How to Read Our Snow Data Above
Snowfall amounts for 12hr (overnight), 24hr, and 48hr timeframes are based on measurements taken at 5am daily. 24hr and 48hr snow totals are cumulative, so whatever fell in the last 24 is built into the 48. Between 5pm and 5am our weather data is automatically updated based on telemetry data from Northwest Weather and Avalanche Center and represents our overnight totals. The "Since 5am" snowfall amount is based on manual measurements taken periodically throughout the day.

January 17, 2017: I was skeptical about the quality of the turns when I headed out this morning, but I was pleasantly surprised to find them good. The small amount of freezing rain we have seen has mixed with an equal amount of snow and hasn’t affected the groomers negatively. Groomed runs are edgy and fast but off-piste riding is firmer and less entertaining. Now, I’m not saying it is a fabulous day out but the mountain is still riding really well on the main runs. Higher humidity mixed with the lingering temperature inversion make for frigid chairlift rides and low clouds have the visibility low as well. So be sure to bundle up. But, if you brave the weather and the forecasts, you’ll find quality corduroy with few people around to chop it up. Zero lift lines of course! In anticipation of the storm, we have limited operations with Summit Central chairs Holiday, Triple 60, and Central Express running until 4 PM. I went looking for good turns and found them at Summit Central. Don’t be afraid to come get some for yourself.
