Danger Rose Tutorial

There is a level 3 or Considerable danger in the backcountry, and dangerous avalanche conditions exist. You are likely to trigger persistent slabs and wind slabs on slopes approaching or steeper than about 35 degrees, especially in drifted terrain at upper elevations. Careful snowpack evaluation, cautious route finding, and conservative decision making are crucial in the backcountry today.

CURRENT CONDITIONS

Heavy snowfall, strong winds, and rain yesterday certainly upped the anti and created dangerous avalanche conditions on many slopes.

The Tony Grove Snotel at 8400' reported a couple feet of new snow over the weekend, containing 3.5 inches of water, but only 2/10ths of an inch in the last 24 hours. There's 79 inches of total snow at the site containing 194% of average water for the date. The CSI weather station on Logan Peak reported sustained 20-25 mph southwest winds with gusts in the 60s yesterday and shifting from west to northwest overnight.... The wind sensor at the CSI weather station on Logan Peak is rimed, and it's not reading wind speeds this morning, but it's 16 degrees at 9400'.

RECENT ACTIVITY

We've received numerous reports of avalanches and sensitive or "touchy" snow conditions across the region. Details are limited from the event, but it appears two backcountry skiers were caught and carried in an avalanche in the Central Wasatch on Sunday. The two were partially buried, one sustained a broken leg, but was still able to ski out with the assistance of his companions. A large natural cycle occurred Sunday in the Provo Area Mountains, and other sizable natural and triggered avalanches have been reported from across the region......

Locally; I remote triggered a soft slab avalanche during the onset of the storm on Saturday, and fairly large naturals ran overnight Sunday night on the east side of the Wellsville Range above the town of Mendon. I did not get any observations from the backcountry yesterday...

THREAT #1

WHERE

PROBABILITY

SIZE

TREND

Over the next 24 hours.

Cold temperatures weakened the surface snow late last week, and rapid accumulations of heavy new snow and sustained west winds over the weekend have created dangerous avalanche conditions on many slopes in the area. Dangerous triggered avalanches are likely to occur. Avalanches can be triggered remotely from a distance, or worse from below!

THREAT #2

WHERE

PROBABILITY

SIZE

TREND

Over the next 24 hours.

Watch for and avoid stiffer drifted snow or potential wind slabs near ridge lines and in and around deposition prone terrain features like gullies, cliff-bands, and sub-ridges. You probably could trigger wind slab avalanches 2 to 4 feet deep on freshly drifted slopes approaching 35 degrees or steeper.
