Points saillants

Areas of MODERATE avalanche danger exist in the backcountry.

You can still trigger lingering soft and hard slabs in isolated terrain, particularly in the upper elevations. Shallow dry and wet loose snow sluffs may also be expected in typical steep terrain.

Good travel habits save lives. Make a plan. Keep an eye on each other.

The avalanche danger will be on the rise over the next few days in lockstep with this next wet, warm, and windy storm.

Pockets of soft and hard slabs of wind drifted snow exist in the upper elevations on many aspects. These may be increasingly stubborn to trigger, but don't rule out triggering one of these in steep, localized terrain features. In his field work, Greg Gagne and his partner were finding hard slabs of wind drifted snow reactive in snow tests and elected to remain on low angle terrain.

CORNICES are currently large and growing and may be particularly sensitive and tender during periods of sun, warm temperatures and strong winds. Give cornices, and the edges of cornices a wide berth as they often break farther back than expected. Limit your exposure to slopes below cornices. Cornices are signs that a slope has been wind loaded and a cornice fall could trigger a larger slab of wind-drifted snow below.

Special Announcement

The UAC is currently working with the operation involved in Thursday's fatal avalanche in the Uintas to prepare a report. Please be patient as we sort out the details of this complicated incident. A preliminary report is available HERE.

Please consider donating to the spring campaign to help our team implement innovative tools and better provide you with the information you rely on.

Recent Activity

Ski area avalanche teams yesterday reported triggering shallow soft slabs as well as both wet loose and dry loose sluffs in steeper terrain.

Heading to Provo? It's worth checking out this very close call from Saturday.

Snow and Weather

Skies are partly to mostly cloudy. Winds are light from the west. Mountain temperatures are in the upper teens and low 20s.

Snow showers added to 2-5" of graupel and medium density snow through mid-morning yesterday.

Today will be very spring-like with periods of sun, periods of snow showers. There is some chance of lightning/thunder in the afternoon. Mountain temps rise to the mid-20s up high, the mid-30s down low. Winds are expected to be light from the west.

I view today as another day of rest ahead of the next atmospheric river event, due to impact Utah tomorrow afternoon. Winds will ramp up to strong from the southwest with rain up to 8000' in the afternoon. Warm wet and windy again Tues afternoon through Wednesday afternoon before, mercifully, the cold front arrives. All told, I would expect upwards of 1.5-2.0" of precipitation and 12-18" of snow through early Thursday.

Additional Info

While not directly avalanche problems, tree wells, "snow immersion suffocation" is a backcountry danger worth noting. Read more HERE. With so much snow on rooftops in mountain communities, roof avalanches will be a significant hazard as the sun warms roofs in mountain neighborhoods. Children playing and adults shoveling solo are especially vulnerable to this hazard.
