Good Morning Juneau.

Yesterday morning we started off cool and quickly warmed to our daily highs by 11:30am before cooling off for the afternoon and evening. The lows for the day came around 7pm last night before the precipitation moved in.

Yesterdays High at the Tram and Eaglecrest Mid Mountain both were 36f. The 7pm lows touched 29f at the tram and 28f at Eaglecrest.

Currently its 31f at both stations. Eaglecrest is 33f at the base and 28f on top.

We received 7mm of precipitation at the Mt Roberts Tram depositing 8cm of new snow! Eaglecrest also received about 8cm of new snow at Mid Mountain.

Winds were blowing considerably on Douglas Island with Eaglecrest blowing SE15-25 Gusting 30mph. The Tram is a little calmer showing SE8-15 gusting 20.

With a bit of new snow, an old icy bed surface, and considerable winds avalanche danger is MODERATE today. Human Triggered avalanches may be possible in windloaded locations. Use caution in areas near summit and ridgeline that are exposed to wind.

As we see light precipitation and continued warming today we may see some natural activity at lower elevations near the snow line as it climbs. These would be in the form of wet loose avalanches. Sizes would be expected to be small. But you may see snow cleaning off trees, rocks, and steep unsupported pitches causing small slides.

The forecast calls for only a little warming and light precipitation volumes. We do not see danger increasing significantly over the next 24 hours.

If we see much direct sunlight the new snow will be creating more loose avalanches in those sun exposed areas. Once again all small slides.

Be continuously aware of areas of glide and remember they remain unstable and very unpredictable. They are to be avoided.

Hope you get out and taste some snowflakes.
