Today's Discussion

The National Weather Service Forecasts-

Today- Mostly sunny. Highs around 35. Light winds.

Tonight- Mostly clear. Lows 16 to 22. Light winds.

Tuesday- Mostly cloudy. Isolated snow showers in the afternoon. Highs around 30. Light winds.

We have seen several days of sun and calm after several days of rains to our local summits. The snowpack is quite stable at this time. Avalanche Danger is LOW today.

Keep an eye out for small point release avalanches on the sunny slopes later in the afternoon. The more it heats up the more likely this becomes. South to West facing slopes later in the say. With these cold temps in place this activity will remain limited and isolated.

Always be looking for glide cracks and areas of glide to know when instability increases to this hazard in regions. If you see glide cracks simply avoid those areas.

Currently temps are 20f at Eaglecrest and 24f at the Tram Summit. Winds are mild at 4-5mph out of the north.

Enjoy another beautiful day.
