Kernpunkte

At the mid and upper elevations two days of strong winds have created surface slabs on a variety of aspects. These slabs are likely to be human triggered in steep wind loaded avalanche starting zones at the upper elevations and could be human triggered in steep terrain and cliff areas at the mid elevations. The snowpack is mostly stable at the lower elevations and avalanches are unlikely.

    Strong northwest winds during the past 24 hours have created soft slabs on leeward aspects up to 18 inches in depth. Strong southwest winds in the previous 24 hours created dense wind slabs on leeward aspects up to 18 inches in depth. In steep terrain the softer slabs are likely to be human triggered today, especially on steep wind loaded aspects at the upper elevations. The denser slabs could be triggered at the upper elevations and in isolated areas at the mid elevations with depths of one to three feet.

Avalanche Discussion

Expect cloud cover to increase overnight and through the day on Wednesday as a Pacific trough approaches the region. Overnight lows in the mountains will be in the low teens before rising into the mid-20s during the day. Northwesterly ridgetop winds will back to the southwest at 10 to 20 miles per hour.On Wednesday, the general avalanche hazard is expected to be MODERATE above 7,500 feet. There, backcountry travelers venturing into steep, wind-loaded terrain could trigger surface slabs with depths of one to three feet. The likelihood of triggering these slides will decrease with a drop in elevation, and avalanches are unlikely below 7,500 feet.
