This work investigates gap winds in a steep. deep river canyon prone to wildland fire. The driving mechanisms and the potential for forecasting the gap winds are investigated. The onset and strength of the gap winds are found to be correlated to the formation of an along-gap pressure gradient linked to periodic development of a thermal trough in the Pacific Northwest. https://countryscenesaddleryandpetsuppliers.shop/product-category/cross-body-purses/
