Avalanche Problem 1: Normal Caution
Likelihood ?CertainVery LikelyLikelyPossible
Size ?HistoricVery LargeLarge
Overall avalanche danger is low. Yesterday's storm was warm and wet and sent meager amounts of snow. There may be isolated wind slabs out there at high elevations, but they'll be small and hard to find. However, low avalanche danger should not give you license to turn off your head. Stay in the game. Pay attention as you ascend. Wind drifts, cracking, and blocking are signs that a wind slab may lurk nearby on a steep, leeward slope. Continue to bring your beacon, shovel, and probe. Practice safe travel techniques.
This year's annual super-spreader event, The Snowball, will be held online thanks to COVID-19.

Yesterday, by 1:00 p.m., there was about an inch of moist snow on top of a soft, melt-freeze crust near and above treeline. Snow levels started at around 6,200 ft and were rising. Whiteout conditions made for wonky traveling above treeline, though some enthusiastic folks were making a go of it. Even the most experienced were tipping over hilariously. We could get no eyes on the upper mountain.
All of our weather stations have been buried in the clouds and are reporting negligible snow accumulation. This means most precipitation in the last 24 hours was in the form of rain or wet snow. The Old Ski Bowl has received 0.25 inches of water, far less than the 1 inch forecasted. Temperatures were steady, averaging 31 ºF. Moderate westerly winds blew all afternoon and night.
