In sintesi

Avalanches are unlikely today and the danger is Low. Triggering an avalanche 1-3 feet deep in steep upper elevation terrain cannot be ruled out. Remember that “Low” danger does not mean “No” danger.

    Yesterday a snowmobile triggered avalanche was reported on a north aspect at 9,800 feet.  This avalanche failed on weak snow 3 feet below the surface.  All riders involved in the avalanche were unharmed. This incident is a good reminder that despite a generally Low avalanche danger, there still exists the remote possibility of triggering an avalanche in steep upper elevation terrain. The exact location of this avalanche is still to be determined.

    This avalanche highlights the need to remain vigilant, even in times of Low danger.  Remember to only expose one person at a time, use islands of safety and watch your partners when entering into avalanche terrain. The reporting party of this incident did a good job of following safe travel practices and preventing the entire party from injury or burial. Thank you to the party for reporting this avalanche.

Avalanche Discussion

The snowpack structure is poor in many locations. Weak snow near the bottom of the snowpack lingers as a potential problem.  While unlikely, the remote possibility exists for triggering an avalanche on this layer. Snowpit tests continue to show this potential, despite a general lack of activity. The exception to the rule is possible as evidenced by yesterday’s reported avalanche.

As this dry period of weather continues, it is important to track snow surfaces. This will become increasingly important with any measurable precipitation in the forecast. Currently there exists a wide range of surfaces, with weak snow in sheltered locations and sun and wind effect in exposed terrain. Having a good handle on these surfaces and their general distribution will help in anticipating the next round of avalanche activity.
