Avalanche Advisory
Advisory: Logan Area Mountains Issued by Toby Weed for Monday - March 23, 2015 - 6:58am
bottom line

LOW (Level 1): The snow is mostly stable, especially in areas where it's solidly refrozen, but heightened wet avalanche conditions may develop on some steep backcountry slopes due to rain-on-snow at mid elevations, and as daytime temperatures warm into the 40s.

  • Use normal caution, continue to follow safe travel protocols, and carry your avalanche rescue equipment.
  • Evaluate the snow and terrain carefully, especially near cliffs or under cornices.

Special thanks to Buttar's of Tremonton and ArcticCat for hooking us up with the light and powerful M8000,
current conditions

We're likely to see a little snow in the mountains today, and I expect the snow on most slopes will stay fairly solid with cloud cover, cooler temperatures, and a westerly breeze. The Tony Grove Snotel reports an inch of snow overnight and 54 inches of total snow containing 75% of average water for the date. Temperatures did not drop below freezing in many areas last night again, but it appears to be cooling off a little in the last couple hours. It's 31 degrees at 9700' CSI Logan Peak, which is the overnight low. Temperatures appear to be hovering around freezing at the UDOT Hwy 89 Summit weather station, with light easterly winds overnight.
recent activity

Widespread natural loose wet avalanches occurred across the Logan Zone during the heat of the day last week, and riders reported observing a couple more sizable avalanches at upper elevations and on east facing slopes near the state line on FrIday.

Rain is possible at mid elevations and after yet another night without a good refreeze, wet avalanches may be possible again in some steep terrain today, especially during the midday warmth, (and we are expecting upper elevation temperatures in the 40s.) Continue to avoid shallow or rocky areas with melt-softened and saturated snow.

Avalanches are generally unlikely and it seems like May, but it's still March and barely spring, so we still need to be thinking in terms of avalanche safety in the backcountry.

  • Continue to practice safe travel protocols. Go one at a time in avalanche country, while the rest of your party watches from a safer area.
  • Continue to carry your avalanche rescue equipment, (beacon, probe, and shovel) and the longer days of springtime give us more time for critical practice of Companion Rescue techniques with our backcountry partners.
weather

Snow is likely in the mountains today, with 2 to 4 inches of accumulation possible. Expect 10 to 20 mph southwest wind and temperatures in the upper thirties on the highest peaks. Snow showers will likely continue into tonight, with another 1 to 3 inches of snow possible, temperatures dropping into the lower twenties, and moderate west-northwest winds. Snow is expected again tomorrow in the mountains, with cooler temperatures, increasing and sustained west-southwest wind, and 3 to 7 inches of additional accumulation possible.
