Uintas Avalanche Advisory

Forecaster: Craig Gordon

BOTTOM LINE

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


Danger Rose Tutorial

The danger of wet avalanches will rise from LOW this morning to MODERATE during the heat of the day on steep, sun exposed slopes and human triggered avalanches will be possible.

As the upcoming storm materializes and new snow stacks up, the avalanche danger will rise accordingly.


CURRENT CONDITIONS

High clouds moved into the region late yesterday, but early this morning skies have cleared and temperatures cooled off the past few hours. Currently at 10,000’ it’s 29 degrees and down at the trailheads right around 34 degrees. Southwest winds picked up at 3:00 this morning and are averaging 30 mph along the ridges with gusts near 45 mph near the high peaks. Riding and turning conditions are a mixed bag. Down low you’ll find hard, crusty snow early this morning that’ll soften to a corn-like surface later in the day, before turning to unsupportable glop. However, a few patches of cold dry powder will still be found on high elevation, due north facing slopes.


RECENT ACTIVITY

A few wet, afternoon sluffs like this one of Hayden Peak, but in general it’s pretty quiet on the avalanche front.

THREAT #1

WHERE PROBABILITY SIZE TREND
      Over the next 24 hours.

Today’s avalanche concerns involve damp snow and the possibility of triggering wet slides during the heat of the day, especially on mid and lower elevation slopes facing the north half of the compass. I think today’s afternoon cloud cover will help temper most of the avalanche activity, but a good rule of thumb is to get off of and out from under steep, sun exposed slopes as they’re getting baked by strong afternoon sun. Also, avoid terrain traps like gullies and road cuts where debris can pile up deeply.

Another storm rolls in late this afternoon and avalanche conditions will change in the next few days as we go back into a winter-like pattern. We’ll need to readjust our avalanche radar as well. This isn’t going to be a huge storm, but as new snow stacks up be sure to stomp on road banks and small test slopes to see how they’re reacting before committing to big terrain.


THREAT #2

WHERE PROBABILITY SIZE TREND
      Over the next 24 hours.

Cornices have grown huge and may continue to break much further back than you might expect. Getting on the wrong side of a boxcar size piece of snow will definitely ruin your day. I’d give these unpredictable monsters plenty of respect and avoid walking out on one to see what’s on the other side.


MOUNTAIN WEATHER

Today we can expect increasing clouds and southerly winds ahead of a moist Pacific storm system slated to impact the region beginning this afternoon. Today’s highs reach into the mid 40’s at 8,000’ and upper 30’s at 10,000’. Snow should begin around dinner time, continuing overnight and into the morning hours Thursday. The storm winds down Thursday afternoon and I think a foot of snow is a pretty good bet. It looks like a break in the action for Friday with another system dropping into the area for the upcoming weekend.
