current conditions The 8400' Tony Grove Snotel reports 5 inches of new snow with .6" SWE (Snow Water Equivalent) in the last 24 hrs. It's 29 F and there is 96" of total snow containing 151% of average SWE. It's 23 F at the CSI Logan Peak weather station at 9700', and the wind is whipping from the south at 29 mph, gusting to 50 mph. Triggered wind slab avalanches are likely in drifted terrain and naturals are possible. Yesterday the snow on low elevation slopes was soggy from warmth, and rain today could create dangerous wet avalanche conditions on slopes with saturated snow. Roller balls and pinwheels like these from Tab Hollow yesterday are precursors to wet avalanche activity. |
recent activity It's been more than a week since any significant avalanches have been reported in the Logan Zone, but several small loose wet avalanches were observed yesterday in Logan Canyon. |

description
Rain on already wet snow at low elevations will cause an increasing danger of wet avalanches. Natural sluffs entraining loose wet snow are likely at lower elevations, and dangerous triggered wet slab avalanches are possible on slopes with buried persistent weak layers. Avoid and stay out from under steep slopes with saturated snow. |

After a brief break on Sunday, an active weather pattern will continue for much of next week. Snow showers are likely today, with 2 to 4 inches likely. The high temperature at 8500' is expected to reach 33 F, with west winds 20 to 25 mph. Snow is possible tonight, with a low temperature around 26 F, west winds 15 to 20 mph, and 1 to 2 inches of snow. Showery snow may continue through Sunday and Sunday night, with 8500' temperatures hovering around freezing and 2 to 4 inches possible. A bit stronger system will pass over the zone on Monday, with 3 to 7 inches of snow possible. |
