When we think of dust storms, the image that comes to mind is that of the Dust Bowl. On November 13, 1933 the first dust storm of the great dust bowl era of the 1930s occurred. The dust storm, which had spread from Montana to the Ohio Valley the day before, prevailed from Georgia to Maine. It resulted in a black rain over New York and a brown snow in Vermont. Parts of South Dakota, Minnesota and Iowa reported zero visibility on the 12th. On the 13th, dust reduced the visibility to half a mile in Tennessee.
