It will just be normal down canyon winds but the terrain forms a half bowl to the west on 222 and a north south ridge on the south side of horseshoe bend. The wind usually comes over the top at corrine lake where the head of the fire is and comes out of the south at the heel. They had problems with this immediately when the corrine fire started.
The willow and north fork fire had the same issues every night on their south flank. I watched the willow fire for six nights each day mud was laided down till dark and once the wind shifted during the night it would burn through or spot across the retardant.
