Logan

Pockets of MODERATE danger exist, and people could trigger shallow wind slab avalanches on upper elevation slopes steeper than 30°.

***A powerful winter storm beginning tonight will rapidly elevate the avalanche danger in the backcountry. With widespread weak faceted snow plaguing many slopes, dangerous avalanche conditions will develop.

This map from the National Weather Service shows expected snowfall for the next few days...

Today, increasing winds from the south will elevate the avalanche danger in drifted upper elevation terrain, generally on northerly facing slopes that are steeper than 30 degrees. Shallow hard slabs of wind-drifted snow may be sensitive to your weight in lee areas of exposed ridgelines and in and around terrain features, such as gullies and rock bands. Terrain below about 7000 feet has only very shallow, if any, snow cover, with muddy access trails, dry trailhead parking lots, and sunny slopes facing southeast through west completely bare of snow.

Currently, winds on Logan Peak are blowing from the south, 30 to 45 mph. It's 22°F on Paris Peak at 9500 feet, and the wind is blowing 10 to 15 mph from the south, with overnight gusts around 30 mph. At 8700 feet, the UAC Card Canyon station reports 27°F, and there's 43 inches of total snow. The Tony Grove Snotel, located at 8400 feet, reports 30°F, with 54 inches of total snow.

The National Weather Service has issued a Winter Storm Warning for the mountains in the Logan Zone, beginning tonight through Wednesday night. We can expect mostly sunny skies in the mountains today, with high temperatures at 8500' around 38°F and winds from the south-southwest blowing 15 to 24 mph, with gusts as high as 45 mph. A powerful winter storm starts tonight, and snowfall could be heavy at times, with the temperature dropping to around 21°F and 6 to 10 inches of accumulation possible up high. Significant drifting will occur, with a wind from the south-southwest blowing 25 to 33 mph, and gusting as high as 55 mph. Heavy snowfall and strong winds will continue tomorrow, and some thunder is also possible, with 7 to 11 inches of accumulation possible. Expect high temperatures near 25°F, with a wind from the west-southwest 24 to 32 mph, with gusts as high as 55 mph.

• Travel with a partner, and cross or ride slopes steeper than 30 degrees one at a time while the rest of your group watches from a safe spot.
• Ensure that everyone in the group has avalanche rescue equipment (a transceiver, probe, and shovel) and knows how to use it.
