The Dust Bowl got its name after Black Sunday, April 14, 1935. More and more dust storms had been blowing up in the years leading up to that day. In 1932, 14 dust storms were recorded on the Plains. In 1933, there were 38 storms. By 1934, it was estimated that 100 million acres of farmland had lost all or most of the topsoil to the winds. By April 1935, there had been weeks of dust storms, but the cloud that appeared on the horizon that Sunday was the worst. Winds were clocked at 60 mph. Then it hit.
I found this piece of information about the dust cloud quite interesting. It explains everything that happened in the dust cloud and why and what happened. Also on this website there are people own version on what happened during the dust cloud and what they had to do when it hit their home towns. It says that the winds got up to 60mph, which if we acted this section out would it be an idea to either have fans or something to show how powerful the winds were.
