Temperatures continue to remain quite warm. The Mt Roberts Tram summit barely touched freezing for a bit for the first time in over a week. The tram high was 38f yesterday and its currently about 33f. Eaglecrest is much the same with a mid mountain low yesterday also at just under freezing. The high was 36f. Currently its 36f at the base area, 32f at mid mountain and 30f on top.

We received about 5mm of precip along the channel at the tram with nearly double that at 11mm of precipitation at the Eaglecrest station. Along the channel where temps tend to hold slightly higher this left us about 1cm of new snow and a net gain of 0 snow after settlement. Eaglecrest was slightly colder and also received more precipitation. They picked up 7cm of new snow with a net gain of 5cm. On top look to see closer to 10cm (4\") of snow.

Winds were mild with both stations showing 8-12mph winds with gusts a little higher on Douglas.

With new snow on the ground and above freezing temperatures in place still for the most part avalanche danger remains MODERATE. Both Natural and Human Triggered avalanches are possible.

Look to see lower elevations slides of wet slab or glide releasing snows off of steeper unanchored slopes. At upper elevations be aware that you may see skier triggered wet loose and wet slab avalanches.

Conditions continue to dry out. Tonight temperatures are to fall and remain cooler for tomorrow. This should help reduce avalanche danger.

Once again watch for areas of glide and be aware that danger lingers and is very hard to predict.

Be safe out there and enjoy the new snow!!!
