Thinning cloud cover combined with a drop in temps overnight have allowed the surface to refreeze at all elevations. That firm surface will lose strength as the day progresses, with temperatures at 1,000’ expected to reach into the high 40s F. Travel will become difficult as rising temperatures and sunshine will allow snowmachines and skis/boards to sink well below the surface. It will be important to get off of steep sunlit terrain (over 40 degrees) in the higher elevations and all terrain in the lower elevations as the melting occurs. Wet loose sluffs will be easy to initiate as things heat up. These avalanches will have the potential to knock you over and cause injury. It will be equally important to plan your route back to your vehicle with this heating in mind; anticipate the terrain you will need to move through and plan accordingly.
Temperatures will rise considerably today. This will aid in destabilzing cornices that have grown over the course of the entire winter. Steer clear of cornices. When travelling at or above their level, know where they connect to the underlying terrain. When travelling below make sure that you are out of the potential fall line of these massive blocks of snow.
In the past 24 hours no measurable precipitation has fallen on Turnagain Pass. Clouds were consistent during the day yesterday and have gradually dissipated overnight. Ridgetop temperatures have averaged in the high 20s F (27 F at Sunburst station). Winds there have been light averaging 9mph (max gust 25 mph) out of the East.
Today expect clearing skies and continued mild temps. Temperatures at 1,000′ will reach into the high 40s F and ridgetops should see temps into the low 30s F. Winds will remain light out of the East at 5mph. Only an occasional rain/snow shower can be expected for today.
The extended outlook is showing another day of mild and partly cloudy weather, with light rain showers possible on Friday. A quick break on Saturday will bring sunny skies before another weak low pressure brings back clouds and light rain on Sunday.
