Mountain temperatures stayed well above freezing overnight again, and temperatures will climb above 60°F at upper elevations today. Dangerous wet avalanche conditions and CONSIDERABLE danger exist on many steep slopes. People are likely to trigger loose wet avalanches. Significant natural wet avalanche activity and dangerous wet slab avalanches are possible on very steep slopes, especially near cliffs or rock bands, but anywhere where the rapidly melting snow is soft and saturated. AVOID TRAVEL ON OR BELOW STEEP SLOPES WITH MELT-SOFTENED SATURATED SNOW

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.

We observed a handful of recent natural wet loose avalanches in the Wellsville Mountain Wilderness Thursday, and we were easily able to trigger wet sluffs on sunny slopes by early afternoon. From Cache Valley, we could see additional natural wet loose avalanche activity both Friday and Saturday.

Natural wet avalanches initiate from saturated snow falling off rocks or cliff bands and then they entrain more saturated surface snow as they run down the slope. These can get pretty big on sustained slopes.

It's way too warm again this morning, and dangerous wet avalanche conditions exist in steep terrain again today. Clouds trapped the heat in the atmosphere last night, and today's exceptionally warm weather will create dangerous wet avalanche conditions on very steep upper and mid elevation slopes facing all directions, not just on sunny slopes.

It's 45°F this morning at the 8400' Tony Grove Snotel, and there is 57 inches of total snow containing only 72% of normal SWE. I'm reading a toasty 43°F and winds from the south are blowing around 20 mph at the 9700' CSI Logan Peak weather station. Exceptionally warm weather will continue today, with clouds this morning giving way to plenty of sun in the afternoon, and a breeze blowing from the southwest. High temperatures at 9000' in elevation will likely be over 60°F today.

Temperatures will drop during the day tomorrow with increasing clouds and southwest winds. Snow showers are likely and thunder-snow is possible Monday night, with mountain temperatures forecast to drop to around 22°F, fairly strong westerly winds, and 3 to 5 inches of accumulation possible on upper elevation slopes in the northern part of the Logan Zone. A few more inches of snow could accumulate on upper elevation slopes on Tuesday, and daytime temperatures will warm up again as we head further 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.

-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. Do you have the essential avalanche rescue gear (transceiver, probe, and shovel) and do you know how to use them? Watch this video to see how the three pieces of equipment work together. HERE

Please keep practicing with the Beacon Training Park at the Franklin Basin Trailhead. Test yourself and your riding partners. It is free, fun, and easy to use.
