An upslope storm is bringing snow and wind to the south Rockies, likely forming fresh wind slabs at higher elevations.
An upslope storm will bring up to 20 cm of snow and strong northeast winds along the Continental Divide, forming fresh wind slabs in open areas and along ridgelines.
Cornices along ridgelines are very large and looming. They weaken with progressive warming and could fail at any time.
No recent avalanche activity has been reported.
By Wednesday afternoon, up to 20 cm of new snow is possible, accompanied by strong northeast winds.
Around 10 cm of dry, soft snow from the weekend may linger on shady alpine slopes, while a thick melt-freeze crust dominates elsewhere. This crust may soften during the day and refreeze overnight.
There are no concerning layers in the middle or lower snowpack.
The snowpack is rapidly melting at lower elevations.
