Strong westerly winds will transport fresh snow into dangerous slabs at upper elevations. You can trigger an avalanche on any wind-drifted slope, even open slopes below treeline. In terrain features where freshly drifted snow accumulates more than a couple feet deep, an avalanche may break deeper into buried weak layers, growing large and destructive. Look for safer terrain in wind-sheltered areas below treeline not exposed by large avalanche paths above.
