TONIGHT...CLEAR. LOWS 23 TO 31?.EXCEPT AROUND 20 IN WIND SHELTERED LOCATIONS. NORTHEAST WIND 10 MPH.

SATURDAY...PARTLY CLOUDY. HIGHS AROUND 51. NORTHEAST WIND 5 MPH.

Yesterday at the tram there was only a trace of precip. Temperatures varied between -2 and 2 degrees C throughout the day. Winds were light at around 10 kts.

For today it looks like we have some clear skies. This means that through the day avalanche activity will become more prevalent. As the sun heats up the snow pack we will probably see some wet slides around the area, especially for slopes above the flume. Slides will more than likely be small in size, however, if the temperature gets up towards 50 F there is enough incoming solar radiation to release a potentially large wet slide.

Today would be a good day to be aware of where you are walking in the afternoon.
If possible limit exposure to avalanche runout areas to the morning. Remember this is not a backcountry forecast. If you are recreating make sure you do your tests!

Tip:

Diurnal Temperature Change

For loose wet avalanches to occur we either need rain or warming. Temperatures above 50 F are a sign to pay attention to. This radiational warming can penetrate deep into the snowpack and potentially cause a large avalanche. If the snowpack then cools in the evening the resulting bonds will become stronger. The more nights that are cool after the warm days, the stronger the snowpack becomes.
