December 6, 2016


    An avalanche buried two weather technicians in Sochi, story in article section.                   Net Pic

No new avalanche activity reported locally. Temperature gradient is prime for facet development. There are areas where the 16-11-12 Mfcr is 30-60 cm below the snowpack, faceting will be occurring on the crust. Something to be wary of. Cold temperatures until Wednesday, with the possibility of alpine temps remaining cold into the weekend.


    Cloudy in the morning, Monday December 5, 2016. Very light snow briefly.

    Sun tried to make an appearance mid morning.

    It did lighten up for a while.

    Cloudy in the morning.

The high lost yesterday, but has strengthened today with a strong East-Northeast flow. Arctic out break will bring sunny skies to the area . Wednesday will see some cloud move into the area in the afternoon with the next weak frontal band arriving on Thursday. Models are not in agreement on snow amounts as a low pressure off the coast develops and brings several frontal bands in a Westerly flow into the area over the weekend. There will still be some influence from the arctic high to the Northeast. Lets hope the frontal bands do not migrate South. Still early but more on that as we get closer. Dress warm today if you are venturing out. -17 in the alpine with a 25 KPH wind equates to a wind chill factor of -28. Conservative Guesstimates: 5-15 cm by Friday morning, 5-20 by Saturday morning-depends on which model is the most accurate. There is still a chance that everything could line up perfectly and we could get 40+ cm!!!

    Tuesday Morning

    Ridge appears to strengthen as the day progresses.

    Wednesday afternoon into early Thursday morning.

    Battle of the high and low.
