Kernpunkte

The avalanche danger is MODERATE at upper elevations where there are sensitive slabs of wind-drifted snow. The avalanche danger is LOW outside of wind-affected terrain and in the low and mid elevations.

If snowfall is heavier than expected this afternoon, the avalanche danger will increase at mid and upper elevations with avalanches possible in new snow and wind-drifted snow.

Cornices continue to grow in size. Avoid traveling below or along corniced ridgelines as they can break further back than you might expect.

Areas of sensitive slabs of wind-drifted snow can be expected at the upper elevations, especially in open terrain above 9,000'. These wind drifts have been isolated in recent days, but with increasing wind speeds today, I am expecting these drifts to be more widespread. These drifts will be 6-18" thick and they may allow you to get onto the wind slab before cracking, possibly even above you. Watch for signs of wind-drifted snow including dense snow that cracks around your skis or snowboard, as shown below. (Photo from Prescott)

Cornices continue to grow in size and will be sensitive, possibly breaking further back than you anticipate. Give them a wide berth by traveling well-away from corniced ridgelines.

Recent Activity

We received an anonymous observation from Cold Water Canyon that describes an avalanche 3' deep and up to 200' wide. Although it is unclear when this avalanche may have occurred, the observation did capture my attention.

To our south in the Salt Lake mountains, the most notable avalanche involved a catch-and-carry on a Southeast aspect on Little Superior at 10,300'. This involved a fresh wind drift up to 18" thick where the rider was carried for 60' before coming to a stop on top of the snow surface. The avalanche continued for another 800' vertical. Huge thanks to the party involved for the excellent writeup, description, and photos, including the photo below.

Snow and Weather

Temperatures range through the teens and low 20's F winds are from the west/southwest. Winds are generally light below 9,000' with gusts in the teens. As you approach 9,000' winds are stronger, with gusts in the 40's mph at some stations. A trace to 2" of snow fell overnight.

For today, temperatures will climb into the 20's with light to moderate snow throughout the day. Snowfall rates will increase mid-afternoon with possibly 6" of new snowfall expected by sunset. Below about 9,000', the west/southwest winds will remain light with gusts into the teens. Above 9,000' winds will be much stronger with gusts in the 30's and 40's mph.

Snowfall overnight and into Saturday, with snow totals possibly exceeding a foot by later Saturday. Another storm Sunday afternoon into Monday.

Aspects facing south and southwest have a thin sun crust underneath any new snow.
