Suppose the hurricane in Figure 2 has stalled off the southeast
coast of the United States. Further suppose that the peak winds
around the storm are 115 mi/hr and that its central pressure is 934
millibars (27.58 inches). If the hurricane begins to move due west
at 10 mi/hr, answer the following questions assuming that the
hurricane experiences no change in its intensity.
