In sintesi

Spring is once again gaining ground on the higher elevation, winter snowpack. Temperatures are starting out around 5 degrees warmer than yesterday morning. Above 8,000 feet, wet slides will be the primary concern as temperatures warm and cloud cover decreases. Shallow, wet loose slides could develop on sunlit aspects, and wet slabs might release naturally during the heat of the day. In very steep, avalanche-prone terrain above 9,000 feet that has not undergone significant warming, the chance for skiers and riders to trigger small to large wind slabs will also be on the increase. Daytime warming will also raise the likelihood of cornice failures. Get an early start, monitor the effect that warming temperatures and sunshine have on the snowpack, and have a plan to transition to cooler terrain or be willing to come back another day. Below 8,000 feet, the snowpack is mostly stable where it still exists.

    Both wet slabs and wet loose slides will become possible today. Temperatures remained above freezing overnight in many areas up to 8,500 feet, and some cloud cover through the night limited radiational cooling. Wet loose slides will pose their greatest threat in confined terrain and very steep couloirs where small slides can quickly grow and entrain significant amounts of snow. Be mindful of both the terrain that you are on and the terrain above you. Wet slabs might develop on slopes where old, dry snow is beginning to thaw for the first time. Breaking through once supportable crusts is a good prompt to alter your travel plans.

Avalanche Discussion

( Discussion is generated from the previous day's afternoon forecast. )As the aforementioned upper level low pressure system tracks eastward towards the four corners, a few scattered showers could develop in the Southwest Trails forecast zone. This weather pattern will result in more cloud cover down south and partly cloudy skies up north. Overnight lows in the mountains will be in the mid-20s before rising to near 40 in the afternoon. Easterly ridgetop winds will back to the northeast and increase to 20 to 30 miles per hour.The general avalanche hazard is expected to be Moderate above 9,000 feet on Friday. Up there, skiers and riders might be able to trigger recently developed wind slabs up to two feet deep in very steep, avalanche-prone terrain that has not undergone significant warming. As the day warms, the likelihood of triggering these slabs will increase along with the possibility of cornice failures. Shallow, wet loose slides will likely develop on sunlit aspects, and the spontaneous release of wet slabs could develop during the heat of the day. If skies are mostly clear throughout the day, the increase in hazard will be accelerated. Get an early start, monitor the effect that warming temperatures and sunshine have on the snowpack, and plan to either transition to cooler terrain or turn around if snow surfaces become saturated. Below 9,000 feet, the underlying snowpack beneath the recent snowfall has undergone numerous melt-freeze cycles, and significant avalanche activity is unlikely.
