In sintesi

A HIGH AVALANCHE DANGER currently exists in the Ogden area mountains. Natural and human triggered avalanches in the new snow are very likely in steep terrain of all aspects. The danger will probably peak this morning.

Heavy snowfall and strong winds over the past few days have created a layered and conditionally unstable snowpack. Caution is essential today on all aspects and elevations.

It just keeps snowing. High snowfall rates this morning will lead to very sensitive loose dry and soft slab avalanches in the steepest terrain this morning. Natural loose sluffs are reported as of 6am. Avoid avalanche terrain this morning. This includes runout zones.

The snowpack is more rich, complex, and interesting than I want it to be right now. Avalanches may fail within the new snow or at the new snow/old snow interface (2-4' down) as we saw near the Ant Knolls above Heber/Midway on Saturday. It has also been reported that some new snow avalanches have then stepped down to this older interface from last week.

I plan to stick to low angle slopes until the snowpack stabilizes.

New and old soft slabs 1-2'+ deep of wind drifted snow can be triggered in steep terrain today, particularly on steep north to east to south facing slopes at the mid and upper elevations. Long time and trusted backcountry observer Andy Paradis well described the situation yesterday, "Today's snow plus multiple different loading directions created sort of a complex snowpack that is not visually obvious." It'll be key to avoid recently wind drifted slopes today.

Special Announcement

We are in the process of finalizing a report about the March 9th avalanche fatality in the Uintas. Thank you for your patience, and we will publish the final report in coming days.

Thank you to everyone who donated to our Spring Campaign. We appreciate your support and look forward to creating new tools to help you stay safe in the backcountry.

Recent Activity

We didn't hear of any avalanche activity yesterday. That will change for today.

Snow and Weather

The Ogden skyline has seen radical snowfall rates with the lake effect this morning, with ski patrol teams reporting 20-24" of low density snow overnight! Winds are moderate at the mid and upper elevations out of the west. Temps are in the single digits and low teens.

We should be seeing "peak" snowfall and winds this morning. We'll start to dry out (if only for a day or two) and possibly see a touch of blue by afternoon. Winds will lose steam and average 15mph along the high ridgelines.

Tuesday will be a bit of a break ahead of the next prolonged storm system that will bring at-times heavy snowfall Wednesday afternoon through Friday. 1-2' can be expected. The next storm is forecast for late weekend.
