several days prior to reaching land the National Hurricane Center had been predicting the hurricane would
come on shore between Cape Fear, North Carolina, and the North Carolina-Virginia border. It was
estimated that the probability the hurricane would actually strike in this area was 0.94. In fact, the hurricane
did come on shore almost exactly as forecast and was almost in the center of the strike area. The National Hurricane Center forecasts that the hurricane will hit the strike area with a probability of 0.94.
