February 4, 2017


    An avalanche in Babakhshan, Afghanistan has killed 10 people, story in article section.   Net Pic

    Locally no new avalanches observed, surface sluffing to Sz 1 on steep lee terrain.


    Started to snow at 08:15 Hours Friday February 3, 2017.

    On an exceptional year you can ski up onto this rock.

    Snowing in the valley Saturday morning.

    Sun was visible at times through the thin cloud layer.

    Snow eased in the afternoon but picked up again in the evening.

    Big Picture Friday. How will the 2 lows meld?

    There was some fine skiing off piste and on.

    Overall another great day in the mountains.

    As of 07:00 hrs this am we have obscured skies, limited visibility and it is snowing 1 cm per hour.


A cold upper level low will bring light snow to the area today in a strong Southwest flow. The FL will remain below surface and we should see an increase in the snowfall by this evening. An upper trough will bring some light snow to the area Sunday morning but the Arctic high strengthens on Sunday pushing the low enough to bring some unsettled weather by Sunday afternoon. Cool unsettled weather will prevail early next week with the occasional flurry. As of now a warm front will move onto the coast Wednesday night with heavy snowfall into Thursday but with a rising FL. Looking like Thursday will be a storm day.
Guesstimates: 25-35 cm by Sunday morning, 2-6 cm by Monday morning?

    GOES IR image from this am.

    Looking like some decent precip amounts for today.

    Overcast and snow into Sunday.

    Unsettled conditions likely by Sunday afternoon.

    A mix of sun and cloud with cool weather for Monday.


   Freestyle competition on Blackcomb Friday.

    Snowy but a great venue.

    By noon the snow was accumulating.

    Steeps were skiing well yesterday.

    Smooth conditions for most of the alpine terrain.

   Dry light snow to the valley.
