Snowpack Summary
The entire forecast region has been basking in the sun and enjoying unusually warm temps for the past 28hrs. The region's hot spot today was Mud Lake with 6 degrees. The valley bottom snowpack is now isothermal in most areas, up to 2200m. The "winter" snowpack does not return until treeline where there is a moist surface layer sitting on top of dry facets up to 2300m. Daytime highs at treeline hit 3 degrees today with overnight lows of +1. The alpine snowpack is more variable. The effects of the sun and heat are more pronounced on south aspects, but even the north aspects have seen some heat. There was intense transport at the upper elevations. Cornices are soaking up the warm temps and becoming a potential problem.
