How were the coastline segments determined?
We used U.S. landfalls of named storms during 1950-2004 to determine coastline segments having approximately equal historical probabilities of landfall. For the U.S. Gulf Coast, including the Florida Keys, approximately 12.5% of the storms that have landed in the U.S. first landed in each of the eight coastline segments. Similarly, for the U.S. Atlantic coast, excluding the Florida Keys, approximately 12.5% of the storms that have landed in the U.S. first landed in each of the eight coastline segments.
