Avalanche Advisory
Advisory: Ogden Area Mountains Issued by Evelyn Lees for Saturday - March 15, 2014 - 7:04am
bottom line

The AVALANCHE DANGER is MODERATE on any steep slope with drifts of wind-blown snow. While the drifts are most widespread in upper elevation terrain, there will be a few drifts on mid elevation slopes due to the strong winds. Out of the wind affected terrain, the avalanche danger is mostly LOW.

current conditions

A cold front zipped through northern Utah last night, it was accompanied by strong northwesterly winds. Sustained speeds were the 25 to 40 mph range, and gusts were in the 60s. So the 1 to 3 inches of dense snow the front left in its wake have been blown all over, leaving a matrix of scoured, icy patches, soft snow on northerly facing slopes and scattered shallow drifts. Temperatures have dropped behind the front, and are in the low 20s along the high ridge lines, and in the upper 20s to low 30s at the low to mid elevations in the Ogden area mountains. The west to northwesterly winds are still brisk this morning – 15 to 25 mph averages, gusting into the 40s.

recent activity

The backcountry was mostly quiet yesterday, though one decent size wet loose sluff was reported from the Provo area mountains. It was on an easterly facing slope at 7,000’. In addition, a few new snow soft slabs were triggered with explosives in the Ogden area mountains. These were on northwest through northeasterly facing slopes, and large enough to catch and carry a person.

Today’s greatest concern will be the shallow, new wind drifts. These will be most sensitive where they are sitting on the soft, slightly recrystallized old snow on the northerly and easterly facing slopes. While these drifts will be shallow, triggering even a small one in very steep or radical terrain could send you for a long ride or off a cliff. If you see a scoured area, be thinking “where did that snow go?” – work hard to identify and avoid any wind drifts on steep slopes. Again, and excellent observation of a skier triggered slide on Monte Cristo from last Wednesday. DETAILS .

Out of the wind affected terrain, there is a mostly LOW danger, though avalanches can still be triggered in isolated places -

  • Dry snow sluffs can be triggered on a steep, upper elevation, northerly facing slopes, that are just large enough to take a person for a ride in steep terrain.
  • It will be slow to warm today, but the snow on a few steep, wind sheltered sunny slopes could heat up just enough that a person could trigger a wet sluff.
  • And there is always an outlier – in rocky, shallow snowpack areas, there are still isolated places where a slab failing on facets could be triggered. The most recent was on Wednesday in the Salt Lake mountains.
  • The buried layers of graupel I looked at yesterday seemed unreactive, but could be a weak layer in very isolated places.
  • With another potentially busy day in the Wasatch, keep an eye on the location of other parties, stay spread out, and try to avoid having more than one person at a time on steep slopes.
weather

High pressure is building in for the weekend. Skies will rapidly clear this morning, and temperatures warm into the upper 30s at 8,000’ and the low 20s along the high ridgelines. The pesky northwesterly winds will be slow to decrease, with highest ridgeline stations still averaging about 25 to 30 mph, gusting to 40 mph, until about noon.

Sunday will be another warm, sunny day, followed by another fast moving storm late Monday that should be good for another few inches of snow.
