Avalanche Advisory
Advisory: Logan Area Mountains Issued by Toby Weed for Tuesday - April 7, 2015 - 8:22pm
bottom line

New snow will create heightened avalanche conditions at upper elevations , with storm snow and shallow wind slab avalanches becoming possible as fresh snow piles up in the mountains.

  • Evaluate the snow and terrain carefully.

current conditions

We're moving into a generally more predictable spring pattern, and backcountry avalanches will become more likely during the heat of the day. An early start and departure this time of year can mitigate much of the wet avalanche worry, but a poor overnight refreeze will lead to earlier softening of the surface melt-freeze crust. The Tony Grove Snotel reported around 18 inches of dense new snow with the Monday/Tuesday storm, containing close to 3 inches of water, but high angle sun and warmth in the last few days turned the powder to mush, even at upper elevations. There's now 60 inches of total snow containing 80% of average water for the date, and it's currently 44 degrees at the 8400' site. It's 29 degrees at the UDOT Hwy 89 Summit weather station, with fairly light north wind this morning after moderate westerly winds yesterday evening.
recent activity

Observers report triggering a few manageable loose wet sluffs yesterday in steep upper elevation terrain, otherwise no significant avalanches were reported involving this week's new snow.
