Avalanche Information

Thursday, April 21, 2005 4 pm
Good afternoon, this is Bruce Tremper with the Forest Service Utah Avalanche Center with your backcountry avalanche and mountain weather advisory.  Today is Thursday, April 21, 2005, and its 5:00 pm. Well issue intermittent afternoon updates as conditions change until around the end of April.

Current Conditions:
The sun peeked through the clouds this afternoon as well as yesterday afternoon and made the new snow damp to wet on most slopes except for the steep, north facing slopes above about 10,000. Its kind of that springtime transition time between powder and wet sluffs. This afternoon finished off the powder and the wet sluffs start tomorrow.

Avalanche Information:
Unfortunately, I wasnt able to get out today, but people reported that the new snow was staying in place fairly well with just some localized cracking and small, soft, wind slabs cracking out on some of the steep, upper elevation ridges where the south winds blew yesterday. When the strong spring sun hit the steep south facing slopes, it made some localized damp to wet sluffs and produced rolleballs on the north facing slopes below about 9,000, but cloud cover today helped keep the wet sluffs to a minimum.

Im expecting a big warm up for the next couple days, which will certainly make some widespread damp to wet sluffing on most slopes steeper than about 35 degrees. This may also include upper elevation north facing slopes. So as usual in the spring, its a good idea to get out early and get home early and follow the aspects around as the sun moves through the sky. The idea is that you catch it as soon as the sun has softened the surface crust but get off of it before the sun make everything start to sluff.

Since we have a limited staff and limited amount of information coming in this time of year, we wont be issuing danger ratings.

Mountain Weather:
Friday should be mostly sunny with just a few scattered high clouds. Ridge top temperatures should rise to the upper 30s and get up to 50 degrees down at 8,000. Saturday should be a real cooker with high clouds and ridge top temperatures rising to the mid 40s and to 55 or 60 down at 8,000. But the powder is not quite over yet as we should get yet another snow storm starting early Sunday morning and it should continue through Monday.
