Lo esencial

The avalanche danger is Considerable at all elevations today. Dangerous conditions exist. Warm overnight temperatures combined with poor snowpack structure are making wet loose avalanches likely and wet slab avalanches possible. Cornice falls are also a possibility today. Natural avalanches are possible and human triggered avalanches are likely. Be aware of terrain above you, as avalanches will have the potential to run through multiple elevation bands. Weak unsupportable snow will make travel difficult in the mountains today.

    Wet loose avalanches will be likely in steep terrain today. These may occur naturally and will be easily triggered by skiers and riders. Two consecutive nights of minimal to no freezing in the mountains have created conditions ripe for triggering avalanches. The likelihood of triggering will increase as temperatures rise and the sun impacts snow surfaces. These avalanches have the potential to gouge down into deeper weak layers and entrain significant amounts of snow.

    Weak layers that formed in January and February sit below slabs that have formed in March. These weak layers and slabs have become saturated with water in many locations and hold the potential to produce large and destructive avalanches. Slab depths are in the 1-3 foot range and have the potential to gouge into deeper weak layers. In the higher elevations slab avalanches may initially be dry but will become wet while moving downslope.

Avalanche Discussion

Temperatures are to stay above freezing for the third night in a row this evening. Highs tomorrow will reach into the upper forties in upper elevation terrain. Snow near high peaks and summits should stay cooler, due to southwest winds averaging around 20 miles per hour. In the valleys, expect mild inversions with lows near thirty and highs in the sixties. Again, clouds will be present but conditions will be mostly sunny. The general avalanche danger will remain Considerable at all elevations on Monday. Another warm day and a weak snowpack demands respect. Although stable snow can be found early in the morning, the snowpack will be unstable in most terrain by mid-morning. Wet slides could be human triggered or release naturally. The potential exists for avalanches to become large as they descend and run long distances. Recreationalists are encouraged to get in and out of the mountains by mid- morning or to wait until the weather pattern becomes a melt-freeze regime.
