bottom line The danger will rise to MODERATE on upper elevation slopes that receive significant moist snowfall today. You could trigger shallow persistent slab or storm snow avalanches on steep northwest, north, and northeast facing slopes at upper elevations. Continue to use safe travel protocols, check your avalanche rescue equipment, and find the time to practice avalanche rescue scenarios with your partners....

current conditions The Tony Grove Snotel reports a a little more snow overnight, and there is 9 inches of total snow at the site. Southwest winds are averaging in the mid teens at the CSI Logan Peak weather station at 9700' where it is already 29 degrees. You'll find very shallow early season snow cover in the Logan Zone, with fresh moist powder conditions limited to a few north facing upper elevation slopes with smooth underlying ground. Keep the speed down and watch for shallowly buried rocks and stumps. It's still far too shallow for riding sleds in the backcountry. Be sure to check your batteries and the working condition of your rescue equipment, practice rescue scenarios with your partners, and always follow safe travel protocols.... Remember that the Tony Grove Road is not maintained for winter travel and is likely to present winter driving challenges... Be sure you are prepared with shovels and other emergency supplies.

.Shallow persistent slabs exist in some exposed terrain... Overloaded by today's moist snow, these slabs may be sensitive to your weight on very steep slopes, and in some cases could fail on weak underlying October snow near the ground.... Be very wary of any red flags indicating unstable snow like audible collapsing or shooting cracks, which are sure signs of lurking danger.... |

Storm snow avalanches may become possible on steep slopes in areas that receive significant snowfall today.. Soft slabs and sluffs could entrain a good deal of snow, and you do not want to be taken for a traumatic ride through shallowly buried rocks and dead-fall in avalanche run-out zones. |

weather The National Weather Service has issues a Winter Weather Advisory for the mountains in our area. Several inches of heavy wet snow will accumulate on upper elevation slopes, with snowfall intensifying around midday and continuing through tonight. 20 mph southwest winds and 4 to 8 inches are forecast today, with a few more tonight. Mountain temperatures will remain on the mild side and we should expect continued rain below around 7500' in elevation. A dryer air mass will move into the region on Monday as a short-lived high pressure system builds. The mild southwest flow will kick in again and remain in place for much of the coming week, with a weak and dry system forecast to affect far Northern Utah on around Wednesday...
