High Wind in Okanogan Valley, Washington

A trained spotter reported roof shingles blown off and tree limbs down due to strong winds. Wind gust speed was estimated based on damage and local wind speeds.

A wet and vigorous low pressure system brought snow and strong winds across much Eastern Washington on the evening of November 12th into November 13th. The heaviest snowfall was near the Cascade Crest with 1 to 2 feet reported. Numerous locations in the northern mountains and mountain valleys received up to one foot. The heavy, wet snow impacted morning commutes and led to numerous school district closures on the 13th. There were many accidents on I-90 and state highways, especially through the Spokane - Coeur d'Alene corridor due to slushy, melting snow. The snow was followed by strong winds in the afternoon and evening, with gusts reaching 45-60 mph across the Palouse and parts of the Columbia Basin.
