Forecast for the Ogden Area Mountains

Brett Kobernik
Issued by Brett Kobernik for
Sunday, March 10, 2013

An overall MODERATE avalanche danger remains today. This means human triggered avalanches are possible. Heating from the sun will make the snow unstable as the day progresses and the new snow along with recent fresh wind drifts may still be sensitive to the weight of a person.

Weather and Snow

North and northeast winds during the day on Saturday drifted the new snow to a certain extent in some locations but overall, the winds were better behaved than I thought they might be. They're from the north now and are light to moderate in speed in the low and mid elevations although they did blow a bit through the night. There's still some stiffer gusts up along the highest terrain. Temperatures cooled into the mid to low 20s overnight.

Avalanche Problem #1
Wet Snow
Type
Location
Likelihood
Size
Description

The first item of concern is how the new snow will react to today's sun. It's common that new snow events in the spring produce loose snow avalanches the first time the sun comes out after a storm. These don't pose much threat as they usually don't catch people after being triggered by someone, but, rather can catch the unwary traveler who is in confined terrain such as the bottom of a steep gully or coulior. It might be best to avoid hiking directly up steep chutes today.

Along with the warming comes the saturated and unconsolidated snow below around 8000 feet which may become more unstable as the day goes on. This is just another reason to avoid the steep confined terrain traps.

Avalanche Problem #2
Persistent Weak Layer
Type

Likelihood

Description

The new snow instabilities along with the fresh wind slabs should be more stable today however anticipate that they may still crack out. If you're in steep exposed terrain, you're in the type of place that this could cause you problems. Continue to do shear tests as you travel and perform slope cuts prior to just diving into your descents.

Additional Information

We'll be under a northerly flow over the next few days as a ridge of high pressure slowly makes it's way east into our area. Today we'll see mostly clear skies and ridgetop temperatures will be around freezing or a bit higher. North winds should remain in the moderate speed. We'll see some clouds Monday and Tuesday as moisture spills over the top of the ridge until the ridge is squarely over us mid week with continued warming. Weather models hint at a more active pattern for the latter part of the month but are quite erratic so confidence is low at this time.
