It has been above freezing for 4 days straight at tram summit elevations. It has been above freezing for 3 days at Eaglecrest summit elevations.

We are loosing the glue that bonds the snowpack together.

We are starting to see more free moisture in the snowpack which eats at the current bonds in place.

The snowpack also tends to settle rapidly at these above freezing temperatures which also places additional stress on it.

We are starting to see a lot of spots of dirt and rock showing up on the hillside. This adds to the thermal stress in the pack by absorbing the heat from the sun.

Steep areas around rocks and trees continue to releive themselves. Areas with fewer anchors may becoming more suspect especially at lower elevations.

Be aware on steep open faces and when sking above others. Right now durnig it is easy to get a little snow moving and it can pick up quite a bit of mass and momentum.

Slide sizes are not expected to be large. But the longer this above freezing temperature persists the greater the danger for deeper weak layers to become reactive.
