Forecast for the Ogden Area Mountains

Saturday morning, January 5, 2013

Most slopes have a LOW avalanche danger today. However, sluffing will occur as you travel on the steep, shady slopes at the mid and upper elevations and also on steep sunny slopes as the day heats up. Avoid all hard old wind drifts on steep slopes.

Weather and Snow

A string of beautiful mountain days continues – clear skies (need I add clean air?), very light winds and moderate temperatures are all reasons to grab a bus and head up high. The only single digit readings this morning are in the canyon bottoms – once you get out of these cold pockets, temperatures are generally near 20 at the mid elevations, with mid-teens along the high ridges. Winds are from a westerly direction, averaging less than 15 mph, with gusts rarely over 20 mph.

Steep sunny slopes are crusted this morning, but shady slopes have a deepening layer of soft, loose facets over a supportable base.

Recent Avalanches

Loose facet sluffs on shady slopes and damp sluffs on sunny slopes were the only backcountry avalanche activity reported yesterday. Resort explosive work released a few old hard wind slabs at upper elevations.

Avalanche Problem #1
Wet Snow
Type
Location
Likelihood
Size
Description

The loose snow sluffs are the most widespread avalanche concern today. These sluffs are just large enough to catch and carry you, with the greatest danger in the ride itself - being dragged through trees or over a cliff. This weak surface snow is most widespread on steep, shady slopes of all elevations.

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

Even with a LOW danger, on slopes steeper than 35 degrees always be thinking and defensively planning. Avalanche danger generally increases with elevation and steepness. Today:

  • Avoid the isolated hard, old wind drifts that could still crack out beneath you, and send you for a ride on steep slopes, mostly along the high elevation ridgelines
  • As the day heats up, the snow on steep sunny slopes could be released as a damp sluffs.
  • The buried mid pack weak layers seem dormant for the moment. They may be out of sight, but they should not out of mind – on steep, radical terrain, include the possibility of a slab avalanche in your defensive planning.
Additional Information

Utah is stranded in a Sargasso sea of high pressure – resulting in another consistent day of sunny skies and light winds. High temperatures today will be near 30 at 8,000’ and in the low 20s along the high ridgelines. The westerly winds will remain light, generally less than 15 mph, with the highest peaks gusting in the low 20s. There is a possible escape from the doldrums around next Wednesday, with strong southwesterly winds ahead of a fairly dry, but strong cold front forecast for Thursday.
