Avalanche Information

Tuesday, April 19, 2005  6pm
Good evening, this is Bruce Tremper with the Forest Service Utah Avalanche Center with your backcountry avalanche and mountain weather advisory.  Today is Tuesday, April 19, 2005, and its 4pm.  We’ll be putting out afternoon updates every few days or as conditions change until around the end of April.  

Current Conditions: 
We’re temporarily back to winter again with much colder temperatures and snow in the mountains.  Unfortunately, it’s not much snow.  Only couple inches fell today at upper elevations and there is another burst occurring late this afternoon that may add another couple inches.  Unfortunately, the wind is also blowing hard from the southeast and it’s blowing the snow around quite a bit.  The rain-snow line is between 6,000 and 7,000 feet.  The old melt-freeze crust under the skiff of wind blown snow is quite variable and the lone backcountry report I have today said that you were punching through the crust into wet snow once in awhile.  I expect that the continued cold temperatures will freeze the crust a little thicker over the next couple days.

Avalanche Information:
There’s not much happening in the avalanche department since the colder temperatures have locked up the wet activity and there’s not enough new snow to be much of a problem.  The only caution is that the wind has created very localized shallow, soft wind slabs.  One person was able to kick off one—a measly 2-4 inches deep and not too wide.  However as the new snow piles up and if the wind keeps blowing, you might find some localized wind slabs a foot or so deep by morning, which could be more of a problem.  You will likely find them especially along the upper elevation ridges.   Since I haven’t been in the field lately and we only have limited information coming in this time of year, I won’t issue any danger ratings.

Mountain Weather:
We have a closed low pressure center moving over the top of us and taking its sweet time.  This should keep our skies cloudy with scattered, light snow showers in the mountains with perhaps 1-3 inches of snow overnight and another inch or two on Wednesday.  The rain-snow line should hover around 6,500’ and the ridge top temperatures should remain be around 20 degrees and the 8,000’ temperatures should be around 25 tonight and near freezing on Wednesday.  Ridge top winds will be variable as the low passes overhead.
