New snow and moderate winds from a variety of directions may form touchy wind slabs reactive to human triggers.

    Any appearance of the strong April sun can initiate a loose wet avalanche cycle. The likelihood of loose wet avalanches increases as temperatures warm through the day and/or if the sun comes out for a prolonged period of time.

Confidence

Low - Forecast snowfall amounts are uncertain

Avalanche Summary

Numerous natural loose wet avalanches were reported on solar aspects on Thursday. There are currently very few professional observers submitting daily observations. Please submit your observations to the MIN. Photos of avalanches or current conditions are particularly useful.

Snowpack Summary

5-15 cm. of new snow sits on a crust everywhere except high north facing terrain. Wind slabs created by last weeks storm may still linger in lee terrain below ridgetops. A layer of surface hoar (weak, feathery crystals) in the upper snowpack could still be reactive to human triggers in isolated locations such as high elevation, north facing terrain.

Below treeline, snow is disappearing rapidly.
