Good Morning.This is Ethan Greene with the Forest Service Utah Avalanche Center with your backcountry avalanche and mountain weather advisory.Today is Monday, January 27, 2003, and itís 7:30 in the morning.This advisory is brought to you by our partner, the Friends of the Utah Avalanche Center, generously supported by Black Diamond Equipment.

 

Current Conditions:

Get out your grass skirt and guava juice, because last night it was down right tropical in the mountains of northern Utah.Temperatures warmed all day yesterday and they kept rising through the night.This morning temperatures are in the mid to upper 30ís at 8,000í and near 30 degrees at 10,000í.In some areas of the Ogden and Provo Area Mountains temperatures at 6am were near 40 degrees at 7,500í.The winds have been from the west and southwest overnight in the 15 mph range.Along the highest ridgelines wind speeds are in the 25 mph range with some gusts over 40 mph.

 

The snow surface is a mix of faceted snow and crusts.Yesterday I received reports of good dust-on-crust turning conditions in upper elevation areas, and nice loud powder turning in areas sheltered from the wind and sun.

 

Avalanche Conditions:

Today is going to be an interesting day in the backcountry.The backcountry snowpack is generally thin and weak.The new snow that fell late last week has also faceted leaving the snow surface a mix of surface hoar, near-surface facets, and a variety of wind and sun crusts.Today the wind is going to blow and itís going to rain! Temperatures should be cooling during the day and I donít expect much precipitation until the afternoon.However, you may want to pack your slicker incase the precipitation starts in earnest before the colder air arrives.

 

With tropical temperatures and rain in January, we are most certainly in the middle of an odd weather event.If my numerical crystal ball is correct, our avalanche conditions will not change significantly until after sunset.However, today the most important thing to remember is that odd weather events produce odd avalanches.

 

Bottom Line (SLC, Park City, Ogden and Logan Area Mountains):

Today the avalanche danger is probably LOW this morning, but will be increasing during the day.With strong winds and rain turning to snow the avalanche danger may rise to MODERATE this afternoon and could continue to rise overnight.††

Mountain Weather:

Wind speeds and cloud cover will increase today ahead of a fast moving Pacific Storm.Temperatures are quite warm this morning, but I expect most areas will gradually cool during the day.High temperatures will be in the low 40ís at 8,000í and low 30ís at 10,000í.Southwest winds will increase in to the 25 mph range, but along the highest ridgelines we could see sustained speeds in the 30 to 40 mph range this afternoon.Precipitation will spread south during the day.The rain/snow line could be as high as 9,000í today, but should drop to 7,000í overnight.I expect an inch or two of snow could accumulate by sundown and an additional 4 to 8 inches by Tuesday morning.

 

General Information:

Weather permitting, Wasatch Powderbird Guides will be flying in Lambís Canyon and the American Fork drainage today.
