In sintesi

Temperatures are starting out around five degrees warmer than yesterday morning. At the mid and upper elevations, daytime warming will increase the likelihood for skiers and riders to trigger recently developed wind slabs. If extended periods of sunshine occur, natural activity could develop as the day progresses. Warming conditions will also bring about the possibility of wet slides on steep, sunlit slopes. Don’t let recent snowfall, sunshine or the weekend timeframe impair your judgement. Monitor temperatures and the impact of the sun, and have a plan to transition to shaded terrain if snow surfaces start to become saturated. Significant avalanche activity is unlikely at the lower elevations.

    Above 8,000 feet, daytime warming will increase the chance for skiers and riders to trigger wind slabs one to three feet in depth on steep, avalanche-prone slopes. If mostly sunny skies dominate, shedding of the recent snowfall could occur naturally. These slides have the potential to travel long distances and entrain significant amounts of snow in very steep, sustained terrain. Conservative decision making and a close eye on the weather will be essential for safe travel in avalanche terrain.

    The amount of sunshine through the day will be the primary factor for the development of wet slides. Above 8,000 feet, shallow wet sluffs could develop on sunlit aspects as snow surfaces start to dampen. As the day continues to warm, wet slabs involving the recent snowfall could release naturally on sunlit aspects if cloud cover becomes sparse.

Avalanche Discussion

A Pacific low pressure trough and associated cold front will pass through the region on Monday evening and Tuesday. Skies will be mostly clear overnight. Clouds will increase with areas of steady light to moderate snowfall developing by evening. This system will bring 4 to 8 inches of new snow to the mountains by Tuesday evening. On Monday southerly winds will become strong with gusts to 55 miles per hour. Temperatures will rise in to the mid-30s on the summits and to near 50 in the valleys. The general avalanche hazard is expected to be MODERATE above an elevation of 8,000 feet. Areas of unstable snow exist at the higher elevations. Strong southerly winds will impact exposed slopes and ridges. Skiers and riders could trigger large slab avalanches 1 to 3 feet deep in steep avalanche starting zones. The sensitivity of these slabs to human triggers will increase as the day warms. Avalanches are unlikely below an elevation of 8,000 feet where the hazard is expected to be LOW. Tomorrow is a day when conditions can change quickly. Rain showers, warm temperatures and areas of blowing snow are likely to be encountered. Continually reassess conditions and modify travel plans accordingly.
