Kernpunkte

Dangerous conditions exist in the mountains. Deep persistent slab avalanches could be human triggered at the higher elevations. Wind slab avalanches could be human triggered at the mid and upper elevations. Careful snowpack evaluation, cautious route finding and conservative decisions are essential for safe travel in avalanche terrain. Avalanches are unlikely below an elevation of 7,500 feet.

    At the upper elevations (above an elevation of 8,500 feet) large persistent slab avalanches with depths to four feet could be human triggered on shaded aspects. These dangerous slabs can have crowns that break high in the starting zones and propagate into adjacent slide paths. Although these slabs could be triggered by the weight of a single person multiple tracks on a suspect slope should not be interpreted to be an indication of stability. Large triggers like snowmachines are more likely to trigger one of these dangerous slabs.

    Wind slabs formed by west-southwest to west-northwest winds could be human triggered at the mid and upper elevations with depths to two feet. These slabs could fail on density differences, sun crusts, or faceted snow.

Avalanche Discussion

( Discussion is generated from the previous day's afternoon forecast. )Skies are expected to remain cloudy overnight and into the day. Several inches of light density snow accumulation are possible in the mountains. Overnight lows will be near 10 degrees below zero. Daytime highs will rise into the single digits above zero. Winds will be light at 10 to 15 miles per hour and veer to the northwest.The general avalanche hazard will continue to be CONSIDERABLE at the higher elevations. Dangerous deep slabs three to five feet in depth could be triggered by the weight of a single person. These slabs are unpredictable and could release after having been previously tracked by skiers or riders. If triggered these slide are likely to be unsurvivable. Smaller wind slabs with depths from one to three feet could also be human triggered in steep wind loaded avalanche starting zones at the mid and upper elevations. The general avalanche hazard is expected to be MODERATE at the mid elevations and LOW below an elevation of 7,500 feet.
