current conditions Winter is trying to arrive - since December 22 the Provo area mountains have received over a foot of snow, with probably closer to 1 1/2 feet up high. Under partly cloudy skies, temperatures are in the teens to mid 20s this morning. Winds are from a westerly direction, averaging 5 to10 mph at the mid elevations, with average speeds up to 20 mph at the higher elevations. |
recent activity No new avalanche activity has been reported from the Provo area mountains. But...if you are heading to the Cottonwoods or Park City side, take note: Yesterday, backcountry avalanche activity included slides triggered remotely from a distance on Reynolds Peak and a large slide triggered from below in Porter Fork. These broke on layers of weak, sugary faceted snow. Avalanche reduction work at the Cottonwood resorts resulted in many large avalanches from both explosives and ski cuts, some breaking mid-pack or to the ground. Many were running long distances and some of these were large enough to break a few trees. All elevations on the northerly facing slopes were active, including elevations below 9000 ft.

description
Collapsing, cracking and avalanches. These are the bulls eye clues to watch for in the upper elevations of the Provo area mountains. These weak faceted layers will be very slow to stabilize, and avoidance is key. The facets are most widespread on northwest through easterly facing slopes at the upper elevations. So avoid travel on and below all steep slopes, including even the smaller, steep gullies, creek beds and road banks at the mid elevations.

description
While more stubborn, wind drifts could still be triggered on steep slopes today – most widespread along or just off ridgelines. Once any snow gets moving, it could step down to one of the deeper weak layers, resulting in a much larger avalanche. |
weather We will be under a dry and mild west to northwest flow through the end of the week. Today, skies will be partly cloudy to sunny. Temperatures will be warm – reaching into the twenties to mid 30s today. Winds will mostly be light, in the 10 to 20 mph range, though the 11,000’ winds may gust into the 50 to 60 mph range at times. |
