Logan Avalanche Advisory

Forecaster: Toby Weed


Please join the Friends of the Utah Avalanche Center in Logan for our annual "Pray for Snow" Fundraiser and Party on Wednesday November 30th at the Italian Place in downtown Logan. The event will feature a silent auction, raffle, great food, music, and a special presentation by Bruce Tremper, the Director of the Utah Avalanche Center.Please call 757-2794 for more info.

Danger Rose Tutorial

Despite shallow early season snow cover, heightened avalanche conditions still exist in the backcountry. You could trigger avalanches and there is a level 2 or Moderate danger on steep drifted slopes at upper elevations... The most significant danger remains on steep north facing slopes at upper elevations where very dangerous triggered persistent slab avalanches are still possible. Triggered wind slabs and loose wet avalanches are also possible in steep terrain... Evaluate the snow and terrain carefully, especially in drifted northerly facing upper elevation terrain....


We found nice riding conditions over the weekend in graupel and a few inches of drifted but fairly smooth fresh snow.... Riders report rocky conditions in off road terrain, and you need to stay on roadways or smooth grassy upper elevation meadows to avoid damaging your sled... The snowpack is getting weaker and less supportable, so it's pretty easy to bog down and get stuck in sugary baseless snow if you get off the beaten track and lose momentum.

The Tony Grove Snotel at 8400' reports a balmy 39 degrees this morning and 29 inches of total snow on the ground.. It's 32 degrees at the 9700' CSI Logan Peak weather station, with a west wind this morning averaging around 20 mph. Overnight winds at the station averaged in the thirties for a couple hours overnight, with a gust of 46 mph reported early this morning.


No new avalanches were reported recently in the Logan Area...


      Over the next 24 hours.

With significant sublimation occurring over the past several days, the snowpack continues to weaken and the tension in the slabs appears to be relaxing. Even so, there are slopes with suspect snow structure, and persistent hard slabs could still be triggered on some steep north facing slopes at upper elevations. Be especially wary in rocky or shallow areas that held October snow before the big mid November storms. The consequence of being caught in an early season hard slab avalanche is greatly increased by the shallowly buried and exposed rocks you could be raked over...


      Over the next 24 hours.

With fairly strong west winds overnight and in the past several days, you'll likely find drifts and stiff stubborn wind slabs in deposition zones like the lee sides of ridges and sub-ridges, in gullies or scoops, near rock outcroppings, and under cliff bands... Avoid smooth rounded or chalky looking or hollow sounding drifts on steep slopes...


      Over the next 10 hours.

Warm temperatures at upper elevations have created the possibility of loose wet avalanches on steep slopes with saturated surface snow. If the snow you're on is saturated and soft, you might trigger small wet avalanches on steep slopes... Make sure no one is below you, and move to lower angled or shady terrain....


Thin high clouds will thicken up today as a mostly dry and weak cold front moves over the area... Don't expect much in the way of accumulation, but we could see a snowflake or two from this system and mountain temperatures should cool down. The high pressure system will rebuild on Tuesday.. The next somewhat more energetic front will affect our area on Wednesday and Wednesday night, and we could pick up a few inches of snow.... East or down canyon winds may become an issue after the frontal passage... Forecasters are unsure of next weekend's weather outlook, as there is a fair amount of difference of opinion between the models....
