New snow avalanches may still be triggered on all aspects and elevations. Natural avalanches are possible today as well.

Some of these may be up to 1-2' deep today. These avalanches may be particularly sensitive on steep west to north to east facing slopes, even in the low elevation bands. One might even trigger them at a distance. The snow surfaces prior to the storm were particularly weak with what we call near surface facets...along with carpets of surface hoar (the wintertime equivalent of dew).

This was a significant loading event to test the reactivity of our older buried weak layers from November. These avalanches certainly loom as deep and destructive and this terrain should be avoided for now. Any new snow avalanche may step down into this older layering 2-4' deep.

Recent Activity

The Provo mountains experienced a widespread and dangerous avalanche cycle yesterday and conditions remain very dangerous.

Yesterday at Sundance resort, a skier went out of bound to chase a lost ski. In this out of bounds area, he likely triggered at least one avalanche that came down from above and completely buried him. The ski patrol located him and allowed him to free himself of the debris. He was below steep northeast facing terrain at 7600' in a place called the Pipeline, a notorious terrain trap.

A very close call.

Snow and Weather

Skies are overcast with light snow falling across the range.

Winds are light from the southwest. Mountain temperatures are in the teens to low 20s.

Sundance resort picked up 24" (2.52" SWE). This amount of SWE is over 1/4 of their total SWE since October 1st. Timp divide and the south fork picked up 12-20" of snow.

Skies should trend mostly and perhaps partly cloudy today with mountain temps still cool in the teens. Winds will remain light from the southwest.

The Outlook:

Another storm arrives but dives well south of us for the first part of the week. Another storm sets up mid week well to the west of us that will pummel us by strong southwest winds. It eventually ejects inland and moves overhead Friday into the weekend.
