Steamboat & Flat Tops

You can trigger an avalanche where intense westerly winds drifted snow about 3 feet deep or more on steep slopes at all elevations. Avalanches in the most recent snow could easily be large enough to bury you. Look for and avoid steep drifted slopes below ridges, in gullies, or behind convex rollovers. Northeast, east, and southeast-facing slopes at upper elevations are the most dangerous. However, cross-loaded and open, wind-affected slopes at lower elevations could also be suspected.

Another round of snow beginning tomorrow and lasting through Friday might increase the danger again. If you see cracks in front of you in the snow or hear audible collapses, avoid steep slopes. Make conservative terrain choices and don't travel on or below slopes less than about 35 degrees.
