Highlights

The avalanche danger is MODERATE at the upper elevations where there are pockets of wind-drifted snow. Smooth, rounded pillows of snow are signs of wind-drifted snow and cracking is evidence of instability.

There is a LOW danger at low and mid elevations.

Pockets of recent and fresh wind-drifted snow can be found on all aspects along upper-elevation ridgelines. Several observers in the Salt Lake mountains found wind-drifted snow and small cornices reactive on Thursday and, although they may be less sensitive today, I am expecting pockets of sensitive wind-drifted snow can still be found at the upper elevations. Watch for cracking in the wind-drifted snow, such as shown in the photo below from Weston Shirey's observation from upper Little Cottonwood, as an indication of sensitive conditions.

Trend: Decreasing danger.

Additional Info

A Few Things to Remember:

Whether you're-hiking, hunting, skiing, boarding, snowshoeing or on a snowmachine, be prepared for avalanches
Any avalanche can produce serious trauma because of a thin, early-season snowpack
Hitting rocks and stumps remains a real danger. Don't end your season early.
Treat ski resorts as backcountry terrain and check out the UAC site for resort uphill travel policies

Special Announcement

Many ski areas are now closed to uphill travel in order to prepare for winter operations. Resort uphill travel policies can be found HERE.

Recent Activity

We received no observations from Thursday. On Wednesday, Drew joined snow safety professionals at Powder Mountain and his observation provides an excellent evaluation of the current snowpack around Powder Mountain.

Please submit your observations as we try to collect more data for the Ogden-area mountains.

Further south in the Salt Lake mountains, several observers found pockets of sensitive, wind-drifted snow at the upper elevations, including on a southeast aspect at 9,500' on Flagstaff Ridge that was 7" and 50' wide (photo below) and I expect similar conditions can be found along exposed ridgelines in the Ogden mountains.

Snow and Weather

Snow: Some mountain locations picked up a dusting of light snow late yesterday, with storm totals since Monday of 20-30" of snow containing over 2" of water.

Currently: Temperatures this morning are in the low teens and winds from the west/northwest and light, averaging less than 10 mph with gusts in the teens at mid elevations.

Today: Mostly sunny with a few clouds. Temperatures will rise into the mid 20's F and the northwest winds will remain light, gusting into the teens at mid elevations and into the mid 20's mph at the highest elevations. High-level clouds will increase late in the day and winds will remain generally light, backing to the south and southwest for Saturday as a weak system that only delivers a few clouds moves through. High pressure builds behind this weak system. Unfortunately, we see no new snow in the extended forecast period.

The Week in Review is centric to the Salt Lake mountains and will appear regularly by early to mid-December, but given the impressive storm cycle over this past week, we have published a special early November edition.
