Lo esencial

The avalanche danger will rise to CONSIDERABLE this afternoon with daytime warming and natural wet snow avalanches are possible on low and mid elevation slopes. Stay off of and out from underneath steep terrain especially later in the afternoon. In upper elevation terrain the avalanche danger is MODERATE where it is possible that a human will trigger a wind-drifted snow avalanche that may fail on a layer of buried facets or on a new/old snow interface.

Lower angle shaded meadows are the best place to find soft turns and stay out of avalanche terrain right now. Start and finish early to avoid the wet snow problem.

A variety of persistent weak layers are still being found on mid and upper elevation northwest-north-east facing slopes. These buried weak layers are variable and make for a complex problem. Thinner, rockier spots, and areas that avalanched earlier in the season are more likely to be places where you could trigger an avalanche failing on a buried layer of facets. We are not done with this buried persistent weak layer quite yet and as much as the mindset in late February typically turns to open-season, it's not that type of season. Give this snowpack some time to settle into its spring coat.

Most weather stations in the Ogden Region have not had a refreeze since yesterday morning. The snowpack in the mid and lower elevation terrain out of the wind zone may be saturated and the chance of triggering a gouging wet snow avalanche will increase with warming temperatures. Areas with long run out zones where avalanches could start as dry snow avalanches and turn into wet snow avalanches may overrun the snow line and even people not traveling in starting zones could be susceptible to avalanches. Avoid being underneath avalanche terrain on mid and lower elevation slopes, particularly during the heat of the day.

With increased wind speeds overnight, there will be drifting snow in mid and higher elevation terrain. Look for and avoid slopes with overhanging cornices and pillowy areas of shiny snow. If you see signs such as cracking and collapsing within the wind-drifted snow then you may be able to trigger avalanches in steep terrain (greater than 30°). Any slope involving wind-drifted snow on a buried layer of facets will be deeper and more likely to bury a human.

Recent Activity

Yesterday, we had reports of wind drifting at the higher elevations, greenhousing, rollerballs and a warming snow surface in lower elevation terrain. There was a report of a shallow wind-drifted avalanche in North Fork, and reports of collapsing in mid-elevation terrain. This is a sign that the snow pack is still settling out. If you hear or feel signs of collapsing then back off of steep terrain. Check out all observations and avalanches HERE.

Snow and Weather

Currently, under partly cloudy skies temperatures are in the high 30's °F. Winds are blowing from the southwest in the teen's gusting to the 20's MPH at the lower ridgelines and from the west in the 20's gusting to the high 30's MPH at the highest ridgelines. There was a trace of precipitation last night in some mountain locations. Today, look for partly cloudy skies with high clouds. Temperatures will be in the high 40's to low 50's °F, with winds blowing from the west-southwest 10 gusting to 20 MPH at the lower ridgelines and from the west 30 gusting to 40 MPH at the highest ridgelines. There is a chance of precipitation today with a freezing level hovering around 9,000' and rising through the afternoon hours.

UAC forecaster Nikki Champion and many observers reported a snow surface that is worn out where you'll find a mix of crusts, damp heat affected snow in the lower elevations or wind-affected snow in the mid and higher elevation terrain. There are still soft turns to be had in protected areas out of the wind zone.
