Logan

The avalanche danger is HIGH today, and travel in avalanche terrain is not recommended. Heavy snowfall, strong winds, and rising temperatures are creating very dangerous avalanche conditions. Human-triggered and natural avalanches are likely on all aspects and at all elevations.

• You'll find safer riding conditions on slopes less than 30 degrees.
• People fishing in the Logan River should avoid standing under steep slopes holding saturated snow.

What The avalanche danger for the warning area is HIGH at all elevations.

When: Very dangerous avalanche conditions will continue through the weekend and early next week.

Where: For the mountains of Northern Utah and Southeast Idaho, including the northern Wasatch Range and the Bear River Range.

Impacts: Heavy snow, drifting by strong winds, rising temperatures, and rain have created very dangerous avalanche conditions at all elevations in the backcountry.

Urgent battery replacement is required for anyone who received batteries from one of our participating "Batteries for Beacons" shops. Please review the replacement notice for "Batteries for Beacons" on our blog, HERE. Batteries distributed through our "Batteries for Beacons" program this year are of inadequate length. We apologize and will provide you with new batteries.

Avalanche conditions are becoming increasingly complex. In the past 36 hours, we’ve received 2.5" of SWE (snow water equivalent) and 14 inches of heavy snow, accompanied by strengthening winds and a rising rain/snow line as temperatures warm. The storm snow is loading on widespread pre-existing weak snow across the range, creating very dangerous avalanche conditions. Avoid all avalanche terrain and stay clear of avalanche runouts. You'll find good dense powder riding in the meadows and on low-angle slopes less than 30 degrees not connected to steeper terrain. Expect to see natural loose wet avalanches on steep slopes below 8000' on all aspects as temperatures rise today. ***Fisherpeople beware of avalanches coming down into the river.

-The Tony Grove Snotel at 8400 feet reports 34° F, with 68 inches of total snow and 12 inches of new snow in the past 24 hours containing 1.8" SWE.

- At our Card Canyon weather station at 8800 feet, it's 31° F and there is 47 inches of total snow.

-At the CSI Logan Peak weather station at 9700 feet, winds are blowing from the southwest 35 to 45 mph with gusts in the 60's mph, and it's 28° F.

- On Paris Peak, at 9500 feet, it is 25° F, and the winds are blowing from the south-southwest 24 to 39 mph.

The National Weather Service has continued a Winter Storm Warning for the Logan area mountains through 5 pm today. Another 3 to 8 inches of wet, heavy snow is expected, with strong winds blowing from the southwest, gusting up to 45 mph. The rain/snow line may reach as high as 8000', so be prepared for wet weather. The system will move on by tomorrow morning, but the unseasonably warm air is expected to stay for a few days. The next chance for snow is Tuesday night into Wednesday.

We found widespread weak snow on and near the snow surface in the Tony Grove Area Wednesday. The current storm is overloading this poor structure, and both human-triggered and natural avalanches are very likely.
