The highest gusts of 50 to 60 mph will whip the California High Desert eastward to northern Arizona, southern Utah and southwestern Colorado.
Gusts will reach at least 40 mph over a wider swathe of the interior Southwest as far east as the southern High Plains.
As is often true in the Southwest, the winds on Sunday will make for tricky driving, especially for high-profile vehicles. The winds will stir up dust and sand with visibility locally reduced.
