ever blows from this direction. So, be on guard for unusual wind loading. Remember wind-drifted snow can look wavy, pillowy, or it can be hard and sound hollow like a drum.
Avalanche Problem #2
Wet Snow

Description
Today, with mostly sunny skies, we must keep wet snow avalanches in our minds. It's March, the days are longer, and the sun is strong. South-facing terrain can change rapidly this time of year. Roller balls are the first sign of unstable wet snow. The wild card will be if the wind keeps the snow surface cool enough to off set the strong sunshine keeping the wet activity at bay.
