Logan

Avalanches are unlikely and the danger is LOW in the backcountry. Even so, people might trigger shallow slab avalanches of drifted snow on very steep upper elevation slopes, and loose wet avalanches entraining moist surface snow are possible in steep sunny terrain.

USE NORMAL CAUTION

Thank you to everyone who helped make our Spring Campaign a huge success. We are grateful for your donations and what they will allow us to accomplish next season. We look forward to continuing to serve you with our forecasting, education, and awareness programs in new and exciting ways.

The excessive heat last weekend caused natural wet avalanche activity to occur on steep slopes in the Logan Zone, including this nice wet avalanche in Drop-in, Drop-out in Lower Logan Canyon.

This natural wet avalanche in Lower Logan Canyon was observed last Sunday on a north facing slope at around 8000' in elevation.

It's 17°F this morning at the 8400' Tony Grove Snotel, and there is 53"of total snow containing only 62% of normal SWE. Winds from the northwest are blowing around 15 mph, and it's 11°F at the 9700' CSI Logan Peak weather station.

The sun will be out in full force again today, and it looks like fair spring weather will last through the weekend. High temperatures at upper elevations will top out around 36°F today, and a light north breeze will blow across the ridges and veer from the west this afternoon. It will be a clear night tonight, with mountain temperatures dropping into the mid twenties and a southerly breeze. Southwest winds will increase tomorrow afternoon, the sun will be out, and high temperatures will be around 45°F. It'll be clear and sunny, but a bit cooler in the mountains on Sunday. Monday will also be sunny, but more unsettled conditions with snow showers will develop as we head into next week.

General Spring Travel Advise:

As daytime temperatures rise, softening the snow, the danger of wet avalanches will increase, so its a good idea to get in the habit of an early start and to plan on heading down before things get too sloppy.

-Watch for trees or other terrain traps below you if you venture onto steep slopes.

-Roller balls, pin-wheels, and natural wet avalanche activity are red flags indicating potential for people to trigger wet avalanches.

-If you start sinking deeply into wet snow, or if the snow you are traveling on becomes unsupportable due to the heat, it's time to leave. More dust was blown onto the snow surface by strong northwest winds yesterday evening. Dust from previous events is a significant player in the early melt-down this spring.

The dust melted through the shallow new snow already in most mid elevation terrain and the snow surface is rough and mottled.

With all the dust and a snowpack with well below average SWE, Beaver Creek is melting out a few weeks earlier this spring than it did last spring.
