In sintesi

Areas of MODERATE DANGER exist on all aspects and elevations for new snow avalanches. Human triggered dry sluffs and soft slab avalanches are possible.

An occasional wind drift may be found up high, but these may be more prominent in the lower elevations and foothills.

Sluffing and soft slab avalanches in the new snow are possible on all aspects and at all elevations. Dry point release avalanches may run naturally or with provocation but they generally need starting zone slope angles pushing 40° degrees. These can be well managed through avoidance (what's above you?) and with ski cuts. They may also run fast and far on the buried crusts beneath and then pile up deeply in terrain traps.

Recent Activity

Minor sluffing and an occasional shallow wind drift triggered by ski area control teams.

Snow and Weather

Skies are partly cloudy.

Winds veered to the north and northeast and are blowing 10mph with gusts to 15.

Mountain temperatures are all below zero. 11,000' temps are -10°F. Reynolds Peak at 9400' is a balmy -2°F. Wind chill is -16°F

Snow totals are 10"(0.68"SWE) in upper LCC. 15" was reported mid-canyon.

BCC and PC totals are 6" and 4", respectively (at least in the upper elevations). Greg Gagne reported over 2' of new snow in Porter Fork of Mill Creek Canyon.

Valley and bench totals are 12-20", but that's no secret. The SLC airport set a snowfall record for Feb 3rd with 8.6". The old record of 7" was in 1936.

Skiing and riding conditions are good, if not unusual. (Marla looking down on the traffic of I-80; pc: Mark White)

A quick nod to the SLC National Weather Service: yesterday's storm was well forecast and well messaged. Great work to the meteorologists down here.

Today we'll have partly cloudy skies, light north to northeast winds and temps in the low single digits.

The next storm is under Additional Info, below.

Additional Info

Tree-well immersions and asphyxiation should be on the radar in areas that received the most snow. Frost-bite is of concern. Roof-alanches should also be on the radar in the coming days.

We'll see a break in the action today and tonight before the next storm arrives tomorrow afternoon through Friday. This storm will be quite different: a warm front with heavy, dense snow, warming temperatures, and moderate to strong northwest winds. Upwards of 2' of snow possible by later Friday.
