Logan

There is CONSIDERABLE avalanche danger in mid and upper-elevation terrain. Natural avalanches are possible, and people are likely to trigger loose and soft slab avalanches of storm snow up to 2 feet deep on slopes steeper than 30°.

Evaluate snow and terrain carefully, make conservative choices, and continue to practice safe travel protocols. Avoid drifted slopes and large overhanging cornices.

March kicks off our Spring Campaign! If everyone in Utah’s backcountry community donates the cost of something they regularly enjoy on an adventure—like a dawn patrol burrito, a backpack snack, or post-ride trailhead drinks—we could fund not just one but two forecasters for the entire season!

Plenty of wet loose avalanches were visible in Logan Canyon yesterday, running into the Logan River below Temple Fork. There was lots of loose avalanche activity at upper elevations as well. We observed numerous loose dry avalanches of sluffs coming off the cliffs and steep slopes above Tony Grove Lake during periods of particularly heavy snowfall yesterday. The last reported large natural slab avalanche running on a buried PWL occurred on February 25.

Yesterday, the thick new snow was too deep in the Tony Grove Area to ski anything not steep enough to slide, and knee-deep trail breaking was arduous. But, we found excellent and super fun powder riding conditions in the meadows and on safe slopes less than 30° in slope steepness. Paige said she had more fun on the Ski-Doo than she's ever had before riding in powder.

No slab avalanches were reported yesterday, but we observed evidence of numerous natural loose avalanches of storm snow coming off the cliffs and steep slopes above Tony Grove Lake. We watched a few occurring during periods of particularly heavy snowfall. We also noticed several significant loose wet avalanches that ran during the day into the Logan River from the River Chutes below Temple Fork.

Soft slab avalanches of storm snow are a concern today in upper and mid-elevation terrain. We found a weak layer of graupel and rimed stellar snow flakes capping a thin melt-freeze crust from last week's warm temperatures. People are likely to trigger slab avalanches of storm snow up to 2 feet deep, especially on steep slopes where the new snow was drifted by moderate winds during the storm.

The Tony Grove Snotel at 8400 feet reports 7 inches of new snow in the last 24 hours, with 15 inches from the storm, containing 2 inches of SWE (snow water equivalent). It's 20° F, with 102 inches of total snow and the station sits at 112% of normal SWE for the date. There's 6 inches of new snow from yesterday and overnight, with 14 inches storm total at the Card Canyon weather station at 8800 feet. It's 16° F, and there's 75 inches of total snow.

At 9700 feet at CSI's Logan Peak Wx station, winds are blowing 11 to 15 mph from the northwest and it's 13° F. It appears to be a bit more windy in the northern part of the zone. On Paris Peak at 9500 feet, it's 10° F, with winds blowing 17 to 25 mph from the north.

The National Weather Service continued a Winter Storm Warning through this evening, but snowfall will taper off in the Logan Zone this morning. Light snow is falling this morning, but should wind down soon. It'll be mostly cloudy today, with high temperatures at 8500 feet around 28° F, and 8 to 13 mph winds from the north veering from the east this morning. Mostly cloudy skies will clear tonight, with a low temperature around 13° F and 8 to 13 mph wind from the north. Bluebird conditions with plenty of sun and warming temperatures are expected this weekend. Tomorrow will be sunny with high temperatures around 32° F and 6 to 9 mph wind from the north. It will be sunny and warmer still on Sunday, with upper elevation temperatures approaching 40° F.

Paige shows how much new snow accumulated yesterday in northeast facing terrain at 8800 feet in the Central Bear River Range.

We observed numerous loose avalanches of storm snow in the steep terrain above Tony Grove Lake. These were occurring yesterday during periods of particularly heavy snowfall.
