Blowing Dust

Blowing dust was the cause of several vehicle accidents and road closures across Washington's Central Basin. The dust severely restricted visibilities on Interstate 90 as well as several adjoining highways between approximately 10 a.m. and 5 p.m. PST.

According to satellite estimates, the dust reached as high as 4.5 km into the atmosphere.
