Avalanche Advisory
Advisory: Salt Lake Area Mountains Issued by Drew Hardesty for Tuesday - March 25, 2014 - 5:43am
bottom line

We have a mostly LOW danger in the backcountry this morning that will rise to MODERATE with today's skyrocketing temps and light wind. Cornices and glide slab potential should be other concerns for mountain travel today. It'll be the warmest day yet - be off of and out from underneath the steep sun-drenched slopes by midday, if not earlier.




special announcement

This Thursday, Mar 27th, Liam Fitzgerald will be the final speaker at the Utah Adventure Journal series, talking about avalanche control in Little Cottonwood Canyon and the avalanche control program in the early days of Snowbird. Liam was the first snow safety director at Snowbird and has been an avalanche professional in Little Cottonwood ever since. Liam will be sharing stories and lessons learned from avalanche assessment and control over 45 years. There is a suggested small donation to the Utah Avalanche Center which includes a raffle for great donated gear and happy hour food and drink specials. 6pm, Wildflower Lounge, 21+

Thanks for all the love during last Thursday's Love Utah Give Utah Campaign. 97 of you came forward with $4,145 which will help plug some holes in our advisory and education programs next season plus make some website improvements over the summer. Thanks for the notes and best wishes -

SALE! on all remaining discount lift tickets donated to the Utah Avalanche Center from Snowbasin, the Canyons, Beaver 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.

current conditions

Skies are clear. Mountain temps are in the mid to upper 20s with many temperatures along the thermal belt (neither high nor low elevation) in the mid 30s. Westerly winds are all but a whisper.

As we've heard before, timing is everything. Yesterday's corn harvest went off by 10am on east, 11am on south, and a bit later on west. Too early and it's a visit to the dental office (as your fillings have rattled out); too late and you're punching through the unsupportable glop - at best. Advancing temps and light wind will have the game on a touch earlier than yesterday. One can still find soft settled powder in the high northerly terrain.

description

The snowpack is generally stable as long as you're off of and out from underneath the steep sun-drenched slopes before they become unsupportable and punchy. With light wind and temps skyrocketing into the 50s+ today, it'll be key to start early and finish early - or just move on to cooler aspects ahead of the sun or avoid it altogether (by heading to the northerlies). Though, with the warmest temps yet, perhaps even the mid-elevation northerlies will get damp for the first time - resulting in rollerballing and sluffing with human provocation. Other notes -

  • Growing and yawning cornices may buckle under their own (and your) weight with direct sun and warming temps
  • Glide avalanches - poorly understood but correlate to some degree with very warm temps and percolating melt water. I'd probably avoid Stairs Gulch and Broads Fork of Big Cottonwood Canyon...as well as other areas notorious for glide cracks (Raymond Slabs in Porter Fork, areas of Mill B South, etc).

weather

We'll have clear skies with some high thin clouds streaming through today. Temps will skyrocket to near 50 at 8000' and near 40 at 10,000'. Light winds will back to to the southwest and increase in the afternoon, and will reach 40mph overnight ahead of tomorrow's morning's weakening cold front. Looks a bit splittier than it did yesterday. Both winds and temps drop tomorrow with snowfall accumulations in this two-act storm adding up to perhaps 6-10" by early Friday. Thursday's 2nd piece of the storm looks a bit windier from the west and northwest, ushering in cooler temps as well. The weekend looks partly to mostly cloudy with the next storm slated for April Fool's. Really.
