Avalanche advisory

Wednesday, April 07, 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, April 07, 2004, and its 7:30 a.m. This forecast is brought to you in partnership with the Friends of the Utah Avalanche Center, supported in part by the Uinta Brewing Company.

 

Current Conditions:

Eternal spring continues in the Wasatch, with more warm weather and thundershowers in the forecast. Overnight, skies have been mostly cloudy, and temperatures are near freezing at the 9 to 11,000 elevations, and in the mid to upper 30s at 7 to 8,000. Winds are light and variable, generally less than 5 mph. Precipitation has been uneven in the past 24 hours, with most mountains stations reporting zero to a trace of rain. A few stations in the Ogden and Provo area mountains received up to an inch of rain and/or 2 of snow. Even with the overnight clouds, I expect the well consolidated snow pack to be firm this morning out of the heavily rain affected areas. There is great spring corn snow on most slopes, with the shadier slopes have the smoothest snow surface. The other usual springtime concerns exist, including slips on steep, icy slopes, emerging rocks and stumps and punchy shallow snowpack areas.

 

Avalanche Conditions:

The goal with spring travel is to avoid being on a steep slope when the snow becomes wet and sloppy. There are three main tools at your disposal to accomplish this first, early starts and early finishes, second, changing aspect and elevation to find firmer snow, and third, watching your slope angle. If you do find yourself in an area where the snow is soggy, travel on lower angle slopes and avoid terrain traps such as steep walled gullies. With the light flow aloft, todays thunderstorms could be slow moving, producing heavy rain in a few isolated spots. Again, in these areas, get off of and out from under steep slopes.

 

Bottom Line for the Salt Lake, Park CITY, AND Provo AREA MOUNTAINS:

There is generally a LOW avalanche danger this morning that will rise to moderate on steep slopes with day time heating, or in any area receiving a prolonged heavy rain shower.

 

OGDEN AREA MOUNTAINS:

The avalanche danger is moderate this morning on steep slopes, especially in areas that received heavy rain or wet snow overnight. The danger may rise to CONSIDERABLE with daytime heating or in any area receiving additional heavy rain.

Mountain Weather:

A moist and unstable air mass will remain over northern Utah today. Clouds and rain showers should decrease this morning, with partial clearing, and then increase again this afternoon. Thunderstorm activity, with lightning and isolated areas of heavy rain or snow, is possible this afternoon, with the rain/snow line near 9000. Winds will be light and variable today, less than 10 mph. High temperatures will be in the low 30s at 10,000 and in the low 50s at 8,000. Skies will be partly cloudy tonight, with low temperatures near freezing. Thursday will be partly cloudy, and cooler, with 8000 highs in the mid 40s, and a slight chance for thunderstorms. A weak cold front is expected late Thursday night which could bring light snow on Friday.
