Overnight temperatures dropped into the low 20ís above 9,000 feet, and to near 30 degrees at 7,000.† At the 6,000 foot level, temperatures remained above freezing but with only some high clouds last night, I expect a decent re-freeze of the snow pack at all elevations.† Winds have been from the northwest 10 mph or less below about 9,000í.† Above 9,000í winds are from the northwest in the 15 mph range with gusts over 30, and along the highest ridgelines wind speeds are 20 to 40 mph sustained, depending on location, with gusts over 50 mph.
Backcountry slopes have crusts of varying thickness and there is still some soft settled snow on protected due north aspects.† Crusts are supportable on southerly facing slopes at around seven to eight thousand feet.† If you are looking for corn you need to start early and to help you with those alpine starts we will be doing a corn hunters report on the (801) 364-1581 line at for the rest of the season. †
Yesterday there were two

The winds have limited our wet avalanche activity over the past few days, but the potential exists.† As the day heats up the danger of wet avalanches will increase.† As the snow gets wet and slushy stay off out and out from under steep sun exposed slopes.
In addition to corn slabs and the daily increase in wet slide activity, we still have some deep slab concerns.† Strong ridge-top winds are building wind drifts, but I expect fresh wind drifts to be limited to high elevation areas. †The last reported deep slab avalanche releasing on Tuesday, but the weak layers are still down there and stability tests indicate that they are still sensitive.† The most recent slides were in Mineral and Silver Forks in Big Cottonwood and Hogum in Little Cottonwood.† These slides broke 3 to 4 feet deep on north through southeast facing slopes between about 9 and 10 thousand feet. †Along with all the big avalanches we have also received reports of folks riding steep lines without incident.† This type of pattern makes avalanche decisions difficult.† Although there are many safe places to travel, there remains the possibility of triggering a very large and deadly avalanche.†
The avalanche danger is MODERATE on northwest, north and east facing slopes steeper than about 35 degrees.† On southerly facing slopes the danger is generally LOW this morning but will rise to MODERATE with daytime heating.† There is also a MODERATE danger of triggering a deep, very dangerous hard slab avalanche in steep terrain, especially in thinner snowpack areas.†
cool northwest flow will be over
