Snow: As of 6 a.m. an additional 4-5 inches of snow fell overnight and it is still snowing. Snowfall really picked up in upper Little Cottonwood Canyon this morning at 2-3 inches/hour with a total of 8 inches overnight. Total snowfall this week is 12-21 inches (0.75-1.85 inches of water) with upper parts of the Cottonwood Canyons receiving the most.
This morning temperatures range from the mid teens F to the mid 20s F. Winds were mostly light yesterday but increased some yesterday afternoon and overnight. This morning winds are still a bit gusty. They are averaging 10-15 mph from the south-southwest and gusting 20-35 mph.
Today, steady snowfall should continue into mid morning and then becoming more intermittent bringing another 3-5 inches of snow. Cloudy skies will prevent temperatures from warming beyond the upper 20s F. Winds should calm later this morning when they shift to the northwest.
The new snow is generally right side up on wind-sheltered slopes - meaning the upper layers are lighter and lower layers are denser HOWEVER gusty winds this morning created a denser layer of snow on top of lighter snow.
HEADS UP: With snow falling at a rate of 2-3 inches per hour this morning in upper Little Cottonwood Canyon, we haven't received any reports of avalanches yet, but I expect some natural avalanches in the new snow are happening.
there were 8 soft slab avalanches
triggered in the new snow. All were about a foot deep and 25-125 feet wide and generally occurring above 9500 feet. Most occurred on northerly facing slopes, but two occurred on southerly facing slopes where the new snow had not bonded to an ice crust underneath.
Many of them likely failed on some graupel that fell early this week. Below is a photo of one I triggered on Little Water Peak
