Kernpunkte

Dangerous avalanche conditions exist. Yesterday, clear skies led to observations and reports of several slides. Many were shallow, surface slides. Most notably was a large slide on the east face of Teewinot Mountain which ran full track to near the valley floor and had a reported crown depth in excess of five feet. Similar slides are possible today. Take note of the amount the sun is influencing the snow pack as any extended periods of sunshine in the afternoon will increase the likelihood of these slides on sunlit slopes. Cautious route finding, conservative decision making and the ability to resist peer pressure will all be essential for safe travel in avalanche terrain today.

    The potential for large, destructive avalanches continues to be a concern. These persistent hard slabs lie upon January drought surfaces and could be triggered to depths of two to six feet. A slope could be crossed multiple times before a skier or rider finds the finds a trigger point; previous tracks are not a sign of stability. As the day warms, these slides will become more susceptible to failure on sunlit slopes and could release naturally.

    The chance for backcountry travelers to trigger wet loose sluffs and shallow soft slabs will increase on steep, sunlit aspects as the day warms.

Avalanche Discussion

The high pressure ridge over the area will begin to break down and move east allowing a weak short wave into the region Monday. Patchy areas of light snow will develop through the day with very light accumulation. Winds will become more westerly at 15 miles per hour and mountain temperatures will be in the low 20s. Soft surface slabs will become more difficult to trigger as well as deep persistent slabs two to five feet in depth resting on the weak surfaces from January. Triggering both types of slabs will remain possible. Snow machines or the second person or later on a slope may be necessary to trigger slides. Previous tracks can not be trusted to indicate a slope is safe. The general avalanche danger will be MODERATE.
