Forecast for the Abajos Area Mountains

New snow and wind have conspired to form fresh drifts at upper elevations and the avalanche danger is MODERATE on steep, wind drifted slopes. Look for fresh wind drifts on the leeward sides of ridge crests and terrain features. Wind drifts are recognizable by their smooth rounded appearance, and cracking is a sign of instability. On slopes facing the north half of the compass, an isolated possibility exists for an avalanche to fail on a buried persistent weak layer of loose, sugary, faceted snow. Most other terrain has generally LOW danger.

Special Announcements
If you rely on the UAC forecasts each day you get out, consider making a donation during our Spring Awareness Campaign to help us continue providing the avalanche forecasts and education you rely on.
The UAC encourages everyone to follow direction from federal, state, city and county officicals. The following is from Joe Dougherty, spokesman for the Utah Division of Emergency Management:
Though outdoor recreation is still permitted under the governor’s Stay Safe/Stay Home directive, we recommend that people maintain a distance of at least 6 feet.
Be extra cautious to avoid injuries outdoors. We are working with our hospital systems to conserve as much personal protective equipment as possible in case of hospitalizations.
Most outdoor injuries can be prevented. Know the conditions and know your limits so you don’t end up in a hospital.
Weather and Snow
Weather: I don't have any reports from the backcountry to verify yesterday's snow totals but it looks like the mountains picked up about 4" of light snow. Moderate to strong NW winds began to taper off yesterday morning and were relatively light most of the day. Overnight they shifted to the SW blowing in the 10-20 mph range. Today, an upper-level trough on the Pacific Coast will weaken as it moves across the Great Basin and into our region today. We'll see mostly cloudy skies with snow showers likely by this afternoon. Accumulations should be light with 1"-2" possible. Southerly winds will be mostly light and high temps will be in the low 30's. Scattered showers should linger through tonight and into tomorrow with gradually clearing skies throughout the day. Dry and warming conditions extend through midweek.
Snowpack: The new snow will provide a nice refresh, especially on sheltered slopes where soft snow existed prior to the storm Sun exposed slopes are crusty underneath. Fresh wind drifts will be found on leeward slopes, primarily at upper elevations. Deeper in the snowpack, a layer of weak, sugary, faceted snow exists. In isolated areas, a triggered wind drift could step down to this buried weak layer causing a deeper and more dangerous avalanche.
