In sintesi

This morning the avalanche danger will rise to MODERATE on all aspects and elevations. Today's new snowfall may create sensitive storm snow at the mid and upper elevations. This could include long-running sluffs, shallow storm slabs, and isolated areas of wind-drifted snow.

Wet loose avalanches are also possible on all low and mid-elevation slopes where rain and wet snow may be falling on an already wet snow surface. Pay attention to changing conditions and continue to evaluate snow and terrain carefully.

This morning's snow has begun falling on a variety of snow surfaces in the backcountry. Light to moderate snowfall throughout the day may lead to periods of sensitive storm snow.

This will include long-running sluffs on all aspects. Winds should be decreasing but these sluffs could be especially prevalent in wind-drifted terrain features such as ridgelines and cross-loaded gullies. Even a small slide can have serious consequences in big, steep terrain or if you’re above cliffs.

This could also include sensitive storm slabs on upper elevation north facing terrain that harbored dry snow before the storm, and any aspect during periods of highest intensity snowfall. Watch for obvious signs of instability such as cracking and sluffing.

Today it will be important to pay attention to changing conditions such as higher snowfall rates than predicted and elevated winds. Increased snowfall rates or increased winds will mean increased avalanche danger.

This morning's rising temperatures and lack of proper refreeze at low and mid-elevations mean that wet snow or rain could be falling on an already wet snow surface. This could lead to wet loose avalanches on all aspects of the mid and lower elevation bands.

Avoid traveling on or below steep terrain features at these elevations.

The key for today will be to climb to higher elevations where there was a proper refreeze, and you no longer find wet snow underneath today's new snow.

Snow and Weather

This morning, mountain temperatures are in the upper 30s F at trailheads and mid to upper 20s F at ridgelines. Winds are currently westerly and averaging 10-25 mph, with gusts in the upper 30s to 40s mph at most elevations. At the highest elevation gusts are above 60 mph. Snow has lightly begun to fall this morning, with totals between 4-6 inches so far in the Ogden area mountains.

Today, a weak weather system is moving through the area and will bring light to moderate snowfall throughout the morning into the early afternoon. Temperatures will be in the mid to upper 40s F at trailheads and upper 30s F at ridgelines. Winds will shift to west southwesterly and average 5-15 mph with gusts up to 30 mph at the highest ridgelines. The storm totals for this weather system could be 4-8 inches for the Ogden area mountains.

This snow will be falling on a wide-spread of snow surfaces. Most aspects will now possess a firm crust, where the previously wet snow surface had a proper refreeze. The exception will be the upper elevation north facing terrain that still had some soft snow before this storm. Take note of the previous snow surfaces as the snow totals begin to grow.
