Forecast for the Logan Area Mountains

Toby Weed
Issued by Toby Weed for
Saturday, April 6, 2013

Cooling is solidifying the saturated snow and conditions are becoming mostly stable. The danger is LOW on most slopes in the backcountry, but pockets with heightened avalanche conditions and a MODERATE (or level 2) danger of wet avalanches remain in some steep rocky areas. Evaluate the snow and terrain carefully, avoid steep terrain with melt-softened snow in the heat of the day, and continue to follow safe travel protocols...

Weather and Snow

The Tony Grove Snotel at 8400' reports around 5" inches of new snow, containing 6/10ths of an inch of water, and temperatures dropped below freezing early this morning for the first time in well over a week.... it's 31 degrees. With 48"of total snow, the station now contains 54% of average water for the date. The CSI Logan Peak weather station at 9700' reports dropping temperatures this morning; currently it's 26 degrees with southwest winds averaging in the mid teens. Gradual cooling and cloud cover yesterday slowed the down the meltdown, and there is a few inches of heavy new snow at upper elevations.

Recent Avalanches

No new avalanches were reported recently in the Logan Area.....

But, a very large natural heat related persistent slab avalanche occurred in the midday heat on Wednesday in the Western Uintas. Graig Gordon and Ted Scoggins of the Utah Avalanche Center visited the site Thursday and report something like a 3/4-mile wide and four-foot deep monster....

Here's a link to our updated Avalanche List.

Avalanche Problem #1
Wet Snow
Type
Location
Likelihood
Size
Description

Gradual cooling and cloud cover this weekend will pause the meltdown and help to solidify the soft and saturated snow.. Even though the danger is dropping with the temperatures, wet avalanches remain possible after an extended warm spell. Pockets of heightened avalanche conditions exist in steep rocky terrain. With midday temperatures forecast close to 40 degrees at upper elevations again, an early departure from the mountains will be a good call. You should continue to avoid steep terrain where you punch into saturated snow.

Avalanche Problem #2
Wind Drifted Snow
Type
Location
Likelihood
Size
Description

New snow sluffs and fresh soft wind slabs are possible today at upper elevations, but these should be small and generally manageable. Watch for terrain traps like trees or gullies below you.... Wind slabs are likely to develop with windy and prefrontal conditions tomorrow...

Additional Information

A moist westerly flow will bring periods of rain to the valleys and snow to upper elevations through the weekend, and a cold Pacific storm will affect the region early next week. Expect snow showers, with an inch or two of accumulation possible, moderate west winds, and high temperatures at 9000' pushing 40 degrees today. Snow showers and moderate westerly winds will continue overnight and mountain temperatures will hover around freezing. Snow will develop tomorrow along with intensifying southwest winds. 4 to 8 inches of accumulation is possible in advance of a cold front scheduled for tomorrow night.
