Temperatures rose to near the point of freezing yesterday at the Mt Roberts Tram Summit during our beautiful sunny day. On some aspects I am sure the sun took a little affect.

With these near freezing temperatures our snowpack has continued to settle and consolidate quite a bit over the last week.

Winds remained light to moderate over the last few days and we have not seen much in the way of recent windloading over the last 48 hours yet there was a fair amount of windloading last week during our period of new snow accumulation.

We had several days with winds ranging from 30-50mph during periods of snow. We have had 4 significant periods of new snow over the last 9 days with over 2' of new snow overall.

With this much new snow over the last week be sure to analyze the layering and snowpack in the areas you choose to ride!

With less than .3\" precipitation in the forecast for the next 24 hours and light winds avalanche danger is low at this time. Natural avalanches are not likely. Yet be aware that with significant deposits of new snow over the last week and wind loading you may still be able to find pockets of weakness in the backcountry that could be human triggered.

Although the snow is good right now be sure to use safe riding practices. One at a time, always riding with partners, and practicing good companion rescue techniques always carrying your avalanche transceiver, probe and shovel.

Tip:

Sympathetic Trigger:

When an avalanche descends, especially in very unstable conditions, it can trigger avalanches on other nearby slopes. Don?t confuse sympathetic trigger with related terms of ?remote? trigger, meaning an avalanche triggered by a person some distance away or ?stepping down? where a smaller avalanche breaks down into a deeper weak layer. Sympathetic triggers usually mean that the snowpack is especially unstable and you can trigger other avalanches easily.
