December Snow Report

The 2024-2025 snow year continues to be developing nicely in the San Juan Mountains. Although the La Niña pattern that was predicted for this year remains weak, the jet stream has established itself across Colorado and, as a consequence, there were a number of good snowfalls in the San Juans during November. Silverton received 10.6” for a yearly total so far of 21.1” (less than the long term average, but the most since the 2019-2020 snow year). The snowpack at the Red Mountain SNOTEL site is currently at 34” (SWE of 7.9”). Basically, a very good start to the snow year; let’s hope the trend continues through December and January.
