current conditions Beaver Mountain reports 32 F and 2 inches of new snow. Yesterday, the Tony Grove Snotel reported 96" of total snow and 151% SWE (Snow Water Equivalent) It's 23 F at the CSI Logan Peak weather station at 9700', and the wind is from the southwest at 33 mph, gusting to 56 mph. The snow on low elevation slopes was soggy from warmth, and there were many natural avalanches at lower elevations over the weekend. A moist and windy Pacific storm will begin to impact the zone today and will cause a rising avalanche danger in the backcountry. Rain on already wet snow at low elevations will create dangerous conditions, and natural wet avalanches are possible in steep terrain. Up higher, strong south winds are drifting the heavy new snow and triggered wind slab avalanches are increasingly likely. |
recent activity Several sizable natural loose wet avalanches hit the Logan River, and one crossed Hwy 89 in the Dugway section of Logan Canyon. Large natural wet avalanches occurred over the weekend at low elevations in various canyons across the Logan Zone. A wet avalanche hit Logan Canyon Hwy 89 in the Dugway in the middle of the day on Saturday. |

description
Dangerous wet avalanche conditions exist on slopes with saturated snow, and rain today below 6500' will not help the situation. Natural sluffs entraining loose wet snow are likely at lower elevations, and triggered wet slab avalanches are possible on slopes with buried persistent weak layers. Avoid and stay out from under steep slopes with wet snow. |

weather An active and rather wet pattern will continue into next weekend. Snow levels will mainly remain above 6500 feet through the work week. Temperatures will drop to 27 F at 8500' this afternoon, and it'll be quite windy, with west-southwest winds 31 to 36 mph gusting to 50 mph. 2 to 4 inches of snow is likely by evening. Temperatures will remain steady at 27 F tonight, southwest winds 20 to 30 mph with gusts to 45 mph are expected, and 6 to 10 inches of snow is possible. Snow will continue Tuesday and Tuesday night, with continuing southwest wind and another 7 to 13 inches of snow by Wednesday morning. |
