Advisory: Logan Area Mountains | Issued by Toby Weed for March 13, 2013 - 7:06am |

Above 8,500 ft.
7,000-8,500 ft.
5,000-7,000 ft.

bottom line Rapidly rising and very warm mountain temperatures will create heightened avalanche conditions and a MODERATE (or level 2) danger in the backcountry today. Wet and heat related avalanches will become increasingly possible as the day warms and saturated snow softens. Avoid steep terrain with saturated snow, and plan on an early departure from the backcountry due to rapidly warming snow. Today's warming will cause a general increase in avalanche danger. Dangerous persistent slab avalanches are still unlikely but increasingly possible in isolated outlying terrain with poor snow structure, and you might trigger wind slab avalanches or cornice falls in drifted upper elevation terrain. Evaluate the snow and terrain carefully, and avoid areas with soft and saturated snow, shallow rocky terrain, and steep drifted slopes.

special announcement Go to http://www.backcountry.com/utah-avalanche-center to get tickets for Beaver Mountain. You won't save a ton of money, but all proceeds from sales of these tickets will benefit the Utah Avalanche Center, and It's super easy to do. |
current conditions The Tony Grove Snotel at 8400' reports 33 degrees, and with 59" of total snow, the station sits at 67% of average water for the date. The CSI Logan Peak weather station at 9700' reports 29 degrees and west-southwest winds picked up overnight and are averaging in the low to mid twenties with gust of 37 mph early this morning. You can still find fairly nice somewhat dry snow on north facing slopes at upper elevations, but the snow is pretty wind jacked in exposed terrain and elsewhere sun and warm temperatures created crusty or soggy snow conditions....

recent activity A rider triggered a small wet slab avalanche on a west facing tailings pile yesterday at the quarry in lower Providence Canyon. Otherwise no avalanches were reported recently in the Logan Zone Here's a link to our updated Avalanche List.

description
The temperature at the Campbell Scientific Logan Peak weather station is already a couple degrees above yesterday's high, and the forecast 46 degrees for 9000' will be around 10 degrees warmer than yesterday. Wet and heat-related avalanches will become possible as the day warms and as the saturated snow at lower elevations softens up. Avoid steep terrain with warmth softened and saturated snow today, watch for potential terrain traps below steep slopes, and plan on an early departure from the backcountry due to rapidly warming conditions.....

Be aware that today's rapid warming will also cause a general increase in avalanche danger...

weather Expect mostly sunny skies, with a southwest breeze and 9000' high temperatures around 46 degrees. Temperatures should drop to around freezing tonight with partly cloudy skies. Expect even warmer conditions tomorrow, with 9000' temperatures forecast at 52 degrees... We'll see a few clouds on Friday and perhaps a few degrees cooler temperatures. There is a chance for a little snow over the weekend and clouds will likely cool things down a bit..... Check out the Logan Mountain Weather page...
