current conditions The Tony Grove Snotel at 8400' reports 31°F, and there's 53 inches of total snow at the site containing 99% of normal SWE (Snow Water Equivalent). It's 13°F at the UDOT Hwy 89 Summit weather station, with light northeast wind. We found pretty good stability in the Tony Grove Area yesterday, but dangerous avalanche conditions exist in some areas where the snow is generally shallow, and large human triggered avalanches are possible.
I looked at a sled triggered avalanche and close call from 1/13/18 in the Tony Grove Area. A rather isolated event on very steep hill, NE @9100', 1' to 3' deep x 70' running on sugary facets just above Thanksgiving Crust. A small avalanche in big terrain. Looks like rider was caught and carried (or fell), but ended up on the surface with sled on the flank. |

recent activity A couple more large avalanches were unintentionally triggered yesterday in the Wasatch Range above Salt Lake City, and dangerous avalanche conditions persist in the backcountry. Besides the close call near Naomi Peak, no other avalanches were reported in the Logan Zone, but on Saturday, 1/13/18, I could see evidence of some sizable natural activity on the east side of the Wellsville Range. |

description
Although slopes are gradually stabilizing and persistent slab avalanches are becoming harder to trigger, the consequences remain the same. Dangerous persistent slab avalanches are possible on slopes with poor snow structure, which exist in many areas. Pay attention to possible signs of instability like cracking and whumpfing or collapsing, but remember these red flagged signs of instability aren't always present when avalanches are triggered.

weather High pressure over the Great Basin will start to weaken today. A weak system will cross the area late Tuesday through early Wednesday. A strong cold front will cross Utah Friday with a cold upper trof remaining over the area Saturday.
