Weather Forecast

The blocking pattern i breaking down and we will see the first in a series of weak storms Tuesday night. By Friday the pattern will have changed and snowfall is likely.

Snowpack Summary

Another hard freeze overnight made for excellent travel. True corn is forming on low to mid elevation solar aspects with a thinner crust in the high alpine. Due north slopes have a mixture of wind effect and thin facetted snow with low penetration.

Avalanche Summary

A widespread spring cycle up to size three has been occurring on solar aspects starting mid afternoons. Deep wet slabs have been coming out in isolated locations on steep solar aspects late in the day., and some slabs have been observed failing at the bottom of the snowpack in shallow snowpack areas.. Cornices have been falling off also.

Confidence

Timing, track, or intensity of incoming weather system is uncertain on Wednesday
