Special Announcements
The Avalanche Research Program at Simon Fraser University is conducting an online survey to examine how people use avalanche safety information. They want to hear from all backcountry users to understand how they process information provided in public avalanche forecasts. Anyone who completes the survey before May 15th will be entered to win cash prizes.
Weather and Snow
It's 31°F this morning at the 8400' Tony Grove Snotel, and there is 88 inches of total snow at the site with 126% of normal Snow Water Equivalent for the date. It rained in the mountains, and a few inches of heavy snow fell on upper elevation slopes in the Bear River Range in the past couple days, with nearly an inch of SWE. It's 24°F at the 9700' CSI Logan Peak weather station, and northwest winds are currently blowing around 15 mph.
Snow showers are possible this afternoon and tonight, but not much accumulation is expected. High pressure aloft will build across the Great Basin this weekend.

Avalanche Problem #1
Wet Snow
Type
Location
Likelihood
Size
Description
Rain on the snow, rising temperatures, high angled sun, and possible green-housing will cause increasing danger of loose wet avalanches on steep slopes during the day.
  • Rapidly warming temperatures, roller balls, pin wheels, and other natural or triggered loose wet avalanches are all red flags indicating wet avalanche potential.
  • If the snow you are riding in gets sticky and slushy or wet, it's time to move to someplace cooler or off and out from under steep hills.
  • Stay off and out from under large ridge top cornices, which could break much further back than expected and could trigger avalanches on slopes below.
Avalanche Problem #2
Wind Drifted Snow
Type
Location
Likelihood
Size
Description
A few inches of heavy snow fell at the highest elevations in the Bear River Range, and it was drifted into lee slope avalanche starting zones by fairly sustained westerly winds. Today and this weekend, people could trigger shallow avalanches of wind drifted snow and cornice falls on very steep upper elevation slopes facing the east half of the compass.
