In sintesi

A CONSIDERABLE avalanche danger exists on steep wind drifted slopes in the upper elevations. Natural avalanches are possible and human triggered avalanches are likely. The danger will be most pronounced on west to north to east facing aspects. A MODERATE danger exists on all other aspects and all aspects of the mid-elevations. Shallow wet push-alanches may be possible at and below 9000'.

Remember that early season conditions exist: traumatic injury is possible with any avalanche involvement.

    Sensitive soft slabs of wind drifted snow will be the number one concern on many aspects at the mid and upper elevations today. Natural avalanches are possible with enough wind loading.

    Don't underestimate the extent of wind drifting and danger in the mid-elevations.

    With this much continued wind, drifts may be found around terrain features even well off the ridgelines and cross-loaded into gullies and depressions.

Special Announcement

Many ski areas are now closed to uphill travel in order to prepare for winter operations. Resort uphill travel policies can be found HERE>.

Mill Creek Canyon Road will be closed November 8-10th for road work.

Recent Activity

Yesterday's only reported activity involved longer running loose snow sluffs in the steepest terrain.

Snow and Weather

There's no rest for the wicked. Another large, churning Pacific storm is on the doorstep and our partners at the SLC National Weather Service have issued a Winter Storm Watch for late tonight through Thursday morning.

Ski area teams reported a touch of rain to near 9000' overnight with some large diameter graupel thrown in for good measure. At least we've started getting battered by the southerly winds! Ahead of the storm, mountain temperatures are near 30°F up high and near 40°F down low. Along the highest elevations, southerly winds howl at 30mph with gusts to 50mph. Take note that even the exposed mid-elevation anemometers are gusting to 50mph as well.

This is an excellent start to the winter. You'll see Mark's summary below. A link to his observation from yesterday is HERE. 2-3' of dense, supportable snow sits as our foundation with more on the way. The Ogden mountains have 12-24" on the ground; the Provo mountains 12-18".

For today, we'll have an intermittent snow shower here and there with mountain temps rising to the mid-30s up high, the mid-40s down low. Winds will be southerly, blowing 30-35mph with gusts to 50, perhaps higher. Snowfall should begin in earnest tomorrow morning with much of the precipitation coming in on a warm, southerly flow. We may see high fluctuating snow levels (7500'-8500') and heavy dense snow until frontal passage on Wednesday afternoon. 12-24"+ is expected through midday Thursday. Strong southerly winds will accompany the snowfall through midday Wednesday.

Additional Info

A Few Things to Remember:

  • Whether you're-hiking, hunting, skiing, boarding, snowshoeing or firing up the snowmachine: be prepared for avalanches
  • Any avalanche can produce serious trauma because of a thin snowpack
  • Hitting rocks and stumps is a real danger. Don't end your season.
  • Treat ski resorts as backcountry terrain and check out the UAC site for resort uphill travel policies

It's never too early to start thinking about avalanches. A few things to consider:

1. Attend USAW and learn more about avalanches and decision making. (scroll down to the bottom of this page for more info and links)

2. Sign up for an avalanche class.

4. Take the all-new online avalanche courses the UAC built for Know Before You Go or take other online courses listed on the KBYG website (Develop skills -> Online Learning).

5. Get your avalanche rescue gear ready for winter. Put fresh batteries in your transceiver and update the firmware. Inspect your shovel and probe. Get your airbag backpack ready by doing a test deployment and update the firmware if it is an electric version.

Sign up for the 15th Annual Utah Snow and Avalanche Workshop (USAW) one night left, November 9th. Sign up and get more info for the second session HERE.

The Avalanche Professional and Ski Patrol Snow and Avalanche Workshop (PROSAW) will be during the day of November 7th. Sign up and get more info HERE. (note - PROSAW will be offered both in-person and virtual).
