Current Conditions: ††
The series of small storms from last Friday through Monday added some much needed depth to our current snowpack.Temperatures have remained cold and wind speeds have calmed down after Mondays blast.Currently skies are cloudy over the mountains.Temperatures at 8,000 feet are near 30 and in the low 20s at 10,000 feet.Ridge top winds are from the northwest at 20 miles per hour with gusts to 50 at the highest locations.

Avalanche Discussion:
Mondays wind slab avalanches are now a thing of the past.Although, if you dig down you will continue to find shears above last Fridays frozen crust.These shears are down 12 to 24 inches and are somewhat stubborn and not real clean either.(Snow Profile)You may also find some minor cracking higher in the snowpack on graupel that fell on Monday. I donít think that either of these shears present a problem right now.

Wind and temperature changes over the next week will dictate what type of avalanche problems we may encounter if any.The first thing that comes to mind is there is enough loose snow on the surface that could get blown into sensitive drifts with the forecasted winds today.The next thing to keep in mind is problems with wet avalanches.Temperatures should warm a bit over the weekend, so this danger could increase on steep southeast through southwest facing slopes especially on slopes that had snow prior to our last storm.

A bigger danger right now is the possibility of falling on rocks just under the snow surface.Keep in mind that a lot of areas have a very shallow, unconsolidated snowpack.Have patience.You donít want to end your winter season due to injuries before it even really gets started.

Mountain Weather:
A high pressure ridge is making its way over Utah.Until it settles in directly over us during the weekend, weíll see a northerly flow bring enough moisture through to produce some cloudiness and even a snow flurry or two in the Uintas.Once the ridge is in place, its unwelcome presence may last through next week.

For Thursday weíll see a few clouds moving through in the morning then clearing late afternoon.Temperatures at 8,000 feet will be in the mid 30s and upper 20s at 10,000 feet.Ridge top winds will be from the N at 10 to 20 miles per hour with gusts into the 40s & 50s at the more exposed locations.Friday will be mostly clear with slightly warmer temperatures.Ridgetop winds should remain from the north at 10 to 20 mph.

Temperatures should warm up a bit more over the weekend and stay there into next week.

We will update this advisory as conditions warrant.Stay tuned and thanks for calling.††
