In sintesi

The avalanche danger for wet avalanches will quickly rise to MODERATE on all aspects other than upper elevation northerly slopes where sunshine and very warm temperatures will create conditions for avalanches involving wet loose snow and possibly wet slabs. Cornices may collapse naturally, possibly avalanching the slope below.

Keep people and pets from underneath steep, snow-covered roofs as roof avalanches can be expected in mountain communities.

Terrain where glide avalanches can occur should be avoided.

Sunshine and very warm temperatures will quickly soften snow surfaces today, with the following wet snow issues:

WET AVALANCHES: These will involve loose, wet snow (such as shown in the photo below from Joey Manship), but larger wet slab avalanches are possible, especially in the low and mid elevations. Once the snow surface becomes unsupportable, it's time to find a cooler aspect or return to the trailhead.

CORNICES: Cornices may calve off naturally, possibly triggering an avalanche on the slope below.

GLIDE AVALANCHES: Full-depth glide releases can again be expected in the usual terrain of Stairs Gulch, Broads Fork, and Mill B South of BCC and upper Porter Fork in MCC. These full-depth and catastrophic natural releases are difficult to forecast and more difficult to survive. The best advice is to simply avoid this terrain for now. A Fatal glide avalanche accident in Stairs Gulch April 2001.

ROOF AVALANCHES - where a roof sheds its snowpack - remain a significant objective hazard in mountain communities. Do not let children play underneath steeper, snowfilled roofs. A roof fatality occurred as recently as April 2023 in the Brighton township where an adult was working (likely) underneath a roof that avalanched on top of them.

Special Announcement

Motorized Users—Please consider taking this 5-minute survey to help researchers better understand avalanche education participation and safety preparedness. Responses are anonymous and confidential.

Our regular daily avalanche forecasts will end this Sunday, April 13. After that, we will issue updates when necessary and publish public observations until May 1.

Recent Activity

Only minor wet loose wet avalanches were reported from Thursday.

Snow and Weather

This Morning: Skies are mostly clear and temperatures are in the low 40's F - about 10° warmer than yesterday morning. Winds are gusting to 20 mph along some upper-elevation ridgelines, with 11,000' gusts in the low 40's mph.

Today: Mostly sunny and very warm, with upper elevation temperatures reaching the 50's F, and even warmer temperatures below. Winds will be from the southwest and slowly increase through the day.

Despite the warm overnight temperatures, clear skies, low humidity, and winds *may* have provided a marginal refreeze this morning. The UAC's Joey Manship was on Lake Peak in White Pine yesterday and reports he was able to find softening snow on south and east aspects in the morning and west aspects early afternoon. Today's window for a supportable snow surface is likely to open and close much sooner than yesterday.

Nikki's Week in Review is available. We hope you've taken advantage of this valuable product Nikki has written each week this past season, and that it has been a regular part of your planning.
