Questions

What is snow water equivalent (SWE)?

SWE is the depth of water you would get by melting the whole snowpack. Willow Park's 1″ of snow holds 0.6″ of water, so the pack is about 60% water. Fresh powder is often 5 to 10%; old spring snow can be 40% or more.

How often does Willow Park SNOTEL update?

The station reports every hour by radio telemetry to the USDA Natural Resources Conservation Service. This page refreshes each hour. Readings are provisional until NRCS quality control.

What does “% of median” mean?

It compares today’s SWE with the 1991–2020 median for the same calendar day at this station. Above 100% means more water in the snowpack than on a typical year’s same date.

Where is Willow Park SNOTEL?

At 10,710 ft in Larimer County, Colorado (40.4340°N, 105.7359°W), in the Big Thompson basin.

How is the snow forecast made?

Vertex runs the HRRR, RRFS and GFS weather models at the station’s own elevation and carries the measured snowpack forward hour by hour. Treat it as guidance, and check your avalanche center’s forecast before heading out.
