In sintesi
The General Avalanche Hazard is LOW at all elevations in the early morning hours and will rapidly increase to MODERATE as surface crusts break down. If clear skies prevail throughout the day, the hazard will continue to rise to CONSIDERABLE. The potential for dangerous, natural wet-loose and wet-slab avalanche activity will increase on steep, snow-covered slopes as the day progresses. In addition, the possibility for human-trigger, dry-slab avalanches on very steep, shaded aspects above 9,000 feet will also rise with daily warming. These slabs, either wet or dry, are likely to fail on layers of weak, faceted snow that persist within or at the base of the snowpack. With temperatures starting off 5 degrees warmer than yesterday, backcountry travelers should be off of sunlit aspects by late morning.
Avalanche Discussion
Cloud cover is expected to decrease overnight, with mostly clear skies by Monday morning. Warm, dry conditions should remain through Monday evening. Overnight lows are projected to be near 20 at all elevations before rising into the low 40s in the mountains and near 50 in the valley on Monday. Westerly ridgecrest winds are forecasted to range from 10 to 20 mph.The General Avalanche Hazard is expected to be LOW at all elevations in the early morning hours and will rapidly rise through MODERATE to CONSIDERABLE as surface crusts break down.
