With 8 days of above freezing weather and rains the snowpack settled and stabilized quite a bit.

Over the last 2 days temperatures have continued to fall helping to lock the snowpack back up and greatly increasing stability.

Two mornings ago the temperature was 36f at the Mt Roberts Tram summit. Today we are at 22f. Eaglecrest had a mid mountain high yesterday of 30f and a low of 18f. Its currently 17f on top, 20f at mid mountain and 21f at the base area.

The snowpack is quite stabile right now. AVALANCHE DANGER IS LOW at this time. Natural and Human Triggered avalanches are unlikely.

Glad remains an issue. Continue to look for areas of glide and remember they are unpredictable and should be avoided.

Winds are blowing a bit this morning but there is not enough snow to transport to raise significant concern. You may find very shallow windslabs near summit and ridgeline but more so on the mainland than on Douglas. Douglas winds have been a little lighter.

Be safe out there and enjoy another beautiful day.
