Have we turned the corner to Spring meltdown? I don’t think we are quite there in the avalanche sense, but cold below-freezing temperatures are getting to be rare. With rain and no freezing below 2000 feet, watch for surface snow to be pushable, especially late in the day. If loose, water saturated snow gets to be deeper than about 6 inches, it is a sign that the snowpack is losing strength.
Wet avalanche activity is most likely to be found below 2000 feet late in the day. If the sun is shining, then south aspects may be more prone to this problem.
We saw evidence of one small wind slab 2 days ago on the RWIS camera pointed at Eddy’s. This is very minor for an avalanche, but it is an indicator of larger possibilities in bigger terrain. We may still be able to trigger pockets like this in the higher starting zones around Turnagain Pass.
Wind during that last storm on the 13th-14th was predominately from the east. Look for more wind slab formation on west aspects.
A shot of snow a few days ago laid a thin layer of new snow on the surface, but did not produce much for avalanche activity.
Today’s weather will include some rain, mixed with snow at higher elevations. Snowfall amount will be miniscule. Temperatures are barely reaching freezing at night up to about 2000 feet. Variable wind to 10mph.
The rest of the work week looks like the same pattern, with a chance of rain and warm temperatures. The next chance for sun comes on Saturday and Sunday.
