Danger Rose Tutorial
|
Expect a rising level 2 or Moderate avalanche danger in the backcountry today, with strong west winds and periods of heavy snow.. Heightened avalanche conditions exist and will likely become more widespread on drifted upper and mid-elevation slopes. You might trigger wind slab avalanches on slopes steeper than about 35 degrees. Evaluate the snow and terrain carefully, especially in areas with drifted snow... |

CURRENT CONDITIONS |
|
You'll find full-on weather in the mountains today, with increasingly strong west winds and periods of heavy snowfall.... We're finding fine powder riding conditions in the Bear River Range, with good snow coverage for this time of year, especially up high. The Tony Grove Snotel reports another 3 inches of snow with 3/10ths of an inch of water in the last 24 hours. There's 57 inches of total snow at the site, containing 177% of average water for the date. The Campbell Scientific Logan Peak weather station at 9700' is reporting 17 degrees and increasing west-southwest winds this morning, with almost 30 mph average windspeeds and a recent 53 mph gust. |

Strong west winds and periods of heavy snowfall will rapidly build wind slabs in lee terrain today. Freshly formed wind slabs, 1-2 feet deep, could be sensitive to human triggering. Be on the lookout for building wind deposits in exposed upper elevation terrain and in and around terrain features like gullies, sub-ridges, scoops, and cliff bands. Cracking and collapsing are bad signs, indicating instability. Avoid steep drifted slopes with trees or other terrain traps below. |

The National Weather Service in Salt Lake City issued a Winter Weather Advisory for the mountains of Northern Utah. Expect strong westerly wind and periods of heavy snowfall today, with 6 to 12 inches of accumulation possible. Storminess should tapper to showers tonight. Another wave of moist Pacific weather will bring additional snow starting around Saturday afternoon. A high pressure system will develop for early next week.... |
