Avalanche Advisory
Advisory: Ogden Area Mountains Issued by Evelyn Lees for Sunday - March 27, 2016 - 6:45am
bottom line

The avalanche danger is LOW this morning, but will rapidly rise to MODERATE danger with daytime heating. The snow on all aspects and elevations but high north will heat and become damp, and both human triggered and natural wet loose avalanches will be possible. Avoid travel on and below steep, warming slopes.

Spring powder special! We have reduced the price of donated Snowbasin lift tickets to $50 and Sundance tickets to $35, about half of window price. Take advantage of fresh powder on a fat snowpack and benefit the Utah Avalanche Center at the same time. We also have one remaining Snowbird ticket for $84. Every penny spent on these donated tickets benefits the Utah Avalanche Center.
current conditions

Under partly cloudy skies, temperatures are in the teens to upper 20s, giving the snow a good overnight refreeze; also creating “slide for life” conditions on the hard crusts. The winds have shifted to the southwest ahead of the next storm – with speeds along the high ridge lines in the Ogden area mountains averaging 25 to 35 mph averages, and gusting in the 30s.

recent activity

No new avalanche activity reported from the Ogden area mountains, but plenty of excitement to the south. In Broad’s Fork, a glide avalanche narrowly missed 5 people in 2 parties by about 5 minutes; in Deaf Smith, a wet loose slide came down from above onto a party of 3 – one person was caught and carried, but is OK. It’s unknown if this was a natural or triggered by another party summiting Bonkers. And finally, a small soft slab avalanche was triggered in the Monitors.

With a rapid warm up and mix of sun and clouds, wet loose sluffs will be the number one concern today. I expect the snow to heat on all slopes but upper elevation northerly facing. Damp snow, roller balls and triggering wet loose sluffs are all signs it’s time to get off and out from under the steep, heating slopes and stay off of slopes ending in gullies. Head to a different cooler aspect or lower angle terrain, and be aware of what’s above you - natural wet avalanches are possible today.

Wind slabs – there could still be a few isolated places where a person could trigger a wind drift along the higher ridgelines.

The heating cornices are sensitive – avoid travel beneath them, and stay back further from the edge than you think you need to.

Glide avalanche – avoid travel below glide cracks, often on slopes underlain by smooth rock slabs. This includes known areas such as Broads Fork, Mill B, and Mineral Slabs, and some of the smooth rock slabs in the Ogden area mountains.

weather

Skies will be partly to mostly cloudy today, and temperatures very warm, soaring to near 50 at 8,000’ and into the upper 20s at 10,000’. The southwesterly winds will increase slightly, with averages reaching 25 mph in the high alpine, gusting to 40 mph. Overnight, the winds will really ramp up, with speeds across the high peaks averaging to 40 mph, and gusting in the 70s. Snow will begin early Monday morning as a large storm system brings periods of snow through Wednesday. Confidence is very low as to where the front will stall, so the forecast of 14 to 28 inches of snow by late Wednesday is broad for a storm total
