The avalanche hazard is moderate at all elevations.  Human triggered wet loose avalanches are possible on slopes steeper than 35° where more than 4 inches of slushy snow is present.  Avalanches could be small to moderate in size depending upon the the vertical fall of the slope that they originate from.  Although unlikely there is also a chance to trigger a large wet slab avalanche that could be large enough to injure, bury or kill a person.  There are often good indicators in the spring that wet avalanche activity is becoming likely.  These include: pinwheels or rollerballs at the bottom of slopes, a snowpack that can no longer support a persons weight on their feet and steep rocky terrain producing wet loose or slab avalanches.  Thompson Pass did not receive a strong refreeze the morning of 5/3.  Expect wet loose conditions to develop quickly in the day, especially if incoming clouds hold off longer than forecasted.  Avoid slopes where the snowpack has become isothermal, and traveling on or below cornices.

5/2-5/3 will be the last weekend for public avalanche forecasts for the 2019/20 season.  Thanks to everyone who contributed and used the forecast this season!
