AVALANCHE DANGER

Considerable - All Elevations 5,500 to 10,500, All Aspects

General Avalanche Advisory

Avalanche conditions are dangerous. New snow continues to increase the load on persistent weak layers that formed earlier in the season. Humans who venture onto steep avalanche prone slopes are likely to trigger large to very large slab avalanches. These dangerous slides are likely to be un-survivable. Expert snowpack and terrain analysis skills are essential for safe travel in avalanche terrain today.

Today's Avalanche Problems

Persistent Slab
ASPECT/ELEVATION: Everywhere other than S-SW below 7500'
Likely
Large to Very Large
Trend: Steady
DESCRIPTION:  Large to very slab avalanches could be easily triggered by a person on a variety of aspects. These slabs could be three to six feet deep.

Wind Slab
ASPECT/ELEVATION: Everywhere above 7500' or W above 9000'
Possible
Small to Large
Steady trend
DESCRIPTION: In steep terrain above 7,500 feet west to southwest to northwest winds have formed wind slabs on leeward aspects. These slabs could be human triggered. They are likely to be 1 to 3 feet deep. These surface slabs could step down to weak layers deeper in the snowpack and become a large to very large persistent slab avalanche.
