TODAY ... PARTLY CLOUDY. HIGHS AROUND 44. NORTHEAST WIND 5 MPH BECOMING SOUTHWEST TO 10 MPH IN THE AFTERNOON.

TONIGHT ... INCREASING CLOUDS. LOWS AROUND 30. SOUTHEAST WIND TO 10 MPH.

TUESDAY ... MOSTLY CLOUDY. HIGHS AROUND 40. LIGHT AND VARIABLE WINDS.

Yesterday was another day with no precip. Temps stayed above freezing for the last 24hrs at the Tram and the same with Mt Juneau once it warmed up yesterday morning. This has helped allow for another 2cm of settlement at the Tram.

The main problem today will still be small wet slides since we are not getting diurnal freezing anymore. Breaks in the clouds, and a changing of the winds may allow for significant warming.

The avalanche danger today is MODERATE: Natural avalanches unlikely; human-triggered avalanches possible. Small avalanches in specific areas; or large avalanches in isolated areas. Use caution in or under steeper terrain and in avalanche zones.

Backcountry travel should be done with caution and remember that avalanches on the mid-February weak layer would be large and destructive. Human triggering is still possible in some areas, so choose well supported terrain and consider the consequences of an avalanche before committing to a route.

Tip:

OUR PERSISTENT WEAK LAYER

We keep talking about these buried facets we have above the solid melt freeze crust, but if you aren't seeing them then it is hard to understand our concern.

They are distributed throughout our area and very spatially variable. This is a link to a video by local forecasters Mike Janes and Ron Simenhois - it is a great visible example of the propagation of this layer across a very large block.
