How to Read the Wind Data

Wind roses show how often wind blows from each direction. Longer petals mean wind came from that direction more frequently. Color shows speed: blue is calm, darker blue is moderate, red is strong.

The timeline arrows point in the direction the wind is blowing toward — the way snow would drift. If you face the direction the arrow points, the wind is at your back.

Arrow pointing up (north) = wind blowing from south to north. Snow drifts northward.
Red arrow pointing east = strong wind from west. Expect wind-loaded east-facing slopes.

For skiing: Wind-loaded slopes (leeward side) accumulate deeper but less stable snow. The rose helps identify which aspects have been wind-affected and which will be affected next.

Speed guide: Under 15 mph is comfortable on a chairlift. 15–30 mph causes exposed lifts to slow or hold. 30+ mph typically means upper lift closures and dangerous ridgeline conditions.

About Willamette Pass

Snow depth at Willamette Pass is measured daily by SNOTEL station #388, located at Cascade Summit, Willamette Pass, Oregon at an elevation of 5,100 ft. This automated sensor is operated by the Natural Resources Conservation Service (NRCS) and has been recording continuous snowpack data since 1979.

This page provides current snow depth, snow water equivalent (SWE), 24-, 48-, and 72-hour new snowfall totals, snow density and quality analysis, and historical season rankings spanning 47+ years of records. Snowpack is ranked against every prior season on record, showing where the current winter stands historically for Willamette Pass.

The 5-day weather forecast uses Open-Meteo data at three elevation zones: Gold Lake (4,600 ft), Cascade Summit (5,100 ft), Peak 2 (6,700 ft). Wind speed, direction, and gust data are shown for both the past 48 hours and the next 48 hours at each elevation, with interactive wind rose visualizations.

Following the Northwest River Forecast Center’s (NWRFC) discontinuation of snow depth and snow density graphs in June 2025, Cascade Snow provides a free, daily-updated alternative with interactive historical charts and comprehensive snowpack analysis for Oregon’s Cascade mountains. All data is sourced directly from Natural Resources Conservation Service (NRCS) sensors and updated automatically each morning.
