Advisory: Logan Area Mountains | Issued by Toby Weed for Thursday - February 18, 2016 - 7:24am |

special announcement We are offering an Avalanche Awareness for Snowmobilers Course on February 25 & 27. For more information and to register go..... HERE

current conditions Expect dropping temperatures and very strong west winds in the mountains, rain (at least this morning) below about 7500', a shot of heavy snow at upper elevations (3 to 7 inches of accumulation), and possible thunder and lightning. The 8400' Tony Grove Snotel reports 35 degrees this morning and there's 72 inches of total snow containing 101% of average water content for the date. I'm reading 28 degrees at the 9700' CSI Logan Peak weather station, and south winds averaging almost 45 mph and gusting to 76 early this morning. The snow at mid and lower elevations yesterday was still very soft, inverted, and saturated by rain. Lacking a good overnight freeze again and with a bit of rain forecast today, dangerous wet avalanche conditions will again probably exist at lower elevations. Observers have noted a rime-crust at upper elevations, which appears to be thicker as you head north... In some areas the ice-crust capping loose powder situation is making for very challenging and perhaps dangerous riding conditions.. A 2" thick coating of rime ice coveres a small Limber Pine in open upper elevation terrain near Naomi Peak in the Tony Grove Area. (Wolford 2-16-16)

description
Wet avalanches are likely again today at low elevations as rain continues to dampen the existing weak and already saturated snow. Cooler temperatures and perhaps a good freeze tonight will help to solidify and stabilize the loose wet snow, but significant loose wet avalanches involving saturated soft snow remain likely on steep slopes below the rain/snow line... Dangerous triggered wet slab avalanches are possible in some low elevation areas with saturated snow and poor snow structure. |

description
A thick rime or rain crust formed up at upper elevations in many areas and appears be welding most of the existing wind slabs in place, but new drifts will quickly form as heavy snow accumulates during very strong west winds. Expect to find drifts forming well off ridge lines and perhaps in unexpected places.
