special announcement We're excited to introduce for the 2017/2018 winter the Utah Avalanche Center podcast, hosted by forecaster Drew Hardesty and produced by KUER's Benjamin Bombard. The podcast will include engaging stories, interviews, and lessons learned - all things avalanche to help keep people on top of the snow instead of buried beneath it - and easily found on ITunes, Stitcher, the UAC blog, or wherever you get your podcasts. |
current conditions Lots of heavy new snow and drifting from strong west winds overloaded widespread weak sugary snow, and dangerous avalanche conditions exist in the backcountry. The Tony Grove Snotel at 8400' reports 21°F and 48 inches of total snow containing 110% of normal SWE (Snow Water Equivalent). The site recorded 8" of new snow yesterday, with 1"SWE. 17 inches of new snow accumulated Saturday, with 3.9" SWE at the site since Friday, 12/22/17. It's 14°F at the 9700' CSI Logan Peak weather station, and the wind sensor is not reading due to ice. It is quite windy at the UDOT Hwy 89 summit weather station with 24 mph west wind and gusts of 35 mph
