Good Morning. This is Ethan Greene with the
Well it’s only the eve of The Ides of March, but today you may still want to heed the soothsayer’s warning. Last night under mostly cloudy skies temperatures dipped into the low to mid 40’s at 8,000’ and the relative humidity was near 50%. We have already begun to cool this morning, but the free-air freezing level is about 11,000’. The winds have been from the south and southwest in the 15 mph range with gusts in the 30’s. Along the most exposed ridgelines wind speeds are in the 25 mph range with gusts in the 50’s.
The snow surface has been freezing each night this week, but with very warm overnight lows and increasing humidity the snow surface may be soggy this morning below about 9,000’.
Yesterday 8,000’ temperatures

Today and tomorrow are going to be days of transition. It is quite warm this morning, but clouds, gusty winds, and a cooling trend will be attempting to offset our early spring weather. With yesterday’s natural activity, it is probably a good day to avoid traveling under steep rock slabs or any slope with a large cornices. Deep slab avalanche are possible in the same areas that have been problematic all year. Those are thin snowpack areas that are steeper than about 35 degrees and face north, northeast, east and southeast.
As always, you should get out early and get off of and out from underneath any steep slope when it gets wet and soggy, but today these conditions may occur earlier than you expect.
Bottom Line (SLC,
The avalanche danger today is CONSIDERABLE on and underneath steep slopes that have had a thin snowpack most of the year. Point release avalanches and cornice fall could trigger dangerous deep slab avalanches. In areas less than about 35 degrees in steepness and not threatened from above the avalanche danger is generally MODERATE.
The weather will be changing
