AVALANCHE ADVISORY

Friday, March 21, 2008 7:30 am
Good morning, this is Brett Kobernik with the Forest Service Utah Avalanche Center with your backcountry avalanche and mountain weather advisory. Today is Friday, March 21, 2008 and its about 7:30 am.

 

Current Conditions:

Its been a great winter to be in the Wasatch with an abundance of snow and mostly manageable avalanche conditions. Yet another refresher treated us to around 6 inches of new snow on Thursday with the Logan area picking up a bit more. Temperatures warmed quickly as the storm passed and moderate westerly winds did move the snow during the storm a little bit especially along the highest ridges. Moderate winds continued through mid day. A small disturbance this morning produced some scattered snow flurries in the northern portion of the state.

 

Snow and Avalanche Discussion:

We had numerous types of avalanche activity on Thursday in the form of natural loose, natural slab, human triggered loose, human triggered slab, and wet slide activity following the clearing. Most of this activity was fairly shallow and the slabs generally less then 30 feet wide but there were a couple along the highest ridges that cracked out 100 feet wide or so. Some of the human triggered activity did run a fair distance. The wet activity probably posed the greatest threat producing some sizeable debris piles that would grind you up pretty good if you were caught.

 

All of the activity from Thursday should be much less pronounced today but well want to watch for similar things. You may be able to still initiate sluffing and small soft slabs on the steep northerly facing slopes that have powder remaining. Wet activity will probably be less pronounced as well but dont let your guard down and constantly monitor how damp the snow becomes. Consider where your route may put you later in the day during the most intense heating. Savvy folks stick to shaded high north aspects as things heat up and avoid gullies and terrain traps.

 

Bottom Line for the Salt Lake, Park City, Ogden and Provo area mountains:

We will have a pockety MODERATE avalanche danger today from avalanches within the new snow. You may still initiate sluffing and small soft slabs in the high north terrain. The avalanche danger will rise to MODERATE on the southerly aspects as well as north at lower elevations with daytime heating.

Mountain Weather:

Moisture in the mid portion of the atmosphere pushing up against the mountains will form some clouds and the slim chance for isolated flurries this morning with clearing expected later. Westerly winds will blow strongest this morning then slow a bit afternoon. Well see gusts near 40 at the most exposed locations and gusts to around 20 along the mid elevation ridges slowing as the day goes on. Temperatures will reach into the mid to upper 30s at 8000 feet and around 30 at the higher locations. Dry conditions with warming will occur over the next few days.
