Forecast for the Salt Lake Area Mountains

Saturday morning, February 22, 2020
The avalanche danger is LOW. The three things to watch for today are (1) pockets of isolated wind slabs in the upper elevations, (2) sluffing in the upper elevation northern aspects and (3) small, wet, loose avalanches on southeast through west-facing aspects.

Remember a low avalanche danger, doesn’t mean “no avalanche danger”. Continue to evaluate snow and terrain carefully.

Weather and Snow
This morning, temperatures range through the 20's F, with a temperature inversion at some low-elevation trailheads with temperatures in the mid-teens. Winds are westerly, southwesterly and generally light averaging 5-15 mph below 10,000'. At the highest elevation ridgetops gusts are in the low 30s mph.
Today, the high pressure system will gradually shift east. This will bring mostly cloudy skies and warm temperatures, in the upper 30s to low 40s F. Winds will continue to be west southwesterly and average 5-15 mph with gusts below 25 mph at mid-elevations. Upper elevation ridgelines will average 10-20 mph with gusts up to 30 mph.
Looking forward, a storm system will be tracking south of us tonight and could bring up to an inch of snow to the Central Wasatch.
Recent Avalanches
Two avalanches were reported in the backcountry yesterday.
The first was a skier triggered soft slab avalanche on a Northeast aspect at 10400 feet on the Coalpit Headwall. This soft slab broke 35 feet wide and ran about 600 feet. One person was caught, but no one was buried. You can find a great first-person account HERE.
The second was a serious of intentional skier triggered wind slabs on an East aspect at 9400 feet in Hogum. These avalanches were 18 inches deep and failed on the Feburary 7th crust, and broke 30 feet wide. You can find the full report HERE.

Description
Today, the overall avalanche danger is LOW. This means that human-triggered avalanches are unlikely, but small avalanches in isolated areas are possible.
Today I would watch for:
  1. Small pockets of recent-wind drifted snow in isolated terrain features, such as ridgelines and cross-loaded gullies. Avoid terrain features with obvious signs of wind-drifted snow.
  2. Shallow sluffing in the upper 2-6" of snow on steep north-facing terrain. While these may not be large, they are enough to knock you off your feet and sweep you through consequential terrain.
  3. Small, wet, loose avalanches on southeast through west-facing terrain if the sun comes out today. While we should primarily have cloudy skies today, the clouds may break late morning and offer a few hours of sun. The sun in combination with the warm temperatures could lead to some loose wet avalanches on solar aspects.
With a LOW danger, it is reasonable to venture into more radical terrain, but always consider the consequences of an avalanche. Even a very small avalanche can be deadly in certain terrain.
Continue to maintain safe travel habits; this means exposing one person at a time to avalanche terrain and having someone watch them from a safe location.
