Avalanche Activity
Over the last two-three weeks, we've had reports of isolated surface wind slab avalanches (D1-D2), both natural and human-triggered, in top-loaded and cross-loaded terrain between 2500-5000ft. Some wind slabs were sliding on low-angle slopes as low as 25 degrees, and appeared to be sliding on a buried surface hoar layer 10-30cm deep. Distribution of these avalanches was limited to wind loaded areas that had been protected from strong N/NW winds.
Weather
We've had 6 weeks of cold and mostly dry weather. The drought continues, but no worries because ski conditions have been great. Our last snowfall was 4-5" that fell about a week ago and freshened up the slopes. More clear and chilly weather is in store for this weekend, with continuing moderate NW winds. A strong but fast-moving front will bring snow Sunday night, probably 3-8".

Additional Information
If you get out riding, please send in an observation!
Do a rescue practice with your partners. Always carry a beacon, shovel, and probe, and KNOW HOW TO USE THEM.
Practice good risk management, which means only expose one person at a time to slopes 30 degrees and steeper, make group communication and unanimous decision making a priority, and choose your terrain wisely: eliminating unnecessary exposure and planning out your safe zones and escape routes.
