Highlights

The avalanche danger today is MODERATE. Backcountry travelers should expect to encounter fresh, unstable slabs of wind drifted snow near treeline and above on slopes that face NW-N-NE-E-SE. Travel in alpine terrain requires the ability to recognize and avoid recent deposits of wind drifted snow. Dry-loose avalanches, or sluffs, are possible in steep terrain on any aspect today. These fast moving sluffs are capable of entraining a lot of snow and can get quickly out of hand in consequential terrain.

    The winds have certainly backed off from Monday's event, but on Tuesday, Westerlies were blowing hard enough to easily transport the new, low density snow. Look for fresh, unstable slabs of wind drifted snow on leeward slopes near treeline and above. Recent deposits of wind drifted snow will be most pronounced on above treeline slopes with a North or Easterly component to their aspect. If you are poking up into alpine terrain, you will need to be able to identify and avoid recently wind loaded slopes. Wind drifts will have a smooth, rounded, and fat appearance.

    The most recent storm under-forecasted and over-delivered, just how we like it! Monday's epic wind event left behind hard, slick crusts on most slopes, even on some Northerly aspects. The new snow is poorly bonded to the old surface. The recent snow is cold, dry, and unconsolidated, and sluffs are running fast and far in steep terrain. These sluffs are entraining enough snow to easily knock a rider off their feet, into trees, or over cliffs. If you are getting into steep terrain today, good sluff management is necessary.

    This video shows sluffing in steep terrain, and the resulting debris pile. This is easily enough snow to push you around.

Special Announcement

Geyser Pass Road: The road is open. Expect fresh drifting. AWD and good tires recommended.

Grooming: Trails have not been groomed since Saturday.

Recent Activity

Chris Lile's party triggered this avalanche in wind-drifted snow on a small test slope. Test slopes like this are a great way to gauge how larger terrain with a similar aspect will behave.

Weather

A cold Northwest flow will keep temperatures well below seasonal norms today. High temperatures at 10,000 ft should reach 12 degrees, with winds blowing 10-15 mph out of the West. Look for mostly cloudy skies today and lingering snow showers, with little to no accumulation. Thursday starts a warming trend, with sunny skies and highs in the mid 20's. The warm-up continues through the weekend and high temperatures could reach the low 40's by Sunday.

General Conditions

Skiing and riding conditions are excellent as Tuesday's sleeper storm dropped 9" inches of fluff, and a few more inches stacked up last night, bringing storm totals to around 13" of cold smoke. The new snow is ultra-blower, and you can certainly feel the bottom on Southerly slopes. Polar aspects will offer a smoother ride today. Monday's epic wind event left hard, slick crusts on most slopes, and the new snow is not well bonded to these firm surfaces. Backcountry riders should be aware that sluffs are running long and fast right now. Westerly winds have had an easy time blowing and drifting the new, low density snow. Fresh, sensitive drifts have formed near treeline and above on Northerly aspects.

Chris Lile was out in Corkscrew Glades yesterday. His party reported significant sluffing, and avalanches involving wind drfted snow.

Pre-Laurel winds are down right now, but nearby Carpenter Ridge at 8,000 ft is showing light Westerlies this morning. 12,000 ft. wind stations at Telluride this morning are showing West winds blowing 5-10 mph.
