Blowing Dust Potential

This product provides the potential for blowing dust in the Yakima Valley, Columbia Basin and Foothills of the Blue Mountains zones. The categories (low, moderate, high and very high) indicate the threat of visibilities below one mile due to blowing dust. This product is intended to supplement but not replace or supersede other sources of forecast guidance. The values are calculated by an automated computer algorithm that uses National Weather Service wind forecasts and observed precipitation amounts as input.
