Provo Avalanche Advisory

Forecaster: Evelyn Lees

SPECIAL ANNOUNCEMENT

Don't miss Snowbird's Avalanche Rescue Awareness Day today from 11 till 2 at Entry 4 in Little Cottonwood Canyon. You can see the top avalanche rescue dogs in the country, practice with your beacons, learn shoveling techniques and watch helicopter search demonstrations.


BOTTOM LINE

Danger by aspect and elevation on slopes approaching 35° or steeper.
(click HERE for tomorrow's danger rating)


Danger Rose Tutorial

There is a MODERATE danger of triggering an old, hard wind slab on slopes of about 35 degrees or steeper with recent deposits of wind drifted snow, especially above about 9,000’. There is also a MODERATE danger of wet sluffs on steep, sunny slopes and on all low elevation slopes as the snow heats up with daytime warming.


CURRENT CONDITIONS

Under clear skies, it is another stunning spring-like morning in the mountains. Temperatures are in the teens in the valley bottoms, warm into the twenties at the mid elevations, before cooling back into the teens along the high ridges. The southwesterly winds are light, generally less than 10 mph, with only the Ogden ridgeline and a few other exposed peaks blowing in the 15 to 20 mph range.

Turning, riding and snowshoeing conditions are excellent in the sparkling recrystallized snow and surface hoar on wind sheltered, shady slopes. The sunny south through west facing slopes have breakable crusts this morning, which will soften rapidly as the sun hits, and upper elevation ridge lines and open bowls have wind damage, with the hard wind hammered drifts especially widespread on northwesterly facing slopes.


RECENT ACTIVITY

There was only one reported slide from the backcountry yesterday - cornice kicking on Bountiful Peak triggered a wind slab, 1-3' deep by 150' wide on a ENE facing slope at 9,200'. Explosive work at the resorts in the Ogden, Park City and Salt Lake mountains released a variety of small to medium sized slides, both pencil hard wind slabs and new snow soft slabs.


THREAT #1

WHERE PROBABILITY SIZE TREND
      Over the next 24 hours.

There are still a few places out there where a person could trigger an old soft or hard wind drift – most likely in very steep, upper elevation terrain. The hard drifts aren’t the type that respond easily to ski cuts, instead they’re more likely to be stubborn and break out above you. Also, many of these hard drifts are so slick that a slip could result in a slide for life down some chute and even a short ride might slam you into rocks or send you off a cliff. It’s still worth digging around and keeping track of the weak layers in the shallow snow pack areas, as this recent profile shows.


THREAT #2

WHERE PROBABILITY SIZE TREND
      Over the next 9 hours.

Once again, as the day heats up, it will become easy to trigger wet loose sluffs on steep sunny slopes. If there is just the right amount of thin cloud cover this afternoon, the snow on the lower elevation shady slopes may also get in on the action, with wet loose sluffs possible.


MOUNTAIN WEATHER

The high pressure over the intermountain west will weaken slightly today ahead of a very minor weather disturbance. Increasing high thin clouds today, possibly becoming overcast late this afternoon. Temperatures will warm into the mid to upper 30s at 8,000’. The winds should become more northwesterly, increasing slightly this afternoon, gusting into the mid 30s along the exposed ridges. Mostly cloudy skies tonight, with a chance for a few snow flurries, though little accumulation is expected. Then warm and dry through mid week, with the next chance for snow around Friday.
