Advisory: Logan Area Mountains | Issued by Toby Weed for Monday - February 26, 2018 - 7:04am |

current conditions Recent cold temperatures preserved the nice powder from last week, and another 10" or so fell over the weekend. Several more inches of snow is expected to fall in the mountains today. Strong southwest winds are a problem. The light powder is easily picked up and drifted into lee slope deposition areas and upper elevation avalanche starting zones. You'll find excellent backcountry powder riding and skiing in sheltered, lower angled, and lower elevation terrain, but use a heightened degree of situational awareness because human-triggered avalanches are likely on drifted upper elevation slopes.

recent activity Yesterday's increase in westerly wind caused natural cornice fall avalanche activity, and we have reports of a few intentionally triggered wind slabs in drifted terrain. |

The recent fresh powder is so light it is easily drifted into avalanche starting zones. Human triggered wind slab avalanches are likely today in drifted terrain.

Avoid ridge-top cornices, which often break further back than expected and can trigger avalanches on drifted slopes below.
A natural cornice-fall triggered avalanche hit Tony Grove Lake with soft debris on Sunday, 2/25. |

Areas with heightened persistent slab avalanche conditions exist at upper and mid elevations, mainly in drifted terrain. Dangerous human triggered avalanches stepping down into buried persistent weak layers are possible.

weather A developing upper level low pressure system over California later today will eventually turn east and track across Arizona midweek. Precipitation on the periphery of this low pressure system will impact northern Utah through Tuesday, then southern Utah midweek. A significant winter storm will reach the Great Basin for late in the week through the upcoming weekend.
