Forecast for the Ogden Area Mountains

Brett Kobernik
Issued by Brett Kobernik for
Friday, December 21, 2012

A MODERATE Avalanche Danger exists on all steep, mid and upper elevation northerly through easterly facing slopes. There is a chance of triggering an avalanche that breaks into deeper weak layers. Deeper snowpack areas are safer but new windloading is a distinct concern today in these areas also.

Weather and Snow

Temperatures are up and so are the winds. We have 25 to 30 degrees along the ridges and southwest winds a little stronger than yesterday during the day with moderate speed gusts along the mid elevations and gusts into the 50s and 60s along the more exposed terrain. Upper elevation snow surface conditions have deteriorated but mid elevations remain excellent.

Avalanche Problem #1
Persistent Weak Layer
Type
Location
Likelihood
Size
Description

Fresh wind drifts that may release under the weight of a person or a sled is your first order of business today. Be leery of those fresh pillows or any slope that sits below a plume coming off a ridge. Primary suspect aspects are north through east but watch for loading on all aspects as the wind can stir the snow up quite randomly.

Avalanche Problem #2
New Snow
Type
Location
Likelihood
Size
Description

The more dangerous but not as likely to occur problem is buried weak snow. Thinner overall snowpack depths on north through east aspects are the most likely spots to see this and the recent wind loading only increases the danger.

Additional Information

It's going to be a bit blustery today with continued southwest winds in the moderate range along the mid elevations and stronger gusts up high. Temperatures will remain fairly mild with highs in the mid to upper 20s along the ridges. We'll see some increasing clouds and continued southerly winds on Saturday ahead of a mild disturbance and then a better looking storm for Sunday night through Monday with hopefully another foot of new snow.
