Avalanche Advisory
Advisory: Logan Area Mountains Issued by Toby Weed for Monday - March 17, 2014 - 6:54am
bottom line

Most slopes are stable, but heightened avalanche conditions exist and may develop further in some areas today. There is a MODERATE or level 2 danger on drifted slopes at upper elevations, with shallow wind slab avalanches and cornice falls possible. Wet avalanches will become increasingly possible in steep mid and lower elevation terrain, and rain or periods of sun with greenhousing could cause the danger to increase and become more widespread. Evaluate the snow and terrain carefully.




special announcement

Sale on all remaining discount lift tickets donated to the Utah Avalanche Center from Beaver Mountain, Wolf Mountain, Sundance, and Brian Head: The few remaining tickets are being blown out with all proceeds used to pay for avalanche advisories and education. Go here to get your tickets.

Snow coverage and conditions are stellar at Beaver Mountain this spring. 3-12-2014

current conditions

The Tony Grove Snotel at 8400' reports a balmy 39 degrees, 110 inches of total snow, and 134% of average water content for the date. It's 33 degrees at the 9700' CSI Logan Peak weather station, which recorded steady southwest winds overnight, with average wind speeds around 30 mph, and gusts in the fifties. We found and observers report safe, stable snow, and very nice shallow powder, smooth dust-on-crust, and even nice spring corn riding conditions across the Logan Zone over the weekend.


recent activity

It's been a couple weeks since any avalanches stepping into old snow occurred in the Logan Zone. Shallow wind slabs and cornice falls are fairly frequent during and just after the spring storms, and easily predicted loose wet avalanches have been common with solar heating and seasonal warmth affecting fresh snow.

description

Wind slab avalanches involving drifted fresh snow up to about a foot deep are possible in wind-exposed upper elevation terrain. These should be of the manageable variety for experienced travelers, but a few might be stiff enough to allow you to get out on the slab before it fails.

  • Watch for and avoid drifted snow in steep lee terrain and in and around terrain features like gully walls, outcroppings, or under cliffs. Although avalanches are generally unlikely, triggered avalanches are still possible, especially in extreme or "Big Mountain" terrain.
  • Avoid and stay out from under large and overhanging cornices along major ridge-lines, which are likely to break further back than you expect and could trigger avalanches on slopes below. These will sag and buckle as they warm up, and could naturally fail during the heat of the day
  • The danger is LOW in most terrain this morning, but we still need to employ good situational awareness and continue to practice safe travel protocols in the backcountry.

Expect mild temperatures today, and mountain weather stations report a poor overnight refreeze. Wet avalanches are generally unlikely but possible where poor snow structure is softened by melt. Mild temperatures are forecast to gradually cool throughout the day, with overnight temperatures dropping into the teens, which will help the situation, but periods of sun and greenhousing this afternoon or rain on the snow up into the mid elevations could cause an increasing danger of wet avalanches in some steep terrain.

weather

A fast moving storm will push a strong cold front through the region today. Snow is likely today in the mountains, with mild temperatures and very strong westerly winds. Expect 1 to 2 inches of accumulation, gradually dropping temperatures and intensifying west winds, with 50 mph average wind speeds and gusts near 80 mph possible this afternoon. Snow showers should diminish, temperatures will drop to around 15 degrees overnight, and northwest winds will continue to be fairly strong. It'll be partly sunny tomorrow, with 8500' high temperatures around 24 degrees and moderate west winds. A dry cold front will move through the region on Thursday, and a return to the more mild westerly flow is expected for the end of the week.
