Ogden Avalanche Advisory

Forecaster: Bruce Tremper


This will be our last week of morning forecasts. After Easter Sunday, we will do intermittent afternoon updates until near the end of April or conditions become very benign, whichever comes first.


Danger by aspect and elevation on slopes approaching 35° or steeper.

Danger Rose Tutorial

The avalanche danger today is mostly LOW but you may find pockets where you could trigger a shallow wind drift on a steep slope or any steep slope that is getting wet from the heat of the sun.


The April Fool’s Day storm is well named. Most places in the Wasatch Range got fooled--receiving either no snow or perhaps an inch, and that came overnight instead of yesterday. As usual, the Cottonwood Canyons were the only places with more than a dusting where the storm piled up 3-4 inches in upper Big Cottonwood and 4-7 inches in upper Little Cottonwood.

Most places are dust-on-crust with the crust being very stout--several inches thick--when the pre-existing, gloppy snow froze solid with the arrival of the cold front on Sunday morning. Riding conditions are not too bad on very gentle slopes but on the steep slopes you are chattering on the old crust and bouncing off various forms of frozen drool from the extremely warm temperatures all week.


No avalanche activity from yesterday.


      Over the next 24 hours.

Taking a slide-for-life on the stout crusts is probably the largest hazard today unless you are in the upper Cottonwood Canyons where there is enough new snow to give you a better grip.

Avalanche-wise, the only show in town will likely be localized wind drifts of the new snow, which will be mostly soft and shallow. They will be easy to recognize and manage. As usual, avoid steep slopes with recent wind drifts, which you will find mostly along the upper elevation ridges.


A few clouds coming out of the north this morning should clear out and it should be a mostly sunny day. Temperatures are in the mid teens this morning but should warm up to near freezing. The ridge top wind should blow 15 mph from the north. We have mostly clear skies and warming temperatures for the next several days but we should get stronger winds and perhaps a snowflake or two from a passing, nearby storm on Wednesday and Thursday.


If you trigger an avalanche in the backcountry - especially if you are adjacent to a ski area – please call the following teams to alert them to the slide and whether anyone is missing or not. Rescue teams can be exposed to significant hazard when responding to avalanches, and do not want to do so when unneeded. Thanks.
