Weather and Snow
It is currently snowing at the top of the Cottonwood Canyons. This low density snow should clear out with sunrise. Temperatures are in the low 30's F at the trailheads and in the mid 20's F at the higher elevations. Winds are westerly in the mid teens MPH gusting to the low 20's MPH.
Today, mostly cloudy. Temperatures will be 36-40 F. Winds at the 9000' ridgelines will blow from the southwest 15 gusting to 25 MPH and at the 11,000' ridgelines 20 gusting to 35 MPH.
The National Weather Service is forecasting an atmospheric river event to hit the Wasatch Range mid-day Tuesday through Thursday with 2.25"-3.25" of water and up to 36" of snow.

There were reports of roof slides in Big Cottonwood Canyon neighborhoods yesterday.

Avalanche Problem #1
Persistent Weak Layer
Type
Location
Likelihood
Size
Description
The persistent weak layer (PWL) that formed in mid-November and was subsequently buried is still distinguishable in snowpits at all aspects and elevations. Yesterday at the top of Little Cottonwood Canyon, my partner and I were still seeing propagation with extended column tests. This buried weak layer of facets is suspect and I would not travel into steep terrain without conducting a series of snowpack tests and only exposing one person to a slope at a time.
Most avalanche activity on this layer has been on northerly facing terrain. This layer DOES exist in other places as I found yesterday, and it could begin producing avalanches when it gets loaded by a series of storms this week.
Avalanche Problem #2
Wet Snow
Type
Location
Likelihood
Size
Description
With warm temperatures forecasted today and some lower elevation areas remaining above freezing for the last twelve hours I would not be surprised to see some wet loose activity with any hint of sun.
Stay away from any roof that is still holding snow as it may release and cause injury to adults. Be especially watchful of children playing near buildings.
