Areas closer to the boundaries of the Matanuska and Susitna River Valley proper likely saw more wind effect in the most recent wind events, such as Mt Souverin. These wind events produced strong winds through the main river valleys but spared the heart of Hatcher Pass. A consideration to keep in mind are long valleys with fetch. Northerly winds were likely stronger through Little Susitna River Valley and Moose Creek. The quantity and low density of snow would make it easy for winds to create wind slabs failing on widespread weak snow. This is a great example of how our forecast can have high accuracy for the main forecast boundary area, but variations in conditions can still exist in specific or isolated areas, and in peripheral zones.
