A substantial storm is expected today, with high SW-NW winds and up to 25mm of precipitation. This will bump hazard up to HIGH tomorrow in the alpine, but be aware that it could get there later today.
Summary
Weather Forecast
A Pacific frontal system will bring moderate precipitation and strong winds to the area today. Winds will shift from SW to NW throughout the day, potentially resulting in reverse loading of snow onto south aspects. Expect thick cloud and mild temperatures. Tomorrow should be a nicer day, drier, maybe even some sun.
Snowpack Summary
Variable Conditions. In the alpine, SSL and HSL from last weeks storm and wind event overly crusts on solar aspects and facets or surface hoar on north aspects. The SH (from April 4) is best preserved above 2400m, and is reactive to skier triggering. Below treeline, the snowpack has become isothermal, frozen in the mornings, mush by afternoon.
Avalanche Summary
A few isolated avalanches were noted yesterday, and reports of "whumping" by skiers, mostly in the alpine. Glide cracks and cornices are growing larger, and are failing unpredictably. Three days ago, a size 3.0 natural slab avalanche in Youngs Peak Basin and a skier remotely triggered size 2.5 - 3 off of Youngs Peak Headwall.
Confidence
Timing, track, or intensity of incoming weather system is uncertain on Wednesday
