Kernpunkte

The avalanche danger is MODERATE on steep, wind drifted mid and upper elevation slopes, where human triggered slides are possible today. The danger could rise from LOW to MODERATE for wet loose sluffs if the clouds thin or the sun comes out. Avoid avalanche runout zones and small terrain traps even at the low elevations.

Want a great powder day? Seek wind sheltered slopes early in the day while the snow is cold. It could be a dynamic day, but with careful snowpack evaluation and constant assessment for heating, there are lots of safer options for touring and riding today.

    The drifts of wind blown snow that formed yesterday and overnight will be the main danger today. While the drifts will be most widespread at the highest elevations, drifts can also be found well off ridge lines, at the mid elevations and cross loaded around terrain features. Signs of wind drifts include cracking of the snow and looking for and avoiding smooth, rounded pillows of snow.

    There will be a whole new batch of cornices along the higher ridge lines, and they may break from a distance. Stay well back from corniced edges when traveling on ridge lines and avoid travel beneath them.

    Today, I expect partly sunny skies in the Ogden area mountains. When the sun comes out or the clouds thin...the surface snow will almost instantly heat, and wet loose avalanches and shallow wet slabs will become easy to trigger. Thinning of the clouds means the snow will heat on all aspects and elevations except steep, upper elevation northerly facing slopes. Direct sun will heat steep, sunny slopes.

    Clues will be abundant if the snow heats - you will feel the hot April sun, the snow becomes sticky or damp, pinwheels or swarms of roller balls race downhill, you’re triggering small sluffs or the snow is falling off rocks and trees. Danger for wet sluffs can rise from LOW to MODERATE in minutes. Wet avalanche debris piles up instead of spreading out, and even small slides can deposit 4 feet of cement like debris. Get off steep slopes, head to low angle slopes and avoid travel beneath steep slopes and avalanche run out zones. Have a game plan for your exit out of the backcountry.

    The old wet snow at the mid and lower elevations of the Ogden area mountains is still saturated, and any collapsing is a clue that it is still weak, and steep slopes should be avoided.

    Glide avalanches are difficult to forecast as they seem to happen at unpredictable times. A good dose of rain yesterday following a long stretch of above freezing temperatures day and night are prime conditions for these avalanches to occur. Before releasing, the snowpack typically produces large, visible cracks in the snow which tell us where these avalanches can occur.

    They often happen where the snowpack rests on top of rock slabs or smooth surfaces. Common places to find these cracks and glide avalanches are on the steep Ben Lomond faces. Knowing when they will occur is very difficult to forecast.

Recent Activity

No new avalanches reported from the Ogden area mountains.

Special Announcement

Daily early morning avalanche forecasts will end Sunday, April 14. We will issue early morning forecasts on Friday, Saturday, and Sunday of Easter weekend (April 19-20). Throughout the rest of April, we will issue intermittent updates with any snowfall and we will continue posting observations.

Our final podcast for the season has been released HERE. Low Danger - A Story in 5 Parts. Thanks much to our producer Benjamin Bombard and our sponsors Arva, Prival, and 2nd Tracks Sports.

Thanks so much to everyone who supported our spring fundraiser. We exceeded our goals. The UAC could not exist without your support.

Snow and Weather

A nice little refresh, with cold wintery temperatures. The Ogden area mountains received about 8" of snow, with storm water content almost an inch in places (including both rain and snow). Temperatures have cooled into the mid to low twenties, with teens along the high ridge lines. Overnight, the northwesterly winds were strong, averaging 25 to 30 mph along the highest ridge lines, with gusts to 50 mph.

Today: Under partly sunny skies, a few convective showers this afternoon will produce another trace to 2” of snow. This morning’s northwesterly winds should continue to decrease, though averages of 20 to 30 mph, with gusts to 40 mph could still occur along the high ridge lines. Temperatures will warm iinto the low 30s at 8,500’ and into the mid 20s along the highest ridges.
