Snoqualmie Pass has largest snowpack in a decade, WSDOT says

A significant amount of snow has fallen in the Olympics and Cascades this season.

SNOQUALMIE PASS, Wash. — Snoqualmie Pass has received a significant amount of snow this season, pushing its snowpack to levels not seen in about a decade.

The pass had a snowpack of 128 inches as of Feb. 19, according to data from the Washington State Department of Transportation (WSDOT).

On Feb. 23, snowfall surpassed the 10-year average with 375 inches.

Last season's snowfall total was about 345 inches.

Over the past 10 years, snowfall has ranged from 104 inches to 470 inches.

This season, Stevens Pass has received 378 inches of snow and had a snowpack of 127 inches, as of Feb. 19.

Snoqualmie Pass isn't alone in its above-average snowpack totals.

Snowpack is above-average for much of Washington state, especially in the Olympics and Cascades. Snowpack can be measured through the depth of water that would result if the snowpack in an area melted instantly - known as the snow water equivalent.

As of Feb. 19, the Olympics had a snowpack of 144% of the median between 1981 and 2010. The west side of the Cascades is seeing generally 120% snowpack, with the central Cascades at 127%.
