A hurricane is coming off the coast of Africa towards the United States in August. There are two winds that are propelling the hurricane: the westerlies and the trade winds. The trade winds have an average speed of 13mph while the westerlies have an average speed of 5mph. Depending on the differences between the two wind speeds, the hurricane will either move east, west, or northeast. The hurricane also has a minimum speed of 74mph, and as its speed increases, its capability of destruction increases.
