Kernpunkte

Today, there is a MODERATE avalanche danger on upper-elevation slopes where it will be possible to trigger wind-drifted snow avalanches near ridgelines and terrain features. The avalanche danger may rise to MODERATE on other aspects and elevations later this afternoon with the approach of a new storm that is forecast to bring increased wind speeds, new snow and dropping temperatures to the area.

Sustained strong winds have created stubborn slabs of wind-drifted snow on upper-elevation slopes and terrain features. These drifts could be 1'-3' deep and up to 150' wide. Watch for and avoid signs of wind-drifted snow; such as pillow-shaped deposits and rounded smooth areas of snow. Cracking in new wind-drifted snow is a sign that things are unstable and steeper slopes should be avoided. Cornices are signs of wind loading leeward features. Any cornice failure could trigger an avalanche on the slope below.

Elevated winds should keep the wet snow at bay today in upper elevations. Many locations have not seen a refreeze since Saturday morning and these lower elevation slopes are places where you may see wet avalanche activity. Wet snow is the easiest avalanche problem to avoid. Look for and avoid signs that the snow surface is becoming wet; such as rollerballs and pinwheels. If you are sinking into the snow past your boot tops it is time to gain elevation and find dryer snow. Any wet loose avalanches may trigger larger slab avalanches. This problem will decrease with colder temperatures moving in later this afternoon.

Recent Activity

There were reports of wind-drifted snow avalanches on leeward aspects in the Ogden Area yesterday. Read all observations HERE.

Snow and Weather

This morning, under partly cloudy skies trailhead temperatures are in the mid 30's°F with some stations in the low 40's °F, and ridgetop temperatures in the mid 20's °F. Winds are blowing from the southwest 15 gusting to 35 MPH at mid-elevations, and westerly 35 gusting to 40 MPH at 9,000'.

Today, look for increasing clouds, winds blowing from the west-southwest 25 gusting to 35 MPH at the 8,000' ridgelines and 35 gusting to 50 MPH at the 9,000' ridgelines. Temperatures should be 39°- 42°F with a freezing level dropping throughout the day. Areas favored by southwest flow could see 1"-3" of snow and .10"-.15" of water by early evening. The frontal passage is forecast to come through around midnight with a drop in temperatures, and an increase in wind speeds with gusts up to 100 MPH, and widespread snowfall overnight.

Our Partners at the National Weather Service have issued a Winter Storm Warning effective from 11AM this morning through 11PM Tuesday night with 10"-20" of snow expected and gusty winds at higher elevations. Read more HERE.

Yesterday, there were observations of melt-freeze crusts on solar aspects and weak faceted surface snow on the northerlies. There was also snow being transported across the highest ridgelines starting to form stiffer wind drifts and these increased winds were starting to break down some of the surface hoar and near-surface facets that were observed earlier in the weekend. On shaded aspects, there is still soft snow. If you move into steeper terrain, remember that even a loose-dry avalanche can travel far. Have an escape plan if loose surface snow picks up more speed as it can be more than enough mass to carry you off your feet.
