Salt Lake Avalanche Advisory

Forecaster: Evelyn Lees

BOTTOM LINE

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


Danger Rose Tutorial

The snow in the Wasatch mountains is generally stable and the avalanche danger is Low. Tonight, strong winds could form a few shallow, sensitive wind drifts in the mid and high elevation terrain, creating pockets of Moderate danger.


CURRENT CONDITIONS

Scattered snow showers over the mountains produced a trace of snow at most locations, with up to 2 inches of snow in the Cottonwoods. Unfortunately, looking at the radar loops, the back edge is already into the valley, and the last of the mountain snow showers will be tapering off by around 8 am. Temperatures are currently in the mid 20's to low 30's, and winds are from the northwest, in the 5 to 15 mph range, with a few of the highest peaks gusting into the 30's.

Today's dusting of snow will be landing on a variety of supportable to breakable crusts, and a few patches of soft, friendly recrystallized powder. The old snow changes rapidly over short distances, with the common denominator it's shallow depth – 1 to 2' on the shady slopes. Somehow, it's still decently supportable, and if you can dodge the rocks, there are a few turns to be had. Start and finish your tours or snowshoeing at the higher elevations to stay on snow.


RECENT ACTIVITY

No avalanche activity has been reported from the backcountry or the resorts for the past week.


THREAT #1

WHERE PROBABILITY SIZE TREND
      Over the next 24 hours.

The increasing winds forecast for late this afternoon and tonight could add a little bit of interest to the avalanche scene. With widespread weak surface snow and patches of slick crusts, any drifts that form could be quite sensitive and reactive to a person. While these drifts will be quite shallow and small due to a lack of snow available for transport, they might be just enough to knock you off your feet if you're surprised in very steep terrain. I'd expect decent bonding to any of the rough melt freeze crusts.


MOUNTAIN WEATHER

The small disturbance that crossed the Wasatch early this morning is rapidly heading to Colorado. Behind this, the mountains will have partly cloudy skies today, with temperatures in the low 30's at 8,000' and the low 20's at 10,000'. Winds will be from the northwest, in the 10 to 20 mph range, with gusts in the 30's. Winds will increase tonight, with 20 to 30 mph averages, and gusts in the 40's to 60's. Then, once again, high pressure will dominate our weather as a ridge builds into the area. As the ridge strengthens early next week, very warm temperatures will return to the mountains for several days. The only storms in sight are far out in computer never-never land.
