Avalanche advisory

Wednesday, March 17, 2004,†† 7:30 am

 

Good morning, this is Evelyn Lees with the Forest Service Utah Avalanche Center with your backcountry avalanche and mountain weather advisory.Today is Wednesday, March 17, 2004, and itís 7:30 a.m.This forecast is brought to you in partnership with the Friends of the Utah Avalanche Center, supported in part by Black Diamond Equipment.

 

Current Conditions:

The seemingly unshakable high pressure has northern Utah under a dry, northwest flow this morning. Skies are clear, and temperatures have cooled into the low to mid 20ís at most elevations. The northwesterly winds are quite brisk, with hourly averages in the 20 to 35 mph range along the ridges.The highest, windy peaks have speeds over 40 mph, with gusts near 60.

 

On sunny slopes, the snow surface will be frozen rock hard this morning, but will gradually soften as the day proceeds, and eventually reach the slush stage on most steep sunny slopes and on slopes of all aspects at the mid and lower elevations.The shady upper elevation slopes have a lot of wind damage, with only the smallest stashes of soft powder remaining.

 

Avalanche Conditions:

Like most things in life, timing is everything, and that includes spring travel in the mountains. While the avalanche danger is low early in the day, it increases as the snowpack heats up and the bonds between the grains start to melt.Once the snow becomes wet and sloppy, like a slurpy, it is time to get off that steep slope.Switch to a cooler aspect, get on lower angle slopes, or head home for the day.

 

Snow conditions at the upper elevations continue the change.There are new hard wind slabs sitting on weak snow that could crack out beneath you, taking you for a ride, and some steep sunny slopes have exceptionally unconsolidated wet loose snow, especially near rocks. So whenever youíre traveling on steep slopes, evaluate the stability carefully, and go one at a time.

 

Bottom Line for the Wasatch Range, including the Salt Lake, Park City, OGDEN, AND PROVO AREA MOUNTAINS:

The avalanche danger is mostly low this morning.With day time heating, the danger of wet, loose sluffs will rise to MODERATE on steep low and mid elevation slopes of all aspects and on all steep sun exposed slopes.

Mountain Weather:

Skies will be mostly sunny today, with breezy northwesterly winds. Speeds will average 20 to 30 mph this morning, with stronger gusts, but there is a chance the winds will decrease by afternoon as they did yesterday. Temperatures will warm into the mid 40ís at 8,000í, and near 30 at 10,000í.Clear skies tonight, with lows near 30.Warmer on Thursday, with highs in the mid 30ís at 10,000í and near 50 at 8,000í. Looking into the future, the high pressure is unquestionably overstaying its welcome, with dry conditions and very warm temperatures forecast through the weekend and into early next week.
