PNW Snow Alert: 100 Inches Forecasted for Washington Cascades

A powerful atmospheric river is sweeping across the western United States, funneling a deep plume of moisture directly into the Cascades and British Columbia. Forecasters are calling for staggering snowfall totals, with some regions in Washington's Cascades expected to see up to 97 inches of accumulation over the next several days. However, the transition from a cold start to a mid-week warm-up could create "upside-down" snow conditions, and high winds are expected to cause significant lift holds and potential closures at exposed resorts.

Why it matters

This atmospheric river event is a season-saver for many resorts in the central and southern Cascades that have struggled with low base depths this winter. The influx of moisture will ensure that the spring season will be deep, stable, and full of the legendary PNW terrain.

The details

The "March Miracle" is officially arriving in the Pacific Northwest with a vengeance. A massive atmospheric river—a "river in the sky" carrying moisture equivalent to the flow of the Amazon—is currently sweeping across the western United States. It is funneling a deep plume of moisture directly into the Cascades and British Columbia. While parts of the Rockies have seen a "hit-or-miss" season, this storm is expected to be a total game-changer for resorts in Washington and Northern Oregon.

• The Washington Cascades are the bullseye for this cycle, with forecasters calling for staggering totals from March 9-14.
• A cold reload is already underway as of Monday, March 9, with snow levels hovering near 1,500 feet.
• A mid-week surge brings warmer air, which could create "upside-down" snow conditions on Wednesday and Thursday.
• Friday looks to bring a cooler pulse, potentially "righting" the snowpack with a fresh layer of blower on top of the heavy base.

What’s next

Skiers and snowboarders should check their local avalanche center for updates on snowpack stability and potential hazards before heading out into the backcountry during this intense weather cycle.
